This guide compares Viettel, VinaPhone, and MobiFone coverage, updated 2025 SIM prices, and convenient eSIM alternatives.

🛵 Case Study: Traveler Experience in Ha Giang
Tom, a traveler from Germany, visited Ha Giang in February 2025:
- He arrived on the early morning bus and found shops near the terminal quoting 550,000 VND (~$22) for a Viettel SIM with 30-day data.
- Fortunately, he had purchased a Viettel eSIM online for $16.90 before departure.
- His eSIM activated instantly, allowing him to book a motorbike and navigate directly to his hostel.
- During the loop, he always had service with Viettel, while his friends using MobiFone lost signal multiple times between Yen Minh and Dong Van.
His takeaway: buying offline was not only more expensive but also inconvenient, while Viettel remained the most reliable provider in the region.
🗺️ Connectivity Tips for Remote Routes
- Download offline maps (Google Maps or Maps.me) before leaving Ha Giang City.
- Save homestay and emergency contacts in your phone.
- Carry cash, as ATMs and card readers are unreliable in villages.
- Consider a dual-SIM phone if you want both Viettel and VinaPhone for backup.
🔋 Battery & Data Saving Tips
- Enable Low Power Mode during long rides.
- Turn off background data for non-essential apps.
- Bring a 20,000 mAh power bank — charging points are rare outside towns.
- Download playlists and translation apps offline to reduce data use.
✅ Final Recommendation
If you want the best network in Ha Giang, Viettel is the clear choice for coverage across mountain passes and remote districts. VinaPhone and MobiFone perform reasonably well in towns but cannot match Viettel in the countryside. Offline SIMs in Ha Giang often cost 30% more than eSIMs, so pre-ordering an eSIM ensures lower cost, instant activation, and full connectivity from the moment you arrive.
