Viettel eSIM for travellers to Vietnam
Vietnam's largest carrier — the strongest, widest coverage, including remote highlands and islands. Every plan comes with 5GB of high-speed data per day — just pick the length that fits your trip: 7 / 15 / 30 days.
Which duration should you pick?
- 7 days — short trips, city breaks or quick business visits.
- 15 days — longer holidays or multi-province itineraries.
- 30 days — extended stays, cross-country travel or long business trips.
Why choose Viettel?
- Instant QR activation — no physical SIM, no shop queues.
- Keep your home number so you still receive OTPs and calls.
- 5GB/day on 4G/5G — plenty for maps, video calls, social media and ride-hailing.
- Hotspot sharing for your laptop, tablet or travel companion.
- eSIM + QR emailed instantly after payment, so you can set it up before you fly.
Coverage
Viettel reaches almost every province and stays reliable off the beaten track — the safe pick if you're heading to Ha Giang, Sa Pa, Da Lat, Ninh Binh or islands like Phu Quoc and Con Dao.
Set up in 2 minutes
- Check your phone supports eSIM (iPhone XS or later, most recent Android).
- After purchase, open the email from BellRoam for your QR code.
- Go to Settings > Cellular/Mobile > Add eSIM and scan the QR code.

Tip: install the eSIM at home over Wi‑Fi, but only switch data on after landing so your days start when you actually need them.
