How To Get Your Vietnamese SimCard

Getting a Vietnamese Simcard can be incredibly confusing for a tourist. Here is an up to date guide to show you everything you need to get yourself a Vietnamese Simcard in the right way.

In November 2016, the Vietnamese government started enforcing registration rules for local SIM cards and canceled 12 million cards that had been illegally registered. As a result, travelers are now advised to only purchase SIM cards from official carrier stores, where they will need to show their passport to register the card.

If you purchase your SIM card from a vendor who cannot register your SIM card for you, it means that you’re either buying a pre-activated card which can be shut down at any time or an unregistered card that will require a trip to an official store before it will work.

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.

Staying connected in Vietnam is quite cheap — just from 5 to 10 USD will keep the data flowing on your smartphone throughout your stay.

Here’s what you need to know.

1. Vietnamese Carriers

There are four major cell networks in Vietnam. Viettel has the largest network and most customers, closely followed by Vinaphone and Mobifone, the least popular one is 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 Former CDMA-operator S-Fone has gone bankrupt and its license was revoked.

We recommend Vinaphone for most travelers due to price and convenience.

Viettel removed roaming charges in Laos and Cambodia in early 2017.  So you can use Viettel SIM card if you want to use the same SIM in three countries. Viettel is also considered as the best choice when you are going to rural areas

Avoid Mobifone if you’re heading off the beaten track, and there’s really no reason to go with Vietnamobile — it’s the cheapest of the lot, but has very poor 3G service outside the largest cities.

2. How should you get your SIM Card

No matter which carrier you choose, you should always purchase your SIM card from an official store. You can find your nearest official stores here (There is no English list but it’s quite simple and the only information you need is the store address)

Viettel Official Store in Ha Noi

Viettel Official Store in Ho Chi Minh city

Vinaphone Official Store in Ha Noi

Vinaphone Official Store in Ho Chi Minh city

I myself purchased my Vinaphone card from a large official store in Hanoi’s old quarter.It took around ten minutes but was quite straightforward. The salesperson showed us the various prices on a piece of paper, we chose one and handed over a passport and some cash, and she dealt with the rest. The process is likely to be the same in other outlets.

3. Data feature package


Data feature packages

You may need to activate data first by texting “GPRS ON” to 888. Speed on 3G is a max of 14.4 Mbps. Default data rate outside of packages is 1.5 VND per KB.

All packages auto-renew, if there is credit.To stop auto-renewal, text “HUY” to 191, 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) before it will let you re-subscribe.

Tourist SIM

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 Domestic calls International calls Validity
100,000 VND 1 GB 20 mins 10 mins 5 days
200,000 VND 2 GB 40 mins 20 mins 10 days
300,000 VND 3 GB 60 mins 30 mins 15 days
500,000 VND 5 GB 100 mins 50 mins 25 days


International calls are to 25 countries only. Both mobile and landline: USA, Canada, China, Hong Kong, Thailand, Singapore, South Korea;

Data overage charge is 9.76 VND per 50 KB.

One thing to note is that the Tourist SIM does not include SMS texting. To add texting, you need to add a scratch off card to the account to pay for SMS messages.

To check account balance *101# (free), to check remaining data capacity, USSD Code: *102#(free)

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. SIM cards can be switched from/to Tomato. They sell these data bundles for Dcom only:

Data Time Price Activation
2.5 GB 30 days 30,000 VND D30
3.5 GB 30 days 50,000 VND D50
5 GB 30 days 70,000 VND D70
7 GB 30 days 90,000 VND D90
10 GB 30 days 120,000 VND D120
20 GB 30 days 200,000 VND D200
4 GB/month 6 months 300,000 VND DC300
5 GB/month 12 months 500,000 VND DC500


Daily packages will renew every 30 days until out of credit. DC10 is the default package when no other bundle is booked. Packages are hard-capped with 9.76 VND per MB overuse fee.

To activate, text the name of the bundle to 191. All bundles auto-renew. To stop text “HUY” to 191, to check balance text “HTTK” to 191. The same daily add-ons as mentioned above can be added.

Topping Up

It’s very easy to top up your credit. You can buy credit pretty much anywhere you’re ever likely to go as a tourist. Language barrier shouldn’t be a problem because most of those stores just sell cards and top-ups only, and besides, they’ll be in a glass case, so you can just point and wave your phone about.

If not, you just type *100*<code on the top-up card># to add the credit, then send an SMS to 888 to activate the call/data package you want to use.

Coverage and Data Speeds

Speeds depend on where you stay. Places like Hoi An, with less network congestion, download speeds can be close to 10Mb/sec.Those speeds dropped by roughly half in Hanoi and Saigon, and it’s very hard to get data service at all when the weather is bad.

You should be able to have full Vinaphone and Viettel 3G signal anywhere in and around Hanoi, Saigon and Hoi An.

That’s it! Hopefully you should be all set to use maps and social media during your trip. Have fun, but take your eyes off your phone once in a while.
