A few details that help before and during your trip.
Mobile coverage in Vietnam
Vietnam's mobile network is served by three main operators: Viettel, Mobifone, and Vinaphone. 4G LTE coverage is strong across Hanoi, Ho Chi Minh City, Da Nang, and all major cities, with reliable connectivity along the coastal highway, main rail corridors, and popular tourist routes. Ha Long Bay has coverage on cruise boats and in Ha Long City, with signal varying on the water depending on distance from shore. Phu Quoc Island has reliable coverage in resort and town areas. The northern mountain provinces including Sapa, Ha Giang, and remote ethnic minority villages have coverage in main towns with signal weakening on trekking routes and in high mountain terrain. The Central Highlands and remote border areas near Laos and Cambodia may have more limited infrastructure. MobiSIM connects through supported Vietnamese networks to deliver reliable data across the country's main cities and tourist destinations.
