How to Buy a SIM Card in Vietnam

A Vietnamese SIM card can be found almost anywhere from street vendors, phone shops, credit kiosks, at the  airport on arrival , and at travel agencies. Most other vendors cannot register the SIM card for you, so it’s best to buy from the official carrier stores. The most common networks are Viettel Mobile, MobiFone, Vinaphone, and Vinamobile.

TIP: Before getting a SIM, make sure your phone is UNLOCKED and that it can be used abroad. If you can’t get your phone unlocked to use with a SIM card abroad, you could still get connected to WiFi at the hotels and cafes locally.

In Vietnam, there are 4 major network providers. You can search for their official carrier store’s closest location from their websites on where to buy a SIM card in Vietnam.

No contract is required. Bring your passport to register. The SIM is valid until your visa’s length of stay.

At the back of the card, you should find a box like the one marked by the red rectangle in the above picture. That is the part contents a series of numbers you need to input to top up your account. It should be properly covered with no sign of damage or scratch. You should also look for the expiry date of the top up card (underline part in the picture).

After scratching the opaque covering to review the numbers, open the dial pad on your phone, input the following code *100*[Series of numbers beneath the covering]#, then hit the call button. You will usually receive a notification through SMS that states the top up is successful and information of your account (the balance, expiry date, and balance of promotion accounts, etc.). You can also check the balance of your account by input the code *101#. A pop-up notification will appear on screen with all information of your account.
