Your ticket to seamless connectivity in Vietnam
Where to buy a SIM card in Vietnam
You can buy a SIM card for Vietnam before your trip or after you land. Either way, there are plenty of options for staying connected. Here’s how to get a SIM card in Vietnam at each stage of your trip:
- Online: You can buy your Vietnam SIM card from international retailers such as Amazon or KKday and pick it up at the airport in Vietnam or have it delivered to your home before the trip.
- At the airport: You’ll find SIM card kiosks by local cell service providers at the Hanoi, Nha Trang, and Ho Chi Minh airports, so you can get connected almost as soon as you land. For a Vietnam SIM card, arrivals at Saigon airport can head to the carrier kiosks at Tan Son Nhat International Airport.
- In Vietnam: If you left the airport without your Vietnamese SIM card, you can get one at official stores throughout the country, as well as convenience stores such as Circle K, 7-Eleven, and Minimart.
- Buy an eSIM: You don’t need a physical SIM card if you are after a Vietnam data SIM card. You can get an international eSIM instead and enjoy instant connectivity whenever you need it. It only takes a couple of minutes to buy, set up, and activate your eSIM, all you need is internet access and an eSIM-compatible phone.
How to register your Vietnam SIM card
SIM card registration is mandatory in Vietnam for both locals and foreigners — a policy introduced in 2016 to prevent misuse of unregistered SIM cards for illegal activities. The store workers will help you through the registration process when buying your SIM, but you will need to provide a valid passport and an unlocked phone at the store.
Once your SIM is registered, you’ll still need to activate it before it starts working. Here’s how you can do that:
- Insert the SIM card into the SIM slot in your phone
- Turn on your phone
- You will receive a text message with activation instructions from your SIM provider
- Follow the instructions to activate your SIM card
- Get a top-up for your SIM to start using it
If you’d rather skip the lengthy registration process, get an eSIM for Vietnam instead. Holafly doesn’t require you to register or provide your ID, simply buy your eSIM, activate it, and enjoy instant connectivity.
