Where to buy SIM card in Vietnam + Registration?

You can buy SIM cards almost everywhere – at the airports, in the official stores, in the big cities, in the small towns, in Hanoi almost everywhere… To buy a prepaid SIM card, you have to officially show your ID or passport and need to be registered first, before the SIM card can be activated. But in practice, this was not really much enforced before November 2016. Then the government shut down 12 million falsely registered SIM cards (more information).  The rules are now more strictly enforced, that you bring your passport and register to activate your SIM card in an operator’s store.

Official registration can be done in the major stores of the operators.

Small independent street shops can’t activate them for you and they still sell a SIM on somebody else’s identity to you. With these vendors make sure that they activate it for you or show where and how to do it. Official registration can done in the major stores of the operators or the seller will direct you to a registration point, where you’ll need to show your passport. Don’t leave the store without instructions, how to activate or with a SIM which is already activated. You can check whether your SIM has been registered by texting ‚TTTB‘ to 1414 on all major operators. If registered, the response will include the name, birthdate, and ID number (Vietnam ID or foreign passport) of the registered individual.

icon-angle-double-right RECOMMENDED from 2017 – buy and register your Sim card at the major store of mobile operator.

A traveller visiting the country for only a few days may do fine without registration. You only risk that your SIM will be shut off anytime without prior warning. This has been reported after 4 days already. To avoid losing your credit and allowances in this case, you’ll need to go to a registration point in an official store and re-register your SIM on your name by showing your passport as required by law. If you want to call in Vietnam withou any problems – go the official store.

I had a Viettel SIM card with 3GB data package for 3G internet for 1 month and I paid 250,000 dong. It was enough for a whole month. I made some local calls, and almost every day I used Google Maps, and email and occasional surfing the internet. In some remote mountainous areas there may not be a signal, but I only had a problem once on the route between Lai Chau and Son La city. In some areas you may have a problem with roaming. For more information, you need to contact your mobile operator.
