Why You Need a SIM/eSIM in Vietnam
Internet access in Vietnam is fast and affordable, but you’ll need a local SIM card or eSIM for smooth navigation, online bookings, and ride-hailing apps like Grab. Free WiFi is available in hotels and cafes, but coverage is inconsistent when traveling between cities.
Best SIM Card Providers in Vietnam
Vietnam has three major mobile operators offering strong nationwide coverage:
- Viettel – Widest coverage, especially in rural areas. Best for long-distance travelers.
- Vinaphone – Strong coverage in cities and popular tourist destinations.
- Mobifone – Affordable data plans, good performance in urban areas.
👉 Recommendation: Viettel is the safest choice for tourists who want consistent coverage across the country.
eSIM Options for Vietnam Travelers
Tourists can now use eSIMs to avoid buying a physical SIM card:
- Airalo – Easy purchase via app, data-only plans starting from 1GB.
- Nomad eSIM – Flexible plans for short or long stays.
- Local eSIM (Viettel, Vinaphone) – Available but requires registration at official stores.
📌 eSIMs are best for travelers with newer phones (iPhone XR+, Samsung Galaxy S20+, Google Pixel 4+).
Where to Buy SIM in Vietnam
You can buy SIM cards in two main places:
- Airport counters – Convenient but slightly more expensive. Staff speak English and handle registration.
- City shops – Cheaper options, but may require local help for registration.
💡 Tip: Buy at the airport for hassle-free setup if it’s your first time in Vietnam.
