SIM Cards at SGN
One of the first things you'll notice at Tan Son Nhat International Airport is the SIM card kiosks near baggage claim.

Key considerations for pocket WiFi:

Coverage & Reliability in Ho Chi Minh City and Beyond
The primary mobile network in Vietnam is Viettel.
Signal quality in major urban centres like Ho Chi Minh City is excellent, with fast and reliable 4G/LTE speeds.
Outside of the main cities, coverage can become less consistent. Viettel is generally considered to have the most extensive network, making it a reliable choice if you plan to travel to more rural or regional areas.
