Does the A series support eSIM in Vietnam?
No — no eSIM hardware
The A series has no eSIM hardware, so a Vietnam eSIM will not work on it. Use a physical Vietnam SIM instead — pick one up at the airport on arrival or have one delivered to your hotel. You still get the same daily high-speed data.
No eSIM? No problem
Grab a cheap physical SIM at Noi Bai (Hanoi) or Tan Son Nhat (HCMC) airport, or have one delivered to your hotel — same data plans, no eSIM required.

5GB/day from $8. Buy direct from an authorized Viettel & Vinaphone dealer — cheaper than global resellers, and the Vinaphone plan even gives you a real +84 number for OTP and Grab.
