Frequently Asked Questions About Asia eSIMs
What is the best eSIM for Asia?
SimCorner stands out as the best eSIM for Asia, balancing top-tier network coverage, flexible data packages, instant email delivery, and seamless QR code activation. Whether you are travelling for work or vacation, our eSIM Asia plans deliver local 5G/4G speeds with no roaming fees.
Can I use the eSIM Asia for navigation while taking the train in Taiwan or South Korea?
Yes, our eSIM Asia is designed to maintain a stable 5G or 4G connection even while travelling at high speeds on major rail corridors. This includes the KTX in South Korea and the THSR in Taiwan. The eSIM for Asia allows you to track your journey in real-time, book connecting transport, or stream entertainment without the frequent signal drops often associated with traditional roaming.
How is eSIM connectivity like in Bali and Phuket?
While our eSIM Asia provides robust coverage across 27 countries, signal strength in remote islands like Bali or Phuket depends on local infrastructure. In most tourist regions and beaches, you will enjoy reliable 4G or 5G connectivity. However, in deep jungle areas or remote mountain treks, speeds may naturally dip. Our Asia travel eSIM automatically switches to the strongest available local network to maintain your connection.
Can I use the eSIM Asia to book rides on the Grab app?
Yes, your eSIM Asia is perfect for using essential travel apps like Grab in Thailand, Vietnam, and Malaysia. Because it provides a high-speed data connection, you can pin your location, message drivers, and process digital payments efficiently. Staying connected ensures you can navigate cities safely and avoid the high costs of traditional street taxis during your trip.
What happens if I run out of data on a 1–50GB Asia travel eSIM plan?
On a fixed data plan, your connection will stop once the limit is reached. To get back online, you can conveniently top up via the SimCorner app or purchase a new plan for instant 5G/4G access. If you prefer uninterrupted service, our unlimited eSIM for Asia plans are a great alternative, as they keep you connected even after high-speed daily limits are met.
Will the eSIM Asia work if I travel between Thailand and Vietnam?
Our eSIM Asia is specifically designed for multi-country travel across 27 destinations. When you cross the border from Thailand to Vietnam, your eSIM in Asia will automatically detect the new local network and reconnect without any manual configuration. This eliminates the need to buy separate SIM cards at every border, providing continuous connectivity throughout your entire trip.
How does the unlimited data reset work on the Asia tourist eSIM plan?
For our eSIM Asia unlimited data plans, transparency is key. You receive a daily 3GB allowance of high-speed 5G/4G data. If you happen to use this entire amount, your speed will reduce to 128 kbps for the remainder of the day, ensuring you are never fully offline. Your high-speed access then automatically restores every 24 hours from your initial activation time, keeping you ready for the next day.
Will this eSIM work during a layover in Asia?
Yes, our eSIM for Asia will work during a layover by automatically connecting to the local high-speed network. However, your transit stop should be among our covered Asian destinations. You can reliably browse, message, and use airport apps during your layover without buying a separate transit pass or changing any settings.
Is 5G connectivity available in major cities like Seoul and Taipei?
Yes, cities like Seoul and Taipei are global leaders in 5G infrastructure. Your eSIM Asia will prioritise these ultra-fast 5G networks in high-density urban areas, providing the bandwidth needed for HD video streaming and instant navigation. Even in crowded districts like Ximending or Gangnam, you can expect stable, high-speed performance that often outperforms standard Australian telco roaming.
Can I use translation apps to read menus in Vietnam or China?
Your eSIM Asia provides the reliable high-speed data required for real-time translation tools like Google Lens. Whether you are decoding menus in a Ho Chi Minh City cafe or reading street signs in Shanghai, the low latency of our 50 affiliate networks ensures instant results. This makes navigating foreign languages much easier, allowing you to travel with confidence and interact more deeply with local cultures.
Does the eSIM Asia come with a local phone number?
This is a data-only travel eSIM and does not include a local Asian phone number for traditional voice calls or SMS. However, you can maintain full voice and text connectivity by using data-based apps like WhatsApp, FaceTime, Viber, and Messenger. This allows you to stay connected with high-speed data without the privacy risks, mandatory passport uploads, or long retail queues associated with local SIM registrations.
When is the best time to install my eSIM Asia data plan?
We recommend installing your eSIM Asia before departure or at the airport before boarding. The installation requires a stable internet connection. Completing this step ahead of time ensures that your eSIM is ready to connect instantly upon arrival.
Note: Some eSIMs activate directly upon scanning the QR code. Check ‘Things to Know’ on the product page, or refer to your post-purchase email for your custom setup guide.How do I install and activate my eSIM Asia?
- iPhone: Go to Settings > Mobile > Add eSIM.
- Android: Go to Settings > Connections > SIM manager > Add eSIM.
Do I need an active internet connection to install my Asia eSIM?
Yes, a stable Wi-Fi or cellular data connection is mandatory during the initial installation phase. Your device must communicate directly with the network servers to download the digital eSIM profile. Attempting to install the eSIM Asia without an internet connection will result in a setup failure.
Note: Most SimCorner eSIMs do not need internet for activation. Enabling data roaming triggers the activation.Can I install the Asia eSIM using a screenshot or image from my gallery?
Yes, with most modern iOS and Android devices, you can upload a screenshot or image directly through the Add eSIM menu. If your specific device does not support gallery uploads, you can display the Asia eSIM QR code on a laptop, tablet, printout, or secondary screen and scan it using your phone's camera.
When does the validity countdown start, and how are days calculated?
The validity period does not begin upon purchase or installation. The countdown starts only when your eSIM Asia gets activated by connecting to a supported local network. From the activation time, your plan days are calculated based on continuous 24-hour cycles.
Does the Asia eSIM expire if left unactivated?
No, our Asia eSIM does not expire or get auto-activated, unlike many other eSIM providers who enforce 15–30-day activation periods. You can safely purchase your eSIM data plan months in advance during a sale or while planning your itinerary. Your eSIM Asia remains dormant and ready for use whenever your trip begins.
Can I transfer my active eSIM Asia profile to another phone?
No, travel eSIMs are single-use digital profiles that lock to the physical hardware of the initial device. Once a QR code has been scanned, it cannot be transferred to a different handset. Additionally, if you delete the profile from your settings, it cannot be re-scanned or reused.
How do I track my data balance and purchase top-ups?
You can use the SimCorner App for live data tracking and instant on-the-go recharges.
If you prefer not to use the app, you can also monitor your usage directly through your device's native cellular settings. Please note that top-up availability varies by product, so be sure to check your specific product details before purchasing to confirm if your chosen plan is eligible for recharges.How do I check if my device is eSIM compatible?
iOS:
Go to Settings > General > About
Scroll down to Available SIM (or Digital SIM).
If an IMEI or EID number is listed, your iPhone supports eSIM.
Android:
Dial *#06#on your keypad.
If an EID (Embedded Identity Document) number appears on your screen, your device supports eSIM.
How do I check if my device is carrier-unlocked?
iOS: Navigate to Settings > General > About and find Network Provider Lock. If it says No SIM restrictions, your device is unlocked.
Android: The most accurate test is to temporarily insert a physical SIM card or install an eSIM from a different mobile network. If your phone connects to the network and you can make a call or use data, your device is unlocked.Can I use Asia eSIM if my phone is currently locked to a network carrier?
No, you cannot use an eSIM Asia if your phone is locked to your home provider. Carrier-locked phones automatically reject any third-party travel eSIM profiles. You must contact your current carrier to fully unlock your device before attempting to install or activate our Asia travel eSIM.
Why are iPhones from Mainland China, Hong Kong, or Macau incompatible?
Apple manufactures iPhones for the Chinese, Hong Kong, and Macau markets without an internal eSIM chip. To comply with local regulatory demands and consumer preferences, Apple replaced the eSIM hardware entirely with a dual-sided physical tray for nano-SIMs.
Got an iPhone from one of these regions? Explore our physical Asia SIM card options.
How many eSIM profiles can I store and run on my phone at the same time?
Storage: Most modern smartphones allow you to download and store between 5 and 10 distinct eSIM profiles directly on their internal chip.
Usage: While you can store many, you can generally only run one or two profiles actively alongside your primary home SIM card at any given time, depending on your device generation.
Will this eSIM work on a jailbroken (iOS) or rooted (Android) device?
Yes, but we cannot guarantee optimal network performance because jailbreaking or rooting modifies core security protocols. Security flags within cellular operating systems can occasionally interfere with the profile registration process or prevent automatic network connections.
Can I keep my home SIM in my phone alongside the eSIM Asia?
Yes, modern smartphones feature Dual SIM technology, allowing your physical home SIM and your digital eSIM Asia to run simultaneously. You simply assign data usage to your SimCorner profile while keeping your home line active for incoming OTPs.
Note: Receiving incoming calls will trigger roaming charges from your home provider.Can I keep my original WhatsApp and iMessage accounts?
Yes, these services are linked to your home phone number or account rather than the SIM card. When you insert your eSIM Asia, your apps may prompt you to update your number—always select Keep Existing Number. This ensures your account, chat history, and contacts remain tied to your home number, allowing you to message and call as usual throughout your trip.
Does my Asia unlimited data eSIM have a hidden Fair Usage Policy (FUP) throttle?
No, we believe in complete transparency. Unlike other providers who hide their speed drops in fine print, our limits are fully disclosed up front. Your eSIM Asia unlimited plan includes:
- High-Speed Data: 3GB of 4G/5G data per day.
- Speed After 3GB: If you exceed 3GB in a day, your speed drops to 128kbps.
- Reset Time: Every 24 hours from the exact time of your initial activation.
Can I still receive bank SMS codes (2FA) while using eSIM Asia?
To receive bank verification SMS codes (2FA) using our eSIM for Asia, your device must support Dual SIM functionality so your home SIM remains active alongside your travel plan.
Pro-Tip: If your phone only runs one active SIM at a time, your home line will become temporarily inactive. To prevent losing account access, we highly recommend setting up email-based 2FA or an authenticator app before you depart.My trip was canceled; can I get a refund if I haven't used the eSIM?
Yes, you can get a refund. Please reach out to our 24/7 customer support as soon as possible.
If your travel plans change or your trip is canceled, SimCorner offers a flexible refund policy for unused profiles. As long as your eSIM Asia has not been installed or activated on a device, you are eligible for a return and refund.What are the SimCorner 5% price beat and 30-day price lock guarantees?
5% Price Beat: If you find an identical, cheaper travel plan from another provider, even on sale, we will beat their listed price by 5%.
30-Day Price Lock: If our own price falls within 30 days of your purchase, we will credit you the difference.
