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 Former CDMA-operator S-Fone has gone bankrupt and its license was revoked.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 after Viettel, Vinaphone, Mobifone and Gmobile received licenses in 2016.

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.

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 2017? 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.



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 over 25,000 base stations to almost 95% of the country giving it the best 4G coverage 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.

4G/LTE Edit

For 4G/LTE, be sure to get one of their new 4G-enabled SIM cards. Old 3G SIMs can be swapped for free in their stores until June 2017. As an ongoing promotion from March 2017 Viettel gives 10 GB when you get a new 4G SIM or swap a 3G to 4G SIM. You need to text '4G' to 191 to get the bonus.

Data feature packages Edit

Data on 3G is up to 21.2/5.76 Mbps, 4G/LTE is only slightly faster. You may need to activate data by texting "3G ON" to 161. Type *101# to check your call balance. Default rate outside of packages is 75 VND per 50 KB by default.

These following monthly packages on 3G can be booked through your device:

All packages auto-renew, if there is credit.To stop auto-renewal, text "HUY" to 191 (then "Y" to confirm), but all packages will be cancelled immediately and the rest of your data volume will be lost. If you use up your high-speed data before your 30 days is up and want to re-subscribe to regain full-speed data, you must first cancel your current subscription (sending "HUY" to 191, then "Y" to confirm) before it will let you re-subscribe.

Tourist SIM Edit

Viettel introduced a tourist SIM for visitors sold mostly at the airports and their big stores. It's sold for US$ 5 or 10 and needs to be added with one of these plans:

Price Data domest. calls interntl. calls Validity

Data-only SIM: Dcom Edit

Their Dcom service is for Mobile Broadband in 3G data-only for any devices. It can be used in smartphones too, but doesn't have voice and text, nor 4G/LTE. SIM cards can be switched from/to Tomato. They sell these 3G data bundles for Dcom only:

Vietnamobile Edit


Vietnamobile is the smallest of the 4 providers and the only one that is privately owned. It gives out the best prices in Vietnam and has a market share of around 10%.

In 2011 they started with 3G services in Ho Chi Minh City, Da Nang and Hanoi, but since then 3G coverage has been expanded to Ba Ria-Vung Tau, An Giang, Khanh Hoa, Binh Thuan, Dong Thap, Long An, Dong Nai, Thai Nguyen and Binh Duong. In 2017 it covers 90% of the population in all 63 cities and provinces by 3G. Coverage is still lower as the state-owned providers and 4G/LTE hasn't started yet. So better make a network scan, before you buy one of their SIM cards.

Availability Edit

In the major towns you have to look for their logo to find an outlet first, as their English online store locator is not working. But, you can try your luck here: [1] Starter kits come in different varieties. Their standard VMOne is for 25,000 VND with 10,000 credit, valid for 30 days. Other kits may be higher with more credit preloaded.

Top-ups are by scratch cards of 10,000, 20,000, 50,000 and 100,000 VND. You get a bonus of 100% for the first 10 recharges of 20k or higher.

Data feature package Edit

You may have to enable 3G data by typing *345#. Default rate outside of package is 75 VND per 15 KB, overuse fee as long as package is still on is 25 VND per 50 KB. They offer these packages or special scratch cards for data:

Data Period Price Activation
1 GB 1 day 3,000 VND D3
300 MB 10 days 12,000 VND D12
100 MB 30 days 10,000 VND M10
2 GB 30 days 40,000 VND M40
4 GB 30 days 70,000 VND M70
6 GB 30 days 90,000 VND M90
10 GB 30 days 125,000 VND M125
20 GB 30 days 200,000 VND M200

They also sell two data scratch cards. These top-ups translate directly into data allowances:

  • 250 MB for 7 days: 9,000 VND
  • 500 MB for 14 days: 20,000 VND

Tourist SIM Edit

In 2016 they introduced a Tourist SIM too. But have in mind that their coverage is not so good for travelling, only when you stay in the main cities. It comes in 2 denominations:

  • Tourist 100: 125,000 VND with 50 mins to USA, Canada, Malaysia, Australia, Singapore, India, S.Korea, Thailand and Hong Kong, 1 GB data per day, unlimited Vietnamobile on-net calls and SMS for 7 days - activation: *699*1#.
  • Tourist 200: 250,000 VND with 120 mins to the countries mentioned above, 1 GB data per day, unlimited Vietnamobile on-net calls and SMS for 14 days - activation: *699*2#.

The SIM must be activated by calling 118 and choosing one of these packages above. Package will be auto-renewed after 7 or 14 days and SIM card will expire 60 days after activation. It can be topped up like any usual Vietnamobile SIM card, but stays on one of these packages only.

Data-only SIM Edit

For 65,000 VND they sell a data-only SIM without text or voice. It comes with 5 GB for 30 days included. You can also convert a regular voice SIM to a data SIM by texting 'DATA SIM' to 345. Only for this data SIM, they offer special packages valid for 30 days:

  • 1 GB: 20,000 VND, activation: DK USB20
  • 5 GB: 50,000 VND, activation: DK USB50
  • 10 GB: 100,000 VND, activation: DK USB100

Text activation code to 345.
