From the moment you land at a Vietnam airport, to the hotels/hostels or souvenir shops, local grocery stores, it is an effortless thing to do.

However, it is no longer the case now since the Vietnamese Government has reinforced the law recently.

As a result of new law in Vietnam, it is advisable that you buy SIM card directly at the providers’ official stores. Then, the staff can support you with the registration process which might take only from 5 to 10 minutes. In this process, travelers do not need to sign any contract or term, just simply register your information. In fact, SIM cards are not forbidden to sell outside regardless of the strict rule of using it; as many sellers can pre-register the SIM card with someone else’s identity. These pre-activated SIMs can be used but they are likely to be shut down any time because it is not officially signed up. Hence, if you buy SIM from unofficial places, make sure it is already in use. Otherwise, find a nearby mobile supplier store to do the registration.

Mobifone Vietnam

Mobifone is the third largest mobile supplier. Still, this provider is less preferred compared to Viettel and Vinaphone as a result of not so stable connection in rural areas. If you only need your phone to stay connected in big cities, Mobifone is still a good option. Otherwise, you should not consider this as a priority. 

They provide tourists with a special SIM which is called “Happy tourist” with the price 200,000VND. When using this package, you will be offered up to 70 minutes of call, 30 SMS to either local or international numbers and 3GB of data with validity up to 60 days


Vietnamobile is the smallest operator in the list. It offers strong connection in big cities but struggles in rural area.

They also have tourist SIM you can easily buy, for 65,000VND (data only with 5 GB valid for 30 days), 125,000VND (50 minutes of international call, unlimited Vietnamobile on – net call and SMS for 7 days) and 250,000VND (120 minutes of international call, unlimited Vietnamobile on – net call and SMS for 14 days.
