Viettel has the most consistent coverage in the highlands. On the passes and farm roads the other networks drop out and Viettel does not.
Cần biết trước. 7 days is 60k, 15 days is 80k. Passport registration is legally required for a physical SIM — buy at an official store, not a phone stall, and skip the airport kiosks which charge 20–30% more. eSIM from resellers usually needs no passport.
