Comparison
Provider fit for Vietnam
HelloRoam — our top-rated pick — routes Vietnam plans through Viettel, the highest-coverage Tier-1 network in the country, delivering 5G at $1.37/GB. Vietnam mobile data prices are among the lowest globally — local prepaid costs 80% less than airport eSIM purchases. Airalo offers Vietnam plans through both Viettel and Vinaphone, making it the stronger choice when network redundancy matters — particularly in rural areas where Viettel coverage thins. Holafly covers Vietnam with unlimited daily plans from $4.43/day. It is the correct pick for travelers streaming video, taking video calls, or tethering a laptop — scenarios where a fixed data cap creates daily anxiety. Local Viettel SIM costs $3 for 6GB/30 days — the cheapest in Southeast Asia, but registration hassle adds 20 min.
