🗻 Fansipan Coverage
Coverage on Fansipan varies by provider. Field reports in 2025 confirm:

🚉 Buying SIM at Lào Cai Station
While convenient, buying SIMs directly at Lào Cai station is the most expensive choice. Vendors often quote 500,000–600,000 VND for packages that are available online for much less. Registration issues can also lead to deactivation after a few days. 👉 Read more: Lào Cai Station SIM Guide 2025.

For trekkers, stable connectivity is critical. Based on traveler reports in 2025:

- 🔋 Bring a 10,000mAh+ power bank.
- 📡 Viettel offers the widest trekking coverage; make sure at least one member of your group uses it.

🧭 Case Study — Trekker Experiences
Emily from Canada (March 2025):
“I paid 550,000 VND at Lào Cai station for a SIM. It worked at first but stopped after a week. My friend who had a GoVnSIM eSIM ($14.50 for 20 days) had more data and no issues. I learned it’s better to buy online before arriving.”
Marco from Italy (April 2025):
“I trekked Fansipan with a Viettel eSIM (15 days, 5GB/day). Coverage was strong in town and usable at the summit. Another hiker had MobiFone from a shop in Sapa — it was cheaper locally, but he often had no signal outside town.”
