Basics Edit

There are 4 major GSM network operators in Vietnam:

  • Viettel
  • Vinaphone
  • Mobifone
  • Vietnamobile

Two other providers not on the list are Gmobile (formerly Beeline), operating only on 2G so far (they received a 4G/LTE license in 2016, but haven't started yet). Former CDMA-operator S-Fone has gone bankrupt and its license was revoked.

Coverage and speeds are quite good for SE Asian standards: 2G/GSM is on 900 and 1800 MHz, 3G on 2100 MHz. Viettel and Vinaphone introduced DC-HSPA in 2014, 4G/LTE is just being launched on 1800 and 2600 MHz (bands 3 and 7) after Viettel, Vinaphone, Mobifone and Gmobile received licenses in 2016, Vietnamobile in 2017. The three state-owned operators aim to increase 4G/LTE coverage to 95% each in 2019.

According to OpenSignal report in March 2019 4G/LTE availability is between 65% of Vietnamobile and 86% of Viettel which also tops the speed list at 17 Mbit/s download and 6 Mbit/s on average.

In March 2015, a new numbering plan was introduced and all 11-digit mobile numbers will be shortened to 10 digits. As prices are more or less ruled by the state, there is in fact not much competition going on between the operators and rates are pretty much the same amongst them.

Vietnam is planning to close all its 2G networks in the country by 2022.

Regulations Edit

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. The rules are now more strictly enforced, that you bring your passport and register to activate your SIM card in an operator's store. Small independent corner 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.

So what is a visitor to do in 2018/9? Edit

You can still buy a SIM card at a corner store or at the airport. But have in mind that they are not properly registered. Even at airport booths, they still sell them without the legal registration. When you ask for it, they will smile or find an excuse or simply lie to you.

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 continously need mobile data, travel through the countryside where there are no registration points and/or stay for longer, it's now very much recommended to go the legal way by buying and registering your SIM card in a major store of an operator.

Where to buy a SIM card at Ho Chi Minh City’s international airport Edit

  • Tan Son Nhat airport is the main international airport in HCMC
  • Getting a SIM card there is very convenient. You can get it either before you go through passport control or after. You should getting it AFTER you’ve got your bags and left the customs area, because the desks before passport control are not official sellers and many people report the SIM card stopped working after 12 hours
  • Also, only the international terminal has SIM cards. If you arrive in the domestic terminal (which is in a separate building), you won’t be able to buy a card there
  • Where to find the SIM card vendors at the international terminal:
  1. Pick up your bags and exit the customs
  2. Turn left and walk towards the end of the building
  3. After walking just 80 meters or so at the very end of the terminal building, you will see on your right hand side you see a [SASCO Travel] SIM cards couter. SASCO Travel sells all type of sim including 3 largest telecom companies in Vietnam: Viettel, Mobifone, and VinaPhone
  • Opening hours of these offices: 7am to 2:30am daily. You can also purchase the SIM online through website and pick up at the counter to save time.
  • How much does a SIM card cost:
  • Please visit here to find out details info:
  • To buy a card you need to have cash Dongs, which you can get in one of the nearby exchange booths. The exchange rate at the airport is basically the same as the city



Viettel is owned by the Ministry of Defence and thus the Vietnamese army. It's the market leader in Vietnam with about 40% of all customers on its network.

It has the best coverage in remote places even on 3G. 4G/LTE was officially launched in April 2017 on 1800 MHz (B3) over 25,000 base stations in almost 95% of the country giving it the best 4G/LTE coverage in the country for now.

As prices don't differ so much between the 3 major operators, Viettel should be your first choice when you are going to rural areas.


SIM cards are available at the airports and lots of shops in town. Recharge cards are widely available in small shops and on the sidewalks. Shop staff is usually happy to try to help when adding credit, even if they don't speak a word of English. Best option is to visit a Viettel store in a bigger city. They speak some English and prepare everything for you, even cutting to nano SIM. SIM cards are around 50,000-60,000 VND depending on number with some credit.

Their prepaid brands are called Tomato and Economy and don't come with data. So you have to book a package. Balance check is *101# for main account and *102# for bonus account. To top-up by voucher, type *100*<voucher PIN>#. The vouchers can be aquired all around town, just look for the Viettel logo. Be aware that Viettel sends a lot of advertising SMS.

Call 191 to get balance or top up through the voice system. You can switch to English by pressing 3 (entering the language menu), second menu press 2 (select English), third menu press 1 to confirm.

To keep Viettel sim card alive is very easy, just do any activity which deducts some amount of your balance every 60 days. Or another choice is sending VTVANG to 109 before you leave the country. This costs you 50.000 VND but it keeps your card safe for 365days with no worries.
