Which network does FlySimGo use in Vietnam?

Does FlySimGo support 5G in Vietnam?

Can I install my Vietnam eSIM before I travel?

You can install the FlySimGo eSIM for Vietnam immediately after purchase — installing it alone does not start the plan. Validity begins only once you first use data on the local network at your destination, so buying and installing early doesn't waste any days.

When does my Vietnam eSIM validity start?

Validity for the FlySimGo Vietnam eSIM begins the moment your device first uses data on a supported local network — not from the purchase date, and not from installation alone. This means you can buy and install it days or weeks in advance without losing any validity time.

Can I keep my regular SIM and phone number while using FlySimGo in Vietnam?

On dual-SIM-capable devices, your physical SIM stays active for calls and SMS on your existing number while the FlySimGo eSIM for Vietnam handles mobile data. You can switch your default data line at any time in your device settings.

Can I use WhatsApp, Google Maps, and Uber with FlySimGo in Vietnam?

FlySimGo's eSIM for Vietnam provides a standard mobile data connection, so apps like WhatsApp, Google Maps, and Uber work the same way they would on any other mobile data connection — provided those services are available at your destination.

Can I top up my FlySimGo eSIM in Vietnam?

When your data for Vietnam runs low, you can buy an additional package without reinstalling the eSIM. You'll receive a low-data notification, and the top-up activates on the same eSIM.

Which phones are compatible with a Vietnam eSIM?

Compatibility depends on the device and carrier lock, not on the destination. Check under your device settings, Mobile/Cellular, to confirm eSIM support, and make sure the device is carrier-unlocked before installing the FlySimGo Vietnam eSIM.

What happens if I run out of data in Vietnam?

When your data runs low, FlySimGo notifies you, and you can purchase an additional package without reinstalling the eSIM. The top-up activates on the same Vietnam eSIM.
