Which mobile networks does Vietnam have?
Vietnam's 5G reached 90% of the population by February 2026, with close to 40,000 base stations installed and about 23 million 5G subscribers.
- Viettel: Viettel, run by the military, is the largest operator with the widest rural and mountain coverage, over 30,000 5G stations, and Vietnam's only fully standalone 5G network.
- Vinaphone: Vinaphone, the VNPT brand, has posted the fastest average download speeds at around 31.8 Mbps and performs strongly in Hanoi, Da Nang and Ho Chi Minh City.
- MobiFone: MobiFone is the third national network with solid city coverage but a thinner footprint than Viettel once you leave urban areas.
A handful of MVNOs resell the main networks, but tourist SIMs and travel eSIMs almost always run on Viettel, Vinaphone or MobiFone.

Is 5G available in Vietnam?
Viettel has the widest 5G, with 90% outdoor coverage and a target of 98% of the population during 2026, while VNPT is expanding on newly licensed 700 MHz spectrum from mid 2026.
How much data do you need in Vietnam?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in Vietnam right now:
eSIM or a local SIM at the airport in Vietnam?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter. Data for Vietnam starts at $9.63 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your Vietnam eSIM
Buy your planYou get a QR code by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Airport and hotel wifi can be weak.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to find the network.
Check the validity clockSome plans start counting at purchase, not at first use. Check before you buy.
Good to know before you land in Vietnam
Physical SIMs must be registered in person with your passport at official carrier stores, which takes 10 to 20 minutes. eSIMs bought before arrival skip the paperwork.
Viettel, Vinaphone and MobiFone counters at Tan Son Nhat sell tourist SIMs for roughly 200,000 to 400,000 VND, about 8 to 16 dollars. Viettel's TOUR200 package at 200,000 VND gives 5 GB per day for 7 days plus calls.
For Ha Giang, Sapa, Cao Bang or anywhere in the northwest mountains, Viettel is the safe choice. Its 4G reaches valleys where the other networks drop to 3G or nothing.
