Vietnam eSIM Networks: Viettel vs. Vinaphone

Voye Global’s Vietnam eSIM connects to Viettel (5G, 4G, 3G) and Vinaphone (4G, 3G), the two largest mobile networks in Vietnam. Viettel has the widest reach across the country, including rural and mountainous areas, which makes it a strong option if your trip goes beyond the main cities. Vinaphone covers Vietnam’s cities and the most popular tourist routes reliably, though its reach narrows outside urban areas.

Your eSIM switches automatically between these networks based on signal strength, so there’s nothing to configure manually. Whether you’re in Hanoi’s Old Quarter, a rooftop bar in Ho Chi Minh City, or further out toward Sapa, your phone connects to whichever network gives you the best signal at that moment.
