Viettel, Vinaphone and Mobifone cover cities and QL1 highway on 4G and 5G; Ha Giang loop remote passes, Mekong delta floating markets and some central highland tracks fade. Hanoi and HCMC metros expand with partial underground coverage. When you use NXTL in Vietnam, your phone attaches to local networks such as Vinaphone, Viettel; the live table on this page is the current list.
Prepaid SIMs are sold at airport kiosks and phone shops with passport registration; tourist eSIM QR codes are common at arrivals. Local numbers help with Grab, Gojek and WhatsApp homestays. NXTL is the lower-friction option for most visitors to Vietnam. You are not shopping for a SIM in Ho Chi Minh City after a long flight — the eSIM is already on your phone, billed pay-as-you-go, with credit that carries to your next destination.
Setup takes minutes at home. For Vietnam, install NXTL while you still have reliable Wi-Fi, keep your home line active for calls and bank texts, and switch on eSIM data when you land (for example via Tan Son Nhat (SGN)) so you can navigate straight to Ho Chi Minh City. Top up later if you need more; unused balance stays yours.
The reason travellers choose NXTL for Vietnam — and for trips that do not stop there — is continuity. One eSIM, pay-as-you-go pricing, no expiry, and no new SIM when you leave Ho Chi Minh City for the next country. Your leftover credit is still waiting.
Reunification Express overnight berths between Hanoi and Da Nang pass rural stations where only Vietnamese announcements play unless you have translation ready on mobile data. That is where NXTL helps in Vietnam: one eSIM ready before you arrive, billed only for the data you actually use.
