Where is the best place to buy a SIM card in Vietnam, at the airport or somewhere else?

This is an individual question, it's up to you. It is convenient to buy a SIM card at the airport because you won't have to study tariffs in advance, then set up your phone after purchase, and it's also convenient that you will have internet immediately upon arrival in the country, and you can order a taxi or transfer, contact the hotel, etc. But the downside is that you will have to overpay at least twice as much as if you buy a SIM card at a mobile phone store. Another problem is that SIM cards at the airport, as well as in most travel agencies, are sold already activated and registered to another person. This means that you won't be able to use it for a long time, because at any moment its 'owner' can contact the mobile phone store and restore it, and your SIM card will stop working.

These problems and disadvantages will not occur if you buy a SIM card at an official mobile phone store of one of the telecom operators with registration using your international passport. It will be both cheaper and safer for long-term use. But the downside is that you will have to spend at least an hour looking for an official mobile phone store and getting the card registered. Moreover, mobile phone stores are not available at all resorts; you will have to search for them.
