Stay Connected in Vietnam 2026: Fast 5G eSIM Guide
Quick Pick: In Vietnam for a week? Get Saily for peak 5G speed.
Vietnam is a land of stunning contrasts, from the buzzing motorbikes of Ho Chi Minh City to the limestone karsts of Ha Long Bay. In 2026, the best way to navigate this landscape—and its digital-first economy—is with a high-speed 5G eSIM. Skip the long queues at Noi Bai or Tan Son Nhat airports. Avoid the complicated mandatory facial registration required for local physical SIM cards. With Saily, your Vietnamese adventure starts the moment you land.
Vietnam moves fast between crowded cities, coastal routes, and mountain roads. GoSimo currently recommends Saily because it switches between Viettel and Vinaphone, keeps hotspot fully usable, and stays much simpler than buying a local SIM after landing.

Why Saily
Why Saily is the #1 Choice for Vietnam
Vinaphone for city speed
Vinaphone helps keep Hanoi, Ho Chi Minh City, and Da Nang fast, which is especially useful for Grab, uploads, and routine travel tasks in dense urban areas.
Real speed profile
5G in bigger cities usually lands around 100-150 Mbps, while rural 4G commonly stays in the 20-40 Mbps range. Latency is often around 60-90 ms, which is fine for Zoom and travel apps.
Full hotspot freedom
Saily officially allows Personal Hotspot and does not report a separate tethering cap. If you buy 20GB, you can use the full 20GB across your laptop and other devices.
