Best eSIM for Vietnam 2026 — What you need to know
Staying connected while visiting Vietnam has never been easier. Instead of hunting for a local SIM card on arrival or paying expensive roaming charges, you can purchase an eSIM before you even leave home and have mobile data ready the moment you land. Browse our latest eSIM deals for Vietnam above to find the best plan for your trip.
When choosing an eSIM for Vietnam, consider how long your trip is and how much data you'll realistically need. Vietnam trips typically need 3–5GB for a week — Grab (ride-hailing), maps, and social media are the main data consumers.
Vietnam has rapidly improving mobile coverage from Viettel, Mobifone, and Vinaphone. 4G coverage is strong in Hanoi, Ho Chi Minh City, Da Nang, and Hoi An.
We recommend purchasing and installing your eSIM while still connected to WiFi at home, ideally the day before you travel. All plans listed above link directly to the provider's website where you can complete your purchase securely. Grab is essential for getting around Vietnamese cities. Having mobile data from an eSIM means you can book rides immediately on arrival.
