Mobile coverage in Vietnam
4 carriers support Best Global eSIM plans in Vietnam. Tap any operator below to see their official coverage map.
Vietnamese SIMs are sold at convenience stores but require passport registration with a Vietnamese-only flow — fine if you've got time, frustrating after a Tan Son Nhat arrival. An eSIM skips it: you're on Grab and Google Maps the moment your phone wakes up.
Networks: Roams onto Viettel, Vinaphone, and MobiFone. Viettel has the strongest signal in remote northern mountain areas (Sapa, Ha Giang) and central highlands; Vinaphone tends to be fastest in Saigon and Hanoi.
