Basics[]
There are 4 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 Former CDMA-operator S-Fone has gone bankrupt and its license was revoked.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 SEA 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 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. Generally, Viettel has the best coverage, followed by Vinaphone, Mobifone and Vietnamobile the least.
In 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 to switch off all its 2G networks in 9/2024.
SIM Registration[]
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 strictly enforced before 2016. Then the government shut down 12 million falsely registered SIM cards. The rules are now much more strictly applied, that you need to bring your passport and register to activate your SIM card in an official outlet of the provider. Small independent corner shops can't activate it for you and they may sell a SIM card on somebody else's identity to you. Sometimes this can be hard to tell, but you can check it (see below).
With these street 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 still buy a SIM card at a corner store in town or at the airport. But have in mind that they some of are not properly registered. Even in some 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 traveler 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 a few days already. There will be no other fine. 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 real name by showing your passport as required by law.
If you continuously 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.
Checking registration[]
If you are unsure, where your SIM card has been properly registered, you can text 'TTTB' to 1414. This works with any local provider. You should receive an SMS in Vietnamese with your full name, date of birth (in DD/MM/YY format), passport number and possibly place of issue and an subscriber number of the operator. If these data don't match up or you get a totally different result, you should go to a local operator store with your passport and have it registered, so that it will not be shut off.
5G is available with Vinaphone at major city centres. Viettel does not provide 5G service for tourists who purchase SIM for short term use. However in terms of real world speed, Viettel's 4G/LTE can achieve >100Mbps.
Vietnam's SIM data balance is usually counted per day and reset every day at 0:00hr, and over-use on any day will cause data to be cut off until the quota is reset at midnight.
Most of data plans stated below are out of date.
Kiosks at HAN and SGN airports will try to sell you seemingly attractively priced 4G SIM with data/voice packages, they are pre-activated using local Vietnamese ID and WILL not have the purchaser's name registered in the telecom system, despite what the tout might be telling you. This means the SIM is liable to being blocked, for example, on certain e-commerce apps/ websites when you try to bind your SIM number to your account. Such has happened to this contributor and had rendered the SIM essentially useless, despite having data allowance.
Upon searching for Viettel or Vinaphone many top results are not actually from the official company website, rather some kind of reseller (e.g. 4gviettel.vn, dangkyviettel.com.vn, 5gsimviettel.com, viettelnet.vn etc).
The true company websites are: www.vietteltelecom.vn (note without .com) and www.vinaphone.com.vn.

Viettel[]
Viettel is owned by the Ministry of Defense and thus the Vietnamese army.
It's the market leader in Vietnam with about 60% of all customers on its network.
It has the best coverage in remote places even on 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.
Availability[]
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. Type *101# to check your call balance.
Most convenience stores (including Seven-11 and Winmart) sell scratch-off vouchers.
Buy the desired amount and load it onto your phone by *100*{voucher-code}# and press enter.
To keep a 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 365 days with no worries.
