Travel tip:
Mobifone is a stable, reliable choice for almost every trip in Vietnam, with over 20% of the population using this network and excellent coverage in cities and tourist hotspots.
However, if your itinerary includes mountain, remote, or border areas like Sapa, Ha Giang, Cao Bang, or the Central Highlands, we strongly recommend Viettel eSIM for the most reliable coverage. Viettel is the only network trusted by locals and trekkers for a strong signal in every province of Vietnam.
