❓ FAQ: Viettel eSIM Data Only for Vietnam
- 🛬 Can I activate my Viettel eSIM at the airport?
Yes! You can scan the QR code and activate within 5 minutes at any airport with WiFi (Hanoi, HCMC, Da Nang, etc.). Free airport WiFi helps with setup if needed. - 🌏 Does it really work everywhere in Vietnam?
Yes for cities/towns, but some very remote mountains or islands may have weaker signal. Viettel is best for coverage. - 🔄 Can I extend or top-up my eSIM?
With GovnSIM or Viettel, top-up is possible (credit card, e-wallet, sometimes Momo/PayPal). Check seller policy before buying. - 📞 Does it support voice/SMS?
No. It’s for data only! All calls/messages via apps (WhatsApp, Zalo, Viber, Messenger, etc.). - 🆓 Is it really unlimited?
No. “Unlimited” plans always have a daily high-speed cap (e.g., 2GB–3GB), then speed drops (to 512Kbps or less). For regular travel, this is enough for maps, chat, email, but not streaming HD after the cap.
