Frequently asked questions
How do I know if my phone is compatible with a Vietnam eSIM?
Your smartphone must be carrier-unlocked and natively support eSIM technology, which includes most modern iPhones (iPhone XS and newer) and newer Android models. You can check your device settings for an 'Add eSIM' or 'Add Cellular Plan' option before purchasing. If your phone is locked to a specific home carrier, the eSIM will not work in Vietnam.
How much data do I need for a trip to Vietnam?
For standard navigation on Grab, Google Maps, and daily messaging, 1 GB to 2 GB per day is usually sufficient. If you plan to stream video, upload photos to social media, or work remotely, consider 3 GB per day or an unlimited plan. Free Wi-Fi is also widely accessible in Vietnamese cafes, restaurants, and hotels.
When should I install my Vietnam eSIM?
We recommend scanning the QR code and installing the eSIM onto your phone the day before travel while connected to a stable Wi-Fi network. Keep the eSIM line turned off until you land in Vietnam so the validity period does not start early. Upon arrival at airports like Hanoi (HAN) or Ho Chi Minh City (SGN), simply turn on the eSIM line and enable Data Roaming.
Will my WhatsApp, Instagram, and iMessage still work with a Vietnam eSIM?
all your messaging and social media applications will function normally with a Vietnam eSIM. WhatsApp and iMessage will remain linked to your primary phone number, so you do not need to re-verify your account. The eSIM simply provides the local internet connection required to run these apps seamlessly.
Does the Vietnam eSIM include a local phone number?
Most travel eSIMs for Vietnam are data-only packages and do not come with a local (+84) phone number for traditional voice calls or SMS. However, you can make internet-based calls and send messages through apps like WhatsApp, Zalo, Telegram, or Skype. For ride-hailing apps like Grab, you can register using your home phone number before you depart.
What should I do if my eSIM is not connecting to data in Vietnam?
First, verify that Data Roaming is switched ON for your eSIM profile in your phone's network settings. Next, ensure the eSIM is set as your designated Mobile Data source and toggle Airplane Mode on and off to reset the connection. If you still have no signal, manually select a supported local network such as Viettel or Vinaphone in your cellular settings.
Is a Vietnam eSIM cheaper than using my home carrier's international roaming?
a Vietnam eSIM is significantly cheaper than standard daily roaming rates from home carriers, which often cost $10 to $15 per day. eSIM packages offer prepaid local data rates starting at just a few dollars for your entire trip duration. This eliminates the risk of unexpected bill shock while giving you high-speed local 4G/5G coverage.
