From Hanoi, Ha Long Bay, Hoi An and Ho Chi Minh City, Vietnam is a country you cross rather than sit still in — and you need data the whole way.
Network coverage in Vietnam
Our Vietnam eSIM connects to the local Vietnamobile and Vinaphone networks, so you get 5G and 4G data on the same masts residents use. Coverage is strong along the coast and the main north-south route; Ha Long Bay cruises lose signal offshore. Sleeper trains between Hanoi and Da Nang keep a signal along most of the coastal line.
How much data do you need?
Budget 500 MB to 1 GB per day for maps, messaging and the occasional video call. If you plan to navigate continuously or work on the road, unlimited works out simpler than topping up.

Setting up your Vietnam eSIM
Setup takes about two minutes: your QR code arrives by email straight after checkout, you scan it before you leave, and the plan activates when you land in Vietnam. No physical SIM, no queue at the airport, and your usual number stays active for calls and texts.
It suits short city breaks as much as long stays: tourists comparing routes on the move, business travellers who need a stable connection between meetings, and remote workers who cannot afford to lose access on arrival.
A prepaid Vietnam eSIM with no subscription and no roaming bill waiting at the end of the trip.
