Telco providers in Vietnam
There are four main telco providers in Vietnam: Viettel, Vinaphone, Mobifone and Vietnamobile. Locals and travelers use SIM cards from all four networks, and they can be trusted whatever plan you choose. According to OpenSignal’s coverage map, Vietnam has a good or above average signal for South-Eastern Asian standards. Coverage can suffer in the remote country regions, but that will happen on any phone or provider you use there.

Some top tips from finder.com staff:
- The official language is Vietnamese. Not many locals speak English, so download Google Translate onto your phone before you travel if you need help with the language.
- Locals call a SIM card a “Chip” or “SIMkaa”.
- Ask the sellers to set up the SIM for you, because they will know how to do it. If not, follow the instructions we have highlighted above or go to the official operator website to get advice.
- Get to the shops early to receive better assistance and avoid the crowds!
TripAdvisor tips for the best SIM cards and where to buy them
While it’s well known for reviews, booking hotels, flights and holidays, TripAdvisor also has many user comments that can help guide you through which SIM cards have been tried and tested in Vietnam.
Here are some top tips from TripAdvisor users:
“In the big cities, Mobifone is always recommended to use, but if you will travel to remote areas, VIettel is the best one.”
“The Vietnamese Internet setup is not particularly fast when it comes to Internet surfing, unless your target pages are located in Vietnam. And, there’s no “high speed” mobile Internet.”
“You will be able to buy SIM cards at nearly every shop. If Nano SIM cards are needed they will cut it accordingly.”
“If they don’t have a micro sim they use a cutting press to create a micro SIM card out of a standard SIM.”

More questions?
Q: Is the signal really that bad in the countryside?
A: All networks will suffer in the countryside, no matter what provider you use. Vietnamese networks offer a relatively reliable service that is no worse than what you would get on your home phone there, so it makes sense to opt for a local SIM card because the rates are reasonable.
Q: What should I do if I lose my phone?
A: Your phone is your lifeline, especially when traveling around Vietnam. Make sure you keep it safe and always make a note of where it is. The importance of having a direct link to family and friends via social media or through phone services can never be underestimated! If you do lose your phone, then retrace your steps and ask around. If you don’t have any luck, then report it missing. Finally, find a cheap replacement to keep in touch with the outside world, and don’t let this one out of your sight!
