Order/Payment Questions

At your convenience, we advise you buy the eSIM before your departure for Vietnam. By doing so, you will have time to install it to your phone before departure and then activate it upon landing in Vietnam and get yourself connected immediately.

Please note that your eSIM data plan with GoVietnamSim starts when you activate it, not at the time of installation, so your installation before departure will not affect your eSIM validity.

There are certain reasons leading to your failure to scan the QR code to your handset.

Looking at the following checklist to identify your exact issue:

Is your phone eSIM compatible?

If you’ve already checked and make sure that your phone is eSIM compatible and unlocked, move onto the next reason.

If you are not sure, please check it here.

Turns out your phone isn’t eSIM compatible or unlocked? Get in touch with us and we’ll find a solution.

Is your phone connected to WiFi?

An eSIM QR Code cannot be installed without Wifi connection. Therefore, if you fail to connect your phone with WiFi, you cannot scan it properly.

We recommend you installing your eSIM before departure to make sure you have a stable Wifi connection during your eSIM installation. However, please do not activate it before you arrive in Vietnam.

Try setting up the eSIM manually

If you still cannot scan your QR code, your phone’s camera might have certain problems. Then, try setting up your eSIM manually by clicking “Enter details manually” instead when you are prompted to scan the QR code. You will be invited to enter the SM-DP+ ADDRESS & ACTIVATION CODE, which are all sent to your QR Code email.

Have you already scanned the eSIM QR code?

An eSIM profile can be on one phone only. It will not work if you try to scan it after it’s already on a phone, and you might receive a message saying: “Unable to Complete Cellular Data change”.

In this case, go to your SIM card manager/cellular settings to see if the eSIM is on your phone. If not, contact us for assistance.

If your eSIM QR code still doesn’t work

If you have tried all the things above and still cannot add the QR code to your phone, please contact us via:
