FAQs About SimCorner eSIM for Vietnam
What is the best eSIM for Vietnam?
SimCorner stands out as the best eSIM for Vietnam, 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 Vietnam plans deliver local 5G/4G speeds with no roaming fees.
Does the eSIM Vietnam come with a local phone number?
This is a data-only travel eSIM and does not include a local Vietnamese (+84) 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.
Will my eSIM Vietnam work if I travel from Hanoi to Sapa by train?
Yes, your eSIM Vietnam is designed for mobility. Coverage remains strong along the main railway corridors and in Sapa. By using carriers like Viettel, which is known for its superior reach in the mountainous northern regions, you can maintain a steady data connection for navigation and social media even as you move between altitudes.
How do I get more data on my eSIM card Vietnam if I run out while in Ho Chi Minh City?
If you are on a fixed-data Vietnam travel eSIM plan, you can simply purchase a top-up via the SimCorner App to get back online instantly. If you are using our Vietnam Unlimited Data eSIM plan, you actually never run out. Even if you exceed your 3GB daily high-speed limit, your data continues at a reduced speed (128kbps) until it automatically resets at full speed every 24 hours.
Can I use my eSIM Vietnam to book rides on the Grab app?
Absolutely, you can use the eSIM Vietnam to book rides on the Grab app. The eSIM Vietnam provides the high-speed data required for real-time GPS tracking and instant messaging within the Grab app. Having a reliable eSIM connection is the most efficient way to secure safe and affordable transport throughout the country, whether you land at Tan Son Nhat Airport or explore the streets of Da Nang.
Is the Vietnam Unlimited Data eSIM plan truly unlimited for my trip?
The plan provides unlimited data for the duration of your trip, but it comes with a Fair Usage Policy (FUP). It includes 3GB of high-speed 5G/4G data every 24 hours. If you exceed this daily limit, your speed gets reduced to 128kbps for the remainder of the cycle—enough for WhatsApp and navigation—and automatically resets to full speed every 24 hours from your activation time.
Will I have coverage while visiting the beaches in Phu Quoc?
Yes, the carriers provided in our plans, such as Viettel, VinaPhone, and MobiFone, offer excellent coverage across Phu Quoc Island. Your eSIM Vietnam will easily let you share photos from the beach, verify flight statuses, and use translation apps at local seafood markets without needing to hunt for often-unreliable public Wi-Fi hotspots.
Can I use this eSIM Vietnam without submitting my passport or biometric data?
Vietnam’s Decree 49 mandates that all local SIM users provide passport details and facial biometrics at a physical store. SimCorner’s pre-registered Vietnam travel eSIM allows you to bypass these strict requirements, so you won't need to share sensitive documents or wait in airport queues. You can simply activate your plan online and connect to Viettel or Vinaphone the moment you land.
Can I use the hotspot feature to share the Vietnam eSIM data with my partner?
Yes, our eSIM Vietnam unlimited and extended (20–100GB) plans support personal hotspots. You can easily share your data allowance with other devices, such as a laptop or another smartphone. This is particularly useful for families or couples traveling together through Vietnam who want to stay connected using a single primary data plan. Please note that our 1–50GB plan does not include any hotspot allowance.
What happens if I land at Da Nang Airport and the eSIM for Vietnam doesn't connect?
While our eSIMs Vietnam are highly reliable, we offer 24/7 support if you encounter issues. Simply connect to the free airport Wi-Fi and reach out via email. Most connection issues are resolved by simply toggling the Data Roaming switch to ON for the SimCorner Vietnam eSIM in your cellular settings, which is required for the eSIM to communicate with local Vietnamese towers.
Is 5G data available everywhere in Vietnam?
5G is widely available across Vietnam, covering roughly 90% of the population, including all major urban areas, regional towns, and tourist hubs. In more remote rural areas or during long-distance transit between provinces, your eSIM Vietnam will automatically switch to the country's near-flawless 4G/LTE network. This ensures you maintain the strongest and most stable data connection possible, whether you are in a high-tech city or a traditional village.
When is the best time to install my eSIM Vietnam data plan?
We recommend installing your eSIM Vietnam 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 Vietnam?
- 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 Vietnam 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 Vietnam 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 Vietnam 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 Vietnam 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 Vietnam 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 Vietnam eSIM expire if left unactivated?
No, our Vietnam 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 Vietnam remains dormant and ready for use whenever your trip begins.
Can I transfer my active eSIM Vietnam 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 Vietnam eSIM if my phone is currently locked to a network carrier?
No, you cannot use an eSIM Vietnam 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 Vietnam 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 Vietnam 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 Vietnam?
Yes, modern smartphones feature Dual SIM technology, allowing your physical home SIM and your digital eSIM Vietnam 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 Vietnam, 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 Vietnam 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 Vietnam 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 Vietnam?
To receive bank verification SMS codes (2FA) using our eSIM for Vietnam, 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 Vietnam 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.
