One App. 200+ Countries. Instant Data — Without Changing Your SIM or Paying Roaming Rates.

Yesim is not just a data plan — it is a travel connectivity platform built to eliminate every friction point of staying connected internationally. From the moment you land to the moment you leave, here is exactly what Yesim gives you.

📡

Instant eSIM Activation — QR Code Setup in Under 5 Minutes, No Physical SIM Required

The defining advantage of Yesim over traditional travel SIM cards and roaming add-ons is the complete elimination of physical SIM logistics. Traditional travel connectivity required either purchasing a local SIM card at the destination airport (queuing, paperwork, unfamiliar language, uncertain compatibility) or activating a roaming add-on from your home carrier at $10–$15 per day. Yesim replaces both with a process that takes under 5 minutes and can be completed before you even board the plane. Purchase your destination or global plan in the Yesim app, receive a QR code, scan it with your iPhone or eSIM-compatible Android device, and the eSIM profile installs directly onto your device. When you land and enable the Yesim eSIM from your device settings, you connect immediately to local partner networks in over 200 countries — with local data rates, local network speeds, and none of the per-day roaming charges that can add $150 or more to a 10-day business trip. The entire process from plan purchase to active connectivity can be completed on the taxi from the airport to your first meeting, meaning there is no window of disconnection between landing and needing to be reachable by colleagues, clients, or family.

🌏

200+ Countries Coverage — Regional & Global Plans for Every Travel Pattern

Yesim’s coverage architecture is designed to match every travel pattern that a business traveller, entrepreneur, or frequent flyer from Singapore and Malaysia is likely to need. Country-specific plans are available for individual destination travel — providing the most cost-effective data rates for a focused trip to a single country, whether that is a business visit to the United States, a conference in Germany, or a client meeting in Japan. Regional plans cover entire geographic zones — Southeast Asia, Europe, the Middle East, the Americas — providing unified data coverage for multi-city regional trips without requiring a new eSIM purchase for each country crossed. Global plans provide the widest coverage for travellers with complex itineraries crossing multiple regions on a single extended trip. For Singapore and Malaysia-based business travellers whose travel patterns typically include regional SEA destinations (Indonesia, Thailand, Vietnam, Philippines, Cambodia), key business hubs (Hong Kong, Japan, South Korea, UAE, UK, USA, Australia), and occasional regional travel across multiple continents — Yesim’s plan structure accommodates every combination with a matching coverage option at each price tier. The ability to purchase and activate a new plan mid-trip from the Yesim app — without returning to a SIM card kiosk or calling your home carrier — gives frequent travellers the flexibility to adapt their connectivity to changing itineraries in real time.

📞

Personal Virtual Number — Local Phone Number for Calls & SMS Without Revealing Your Home Number

One of Yesim’s most commercially valuable features for business travellers and entrepreneurs is the Personal Number add-on — a virtual local phone number in your destination country that enables you to receive calls and SMS messages as if you were a local contact, without giving out your home Singapore or Malaysia mobile number. For business travellers who need to be reachable by local contacts, rideshare services, hotel bookings, and client communications without accumulating missed calls on their home number or paying per-minute international call rates, the Personal Number bridges the communication gap that data-only eSIMs cannot address. The virtual number can be configured to forward calls to your home number, enabling a single device to effectively operate as a local number in the destination country while remaining reachable on the home Singapore or Malaysia number simultaneously — both of which remain active on a dual-SIM-capable device while the Yesim eSIM provides the data connectivity. For entrepreneurs and SME owners from Singapore and Malaysia who travel regularly to the same markets — Japan, Australia, UK, UAE — maintaining a consistent local number in each market through the Yesim Personal Number add-on creates a more professional local presence than sharing an international-format Singapore or Malaysia number for every business interaction in that market.

📱

Dual SIM Capability — Keep Your Home Number Active While Yesim Handles Local Data

A critical operational advantage of eSIM technology that makes Yesim superior to a physical travel SIM card is the ability to run two SIM profiles simultaneously on any eSIM-capable device — your home Singapore or Malaysia SIM card (for calls, home SMS, and WhatsApp Business continuity) and the Yesim eSIM (for local data connectivity at destination rates). This dual-SIM-in-one-device architecture eliminates the most painful trade-off of traditional travel SIM card use: the choice between keeping your home number accessible and having affordable local data. With Yesim, both are active simultaneously. Your home Singapore number continues to receive calls and messages — visible to colleagues, clients, and family as if you never left — while the Yesim eSIM provides high-speed local data at local rates for browsing, maps, email, Zoom calls, and everything else that requires data. For business travellers and SME owners from Singapore and Malaysia, this means your home-market clients and colleagues remain able to reach you on your normal number throughout the trip, while you are not paying $15/day to your home carrier for the privilege of being reachable. The transition is invisible to everyone contacting you on your home number.

💰

Zero Roaming Fees — Pay Local Data Rates Instead of $10–$15/Day Home Carrier Surcharges

The financial case for Yesim is straightforward and significant for any frequent business traveller from Singapore or Malaysia. The standard roaming add-on from Singaporean and Malaysian carriers for travel to major business destinations — United States, United Kingdom, Japan, Australia, UAE — typically costs between SGD $15–$35 per day or a bundled monthly rate that still significantly exceeds what Yesim charges for equivalent data on the same destinations. A 7-day business trip to the US or Europe with roaming enabled from a Singapore carrier can add SGD $105–$245 in data charges. The equivalent Yesim plan for the same destination and equivalent data is typically a fraction of this cost — purchased from the Yesim app before departure, active the moment you land, and charged at local network rates rather than home carrier international surcharge rates. For a Singapore-based founder or business owner who travels 8–12 times per year to international business destinations, the annual saving from switching from home-carrier roaming to Yesim is typically measured in hundreds to low thousands of Singapore dollars — money that funds additional travel, reduces business operating costs, or simply stays in the business rather than being paid to a carrier for the same data connectivity. The savings scale further for teams: a 4-person team travelling together for a week-long conference each on a $20/day roaming plan represents $560 in roaming charges for that single trip alone.

🔧

Yesim App — Manage All Your eSIMs, Plans, Data Usage & Personal Numbers in One Place

Yesim’s mobile application is the central interface for everything — purchasing and activating new eSIM plans, monitoring data usage in real time, topping up when a plan runs low, managing multiple eSIM profiles across different destinations, and configuring the Personal Number add-on for calls and SMS. The app is designed to be usable under travel conditions: at airports, in transit, or in the first minutes after landing in a new country where access to reliable Wi-Fi is not guaranteed. Plan purchases can be completed with a few taps and a saved payment method. QR code installation from within the app takes the friction out of eSIM profile installation on devices that support it. Real-time data usage monitoring ensures travellers are not caught by surprise by running out of data mid-trip — the app notifies users when usage reaches threshold levels and enables immediate top-up purchases before connectivity is interrupted. For business travellers managing multiple upcoming trips with different destination requirements, the app enables pre-purchasing and storing multiple eSIM profiles — activating each one when the relevant trip begins without requiring a new purchase at the point of departure. The app is available on both iOS and Android, with an interface calibrated for the quick-reference usage pattern of travellers rather than the extended configuration sessions of enterprise software.

Why Yesim? 4 Reasons It Beats Airport SIMs, Hotel Wi-Fi, and Home Carrier Roaming — Every Trip.

Airport SIM kiosks require queuing, paperwork, and hoping the card works in your device. Hotel Wi-Fi is unreliable, unsecured, and absent the moment you leave the lobby. Home carrier roaming is the most convenient option and the most expensive by far. Here is why Yesim specifically is the right choice for SEA business travellers and frequent flyers.

No Queue, No Kiosk, No Paperwork — Active Before You Land

The operational superiority of Yesim over traditional travel SIM cards begins before you even board the plane. Traditional travel SIM card acquisition requires either purchasing a local SIM at the destination airport — finding the right kiosk among confusing airport signage, waiting in a queue that can stretch to 30 minutes at peak arrival times, completing registration paperwork that may be in a language you do not read, and hoping the SIM is compatible with your device and activated before you need it — or ordering a tourist SIM online and waiting for physical delivery before departure. Yesim eliminates both processes entirely. The entire setup workflow — plan selection, payment, QR code receipt, and eSIM profile installation — is completed in the Yesim app before departure, from the comfort of home, office, or departure lounge. When you land, the eSIM is already on your device. You enable it from settings, and you are connected. The first call, map navigation, or Slack message can happen before you reach the immigration queue. For business travellers who book last-minute trips, who arrive at late hours when airport SIM kiosks are closed, or who simply cannot afford the time waste of a 30-minute queue before getting to the first meeting — this pre-activation capability is not a convenience, it is an operational necessity.

🔒

More Secure Than Hotel Wi-Fi — Cellular Data That Only You Access

The security vulnerability that most business travellers underestimate is hotel Wi-Fi. Hotel networks are shared infrastructure — every guest on the same network is a potential threat vector for man-in-the-middle attacks, credential harvesting, and session hijacking on devices that are not using a business-grade VPN. For business travellers accessing corporate email, cloud-based financial systems, client data, or sensitive business communications from hotel Wi-Fi — the risk exposure is significant and routinely underappreciated until a security incident makes it concrete. Yesim eSIM data uses your own dedicated cellular connection — a private, point-to-point data channel between your device and the local carrier network that other users cannot intercept or access. For Singapore and Malaysia-based SME owners and business professionals handling confidential client information, financial data, or sensitive business communications while travelling — Yesim’s cellular connectivity provides a materially more secure data channel than any hotel or airport Wi-Fi network, regardless of whether the hotel charges for the Wi-Fi access or not. The security argument for Yesim is not theoretical: it is the same reason corporate IT policies at large companies prohibit the use of public Wi-Fi for business applications and require VPN use — Yesim addresses the underlying problem at the connectivity layer rather than requiring an additional VPN subscription on top of an insecure network.

💼

Built for SEA Business Travellers — Coverage in Every Key Business Destination from Singapore & Malaysia

Singapore and Malaysia-based business professionals and entrepreneurs have a specific and well-defined set of international travel destinations that dominate their travel calendar: Southeast Asian regional markets (Indonesia, Thailand, Vietnam, the Philippines, Cambodia, Myanmar), major Asia-Pacific business hubs (Hong Kong, Japan, South Korea, Australia, India), the Middle East (UAE, Saudi Arabia), and key Western markets (UK, Germany, USA). Yesim’s 200+ country coverage encompasses every one of these destinations, with plan options at each destination calibrated to the data usage patterns of a business traveller — video calls, cloud access, maps, email, and business app connectivity — rather than the low-data patterns of a leisure tourist using social media intermittently. The regional plan architecture is particularly valuable for SEA-focused travellers: a single Southeast Asia regional plan covers an entire multi-country tour of the region, eliminating the need to purchase a separate country plan for each border crossing. For a Singapore-based entrepreneur visiting clients in Jakarta, Bangkok, and Ho Chi Minh City on a two-week regional swing — a single Yesim Southeast Asia regional plan provides continuous coverage across all three countries with one purchase, one QR code, and one activation.

💳

No Contract, No Subscription — Pay Only for the Trips You Take

Unlike home carrier roaming add-ons that require monthly subscription commitments, or MVNO travel SIM services that charge standby fees even in months where you do not travel, Yesim operates on a pure pay-per-trip model — you purchase a plan when you need it for a specific trip, and you pay nothing for Yesim in months when you do not travel internationally. This model is commercially superior for the majority of Singapore and Malaysia-based business travellers and entrepreneurs whose travel calendars are irregular: intensive travel months interspersed with months of primarily domestic business activity. The ability to purchase plans of different sizes for different trips — a lighter data plan for a 2-day regional visit where you will be primarily in client offices with office Wi-Fi, a larger plan for a 10-day international conference tour where data usage will be intensive — means you only pay for what each specific trip actually requires, rather than maintaining a uniform monthly data add-on subscription sized for your heaviest travel month and paying for unused capacity during lighter periods. The Yesim app stores your payment details for frictionless future purchases, ensuring that the no-subscription model does not add purchasing friction for repeat users — each new trip’s eSIM is purchasable in two or three taps from a returning user’s saved account, with the QR code ready for immediate installation.

Who Uses Yesim?

From a Singapore-based entrepreneur flying to a client pitch in London, to a Malaysian digital nomad working from Bali for a month — Yesim serves every traveller where reliable, affordable international data is the difference between a productive trip and an expensive, disconnected one.

✈️

Business Travellers — Reliable Data for Client Meetings, Conferences & Corporate Travel

For Singapore and Malaysia-based business professionals who travel internationally for client meetings, industry conferences, due diligence visits, or partnership discussions — the non-negotiable requirement is reliable, high-speed data connectivity from the moment of landing to the moment of departure. Missing a WhatsApp message from the client you are meeting in 30 minutes because your roaming plan was not activated correctly, or being unable to access the Keynote deck stored in iCloud because hotel Wi-Fi is too slow to load it, or failing to connect to the Zoom call with Singapore headquarters from a taxi in Tokyo because your data ran out — these are not theoretical inconveniences, they are commercially damaging failures of connectivity infrastructure on trips where every hour matters. Yesim’s pre-activation model ensures that by the time a business traveller lands, the data connection is already waiting — no activation delay, no airport queue, no dependence on hotel Wi-Fi. For corporate travellers whose companies have travel and expense policies, Yesim’s transparent per-trip pricing and in-app receipts simplify expense reporting compared to the opaque international charges that appear days later on a corporate mobile bill.

💻

Digital Nomads & Remote Workers — Long-Term International Data Without Carrier Lock-In

For digital nomads and remote workers who base themselves in different countries for weeks or months at a time — rotating between Bali, Chiang Mai, Lisbon, and beyond — Yesim provides a connectivity layer that moves with them without requiring a new carrier relationship and new physical SIM in every destination. The combination of country or regional eSIM plans for data and the Personal Number add-on for a consistent contactable phone number creates a travel connectivity stack that functions in every destination without the administrative overhead of managing multiple carrier accounts, SIM cards in different storage locations, and potentially expired prepaid balances across multiple telcos. For remote workers whose home base is Singapore or Malaysia but whose work routinely takes them to regional SEA destinations or further afield — Yesim’s plan library covers every destination at a cost that, amortised across the extended stays of a digital nomad rather than the short-stay context of a business trip, represents a compelling cost per gigabyte compared to roaming alternatives. The Yesim app’s data usage monitoring is particularly valuable for remote workers who rely on cellular data as their primary connection for video calls and cloud-based work applications — visible real-time consumption tracking prevents the mid-month connectivity crisis of an unexpectedly exhausted data balance.

🏢

SME Owners & Entrepreneurs — Cost-Effective Data for Founders Who Travel to Build Their Business

For SME owners and entrepreneurs from Singapore and Malaysia whose business growth depends on in-person relationship building across regional and international markets — the cost of international connectivity is a real and recurring business operating expense. Every trip to meet a potential investor in the UAE, a strategic partner in Japan, or a major client in Australia comes with data connectivity costs that, managed through home carrier roaming, accumulate to significant annual expenditure that reduces available capital for actual business growth. Yesim’s pay-per-trip pricing model, anchored at local data rates rather than roaming surcharges, converts the connectivity cost of a 5-day international business trip from a $100+ line item to a fraction of that — with no reduction in connectivity reliability or data speed. For founders managing the dual demands of cost consciousness and operational effectiveness that characterise the early-to-mid stage of building a Singapore or Malaysia-based business — Yesim represents the right trade-off: no sacrifice of connectivity quality or reliability, meaningful reduction in operating cost, and no contract or subscription commitment that persists in months where international travel does not occur.

🎒

Frequent Leisure Travellers — Holiday Connectivity Without Roaming Bill Anxiety

For Singaporeans and Malaysians who travel frequently for leisure — long-haul holidays to Europe, Japan, or Australia, regional SEA getaways, or short breaks to neighbouring countries — the connectivity challenge is balancing the desire to stay connected for navigation, accommodation bookings, and sharing with family and friends against the anxiety of returning to a roaming bill that materially reduces the value of the holiday. Yesim’s pre-trip plan purchase model reframes the connectivity decision: instead of activating roaming and watching an uncertain daily charge accumulate, travellers purchase a specific plan of known total cost before departure and use data freely up to the purchased volume. The psychological benefit of knowing the total connectivity cost before the trip begins — and knowing it is significantly lower than the roaming equivalent — is itself a material quality-of-life improvement for frequent leisure travellers who have historically either overpaid for roaming or under-used their devices abroad out of roaming bill anxiety. For families travelling together — each family member on their own Yesim plan — the aggregate saving versus four separate roaming add-ons on a 10-day holiday is meaningful enough to fund an additional night of accommodation at the destination, or more simply, to not think about the phone bill for the entirety of the trip.

🎓

Students & Young Travellers — Affordable International Data for Gap Years, Exchange, & Travel

For Singaporean and Malaysian students on overseas university exchange programmes, gap year travel, or extended international study — the connectivity requirements are continuous and the budget for connectivity is limited. Home carrier roaming at $15/day is financially unsustainable for a 3-month overseas exchange programme: $15 × 90 days = $1,350 in roaming charges that eliminate a significant portion of the discretionary travel budget for the entire exchange period. Yesim’s local data rate pricing makes extended-duration international data financially viable for students: a month-long plan at local network rates for a European exchange destination, a semester-long plan for a US or Australian university location, or flexible week-to-week plan purchases for backpacker-style travel through multiple countries. The eSIM installation process is designed for tech-savvy users comfortable with their device settings — the target profile of the typical Singaporean or Malaysian student — and requires no assistance from a carrier store or customer service representative. The absence of a contract or subscription commitment means students whose travel schedule is determined semester by semester can purchase Yesim plans that match their actual presence in each destination, without paying for a persistent international data subscription during term breaks when they are back in Singapore or Malaysia on their home network.

Yesim vs The Alternatives — Home Carrier Roaming, Airport SIMs, Airalo & Holafly

How Yesim compares to the most common connectivity alternatives considered by business travellers and frequent flyers from Singapore and Malaysia.

What You’re Evaluating Yesim Home Carrier
(Singtel / Maxis roaming)

Activation speed ✓ Instant QR — pre-activate before travel ✓ Pre-activated — but expensive daily rate ✗ Queue + paperwork at destination ✓ Instant QR activation ✓ Instant QR activation
Cost vs home carrier roaming ✓ Local data rates — fraction of roaming cost ✗ $10–$15/day — most expensive option Partial — local rates but compatibility risk ✓ Local rates — comparable to Yesim ✓ Local rates — unlimited data focus

Personal virtual number (calls & SMS) ✓ Available as add-on on Yesim plans ✓ Home number included (expensive/minute) ✓ Included with local SIM purchase ✗ Data only — no calls/SMS ✗ Data only — no calls/SMS
Countries covered ✓ 200+ countries with regional & global plans Partial — major markets, expensive in some ✗ Single destination only ✓ 200+ countries covered ✓ Large coverage — unlimited focus

No contract / pay per trip ✓ Pay only for trips you take Partial — monthly plan, pay whether you travel or not ✓ Buy per trip at destination ✓ Pay per plan purchase ✓ Pay per plan purchase

Yesim’s strongest competitive position versus Airalo and Holafly is the Personal Number add-on for calls and SMS — which Airalo and Holafly do not offer, making Yesim the superior choice for business travellers who need both data and a local callable number at the destination.

From Zero to Connected in 4 Steps — How to Set Up Your Yesim eSIM Before Your Next Trip

Most Yesim users complete their eSIM purchase, installation, and activation on the same day — often in the departure lounge or on the way to the airport. The process is designed for travellers who are already running on tight schedules and cannot afford a connectivity setup process that takes more than minutes.

1

Check Device Compatibility & Download the Yesim App

Before purchasing, confirm your device is eSIM-compatible. Most iPhone models from XS onwards (2018+) and recent Android flagships from Samsung, Google Pixel, and other major manufacturers support eSIM. Devices purchased in mainland China may not support eSIM due to local regulations — check your device specifications if unsure. Download the Yesim app from the App Store (iOS) or Google Play (Android) and create your account. The app is free to download; you pay only for the data plans you purchase. Note: eSIM functionality requires that the device is not carrier-locked. If your device is carrier-locked to your home carrier, you may need to request an unlock before a third-party eSIM profile can be installed — contact your carrier before departure if you are unsure of your device’s unlock status.

2

Choose Your Plan — Country, Regional, or Global — and Add a Personal Number if Needed

In the Yesim app, search for your destination country or select the relevant regional zone. Review the available plans for that destination — data volumes, validity periods, and prices vary by destination and Yesim updates its plan library regularly. Select the plan that matches your expected data usage and trip duration: for a 5-day business trip, a mid-volume plan with 5–7 days validity typically covers video calls, maps, email, and general browsing without risk of running out. If you need to receive calls or SMS on a local number — for ride-hailing, hotel bookings, client communications, or simply having a local number to share with contacts at the destination — add the Personal Number option at this step. Complete the purchase with your saved payment method. You will receive a QR code immediately upon payment confirmation.

3

Install the eSIM Profile — Scan the QR Code From Your Device Settings

eSIM installation is completed entirely within your device settings — no carrier store visit, no external tool, no technical expertise required. On iPhone: go to Settings → Cellular → Add Cellular Plan → scan the QR code provided in the Yesim app. On Android: go to Settings → Network → SIM → Add eSIM → scan the QR code. The eSIM profile installs in under a minute on a Wi-Fi connection. ThriveOnz360 recommendation: complete the eSIM installation before departure — ideally the day before travel — while you have access to reliable Wi-Fi and time to troubleshoot if anything goes wrong. Do not leave the QR code scan for the first few minutes after landing, as you will not yet have data connectivity to access the Yesim app if you need to retrieve the QR code again. Once installed, the Yesim eSIM profile sits on your device ready to activate whenever you need it.

4

Activate on Arrival — Enable the Yesim eSIM in Settings & Connect Immediately

When you land at your destination, go to your device’s cellular settings and switch the active data SIM from your home SIM to the Yesim eSIM profile. Your device will connect to local partner networks within seconds — typically faster than the time it takes to walk from the gate to immigration. Your home SIM remains installed and active for calls and SMS to your home number; only the data routing switches to the Yesim eSIM for affordable local data rates. Monitor your data usage in the Yesim app throughout the trip. If you approach the plan limit before your return date, top up directly in the app with a new plan purchase — delivered as an immediate top-up to your existing eSIM profile without requiring a new QR code scan. When you return to Singapore or Malaysia, switch the active data SIM back to your home SIM and your device reverts to normal home network operation.

Yesim FAQs

Everything business travellers, frequent flyers, and digital nomads from Singapore and Malaysia need to know before getting started with Yesim — including the honest answers about what it does exceptionally well and what to watch out for.

What is Yesim and how does an eSIM work?

Yesim is a global eSIM platform — available at yesim.app — that allows travellers to purchase and activate data plans for 200+ countries without a physical SIM card. An eSIM (embedded SIM) is a digital SIM card built directly into your phone. Rather than inserting a plastic card, you scan a QR code to install a carrier profile onto your device’s embedded SIM chip. This profile then connects to the carrier’s network at the destination. Yesim’s platform lets you purchase QR-based data plans for specific countries, regions, or globally — paying local data rates rather than roaming surcharges. Most modern smartphones (iPhone XS/2018+ and recent Android flagships) support eSIM. The Yesim app manages all your eSIM profiles, data usage, top-ups, and the optional Personal Number add-on for calls and SMS. You keep your physical home SIM active simultaneously on dual-SIM-capable devices — so your Singapore or Malaysia number remains reachable while the Yesim eSIM handles data at local rates. ThriveOnz360 recommends Yesim for business travellers, entrepreneurs, digital nomads, and frequent flyers from Singapore and Malaysia as the most cost-effective way to stay connected internationally.

Is my phone compatible with Yesim eSIM?

Yesim requires an eSIM-compatible device. Compatible devices include: iPhones from the XS model onwards (2018 and later) — including iPhone XS, XR, 11, 12, 13, 14, 15, 16 series and SE (2nd and 3rd gen); Samsung Galaxy S20 and later, Note 20 and later, Z Fold and Z Flip series; Google Pixel 3 and later; many recent models from Huawei (non-mainland China), Motorola, and other Android manufacturers. Important compatibility caveats: devices purchased in mainland China typically do not support eSIM due to local regulations requiring physical SIM cards. Carrier-locked devices may not accept a third-party eSIM profile — check with your home carrier whether your device is unlocked before purchasing. Older devices without embedded SIM hardware (pre-2018 iPhones, older Android models) cannot use eSIM regardless of software. When in doubt, check your device’s specifications page for “eSIM support” or “nano-SIM + eSIM” in the SIM section.

How much does Yesim cost and how does it compare to home carrier roaming?

Yesim’s pricing varies by destination, data volume, and validity period — confirm current rates at yesim.app before purchasing as rates are updated regularly. As a general benchmark: country-specific plans for popular business and leisure destinations typically start from a few dollars for short-duration light-data plans and scale up with data volume and validity length. This compares to home carrier roaming rates from Singaporean carriers (Singtel, StarHub, M1) that typically run SGD $15–$30 per day for international data packages, making a 7-day international trip cost SGD $105–$210 in data charges alone. Yesim’s local data rates are consistently a fraction of equivalent home carrier roaming charges for the same destinations, with the specific saving varying by destination. The Personal Number add-on is priced separately and varies by destination country of the virtual number. For a Singapore-based founder who travels internationally 8–12 times per year, the annual saving from Yesim versus home carrier roaming is typically significant — in some cases exceeding several hundred Singapore dollars annually for frequent travellers.

Can I make and receive calls with Yesim? What is the Personal Number?

Yesim’s core product is data — the eSIM plans provide mobile data connectivity, not voice calls or SMS by default. However, Yesim offers an optional Personal Number add-on that provides a virtual local phone number in the destination country, enabling you to receive calls and SMS on that local number. This is Yesim’s key differentiation from competitors like Airalo and Holafly, which offer data-only eSIMs with no call or SMS capability. The Personal Number works in conjunction with the Yesim app — calls to your virtual local number are routed through the app. This enables scenarios like sharing a local Japanese, UK, or US number with clients and contacts at the destination, receiving ride-hailing verification SMS, completing hotel check-in verification, and maintaining local contactability without sharing your home Singapore or Malaysia number with every contact at the destination. On dual-SIM capable devices, you can simultaneously receive calls on your home Singapore/Malaysia number (via the physical SIM) and on the Yesim virtual local number (via the eSIM) — providing full bi-directional call coverage in both your home and destination markets during the trip.

Can I use Yesim and keep my home Singapore or Malaysia number active?

Yes — this is one of the key operational advantages of eSIM technology over physical travel SIM cards. On any smartphone that supports dual SIM operation (which includes most eSIM-capable devices), your physical home SIM and the Yesim eSIM can both be installed and active simultaneously. Your home Singapore or Malaysia mobile number remains reachable for incoming calls and SMS — colleagues, clients, and family back home can call and message your normal number exactly as if you had not left. The Yesim eSIM handles the data routing — when you select Yesim as the primary data SIM in your device settings, all internet traffic uses the Yesim plan at local destination rates rather than your home carrier’s international roaming rates. This dual-active configuration is how most experienced business travellers and digital nomads use Yesim: home SIM for number continuity, Yesim eSIM for cost-effective data. The only limitation is on devices that restrict data to one SIM at a time — check your device’s dual-SIM data behaviour in settings to confirm both SIMs can operate simultaneously for their respective functions.

What happens if I run out of data mid-trip? Can I top up?

Yes — Yesim supports in-app top-up purchases. If your data plan runs out before your return date, open the Yesim app, navigate to your active eSIM profile, and purchase an additional plan for the same destination. The top-up is delivered immediately to your existing eSIM profile — no new QR code scan is required, and connectivity is typically restored within a few minutes of the top-up purchase. Yesim’s app includes real-time data usage monitoring that shows your remaining data balance and usage rate, enabling you to anticipate when a top-up may be needed and purchase proactively rather than reactively. ThriveOnz360 practical tip: for a first Yesim trip, consider purchasing a slightly larger data plan than you expect to need, or purchasing a secondary smaller plan to keep in reserve — the cost of the extra data is typically lower than the anxiety of running out during a critical moment of the trip. Top-ups require payment processing and brief activation time, so always top up with at least 15–30 minutes of data remaining rather than waiting until connectivity drops.

What are Yesim’s honest limitations? What should I know before buying?

ThriveOnz360 believes in transparent recommendations. Yesim’s limitations worth knowing before purchasing: first, data speeds vary by destination and local partner network — while Yesim connects to local networks, the specific speed you experience depends on the local carrier’s infrastructure and network load at the destination, which Yesim does not control. Second, the Personal Number add-on is an app-based virtual number rather than a traditional mobile number — call quality depends on data connection quality, and it may not work in all apps that require SMS verification (some verification systems reject VoIP numbers). Third, devices purchased in mainland China typically do not support eSIM, and carrier-locked devices may require unlocking before eSIM profiles from third parties can be installed. Fourth, Yesim eSIM plans are typically single-device — the data cannot be shared as a hotspot on all plans (check plan specifications for hotspot/tethering permissions if this is a requirement). Fifth, data rollover policies vary by plan — check whether unused data from a purchased plan carries over or expires at the plan’s end date. These are manageable considerations for the vast majority of travellers from Singapore and Malaysia using modern eSIM-capable devices on unlocked networks.

Is Yesim suitable for SEA travel? Does it cover Singapore, Malaysia, and regional destinations?

Yes — Yesim covers Southeast Asia comprehensively, making it well-suited for the travel patterns of Singapore and Malaysia-based business professionals and entrepreneurs. Coverage includes all major SEA markets: Indonesia (including Bali), Thailand, Vietnam, the Philippines, Cambodia, Myanmar, and others. Regional SEA plans are available for travellers covering multiple SEA countries on a single trip — a single plan covering the entire Southeast Asia zone eliminates the need for individual country plan purchases on multi-country regional tours. Beyond SEA, Yesim covers all major business and leisure destinations from Singapore and Malaysia: Japan, South Korea, Hong Kong, Australia, UAE, UK, Germany, USA, and others. For the specific travel patterns most common among Singapore and Malaysia-based founders and SME owners — regional SEA client visits, quarterly international conference attendance, leisure travel to Japan, Australia, or Europe — Yesim’s coverage architecture provides a matching plan option at every destination.
