Why Vietnam is different
"The Ha Giang loop in northern Vietnam has Viettel-only coverage for 80% of its 350 km. Generic Vietnam eSIMs routed through Mobifone leave you offline for days on the most-photographed motorcycle route in Asia."
Vietnam received 18 million international visitors in 2024 and is growing faster than any other Southeast Asian country. Viettel, Vinaphone, and Mobifone split the market roughly evenly, but only Viettel has serious rural and mountain coverage in the north.
Our Vietnam plans use Viettel as primary. For the Ha Giang loop, Sapa trekking, and the Ho Chi Minh Trail, Viettel is the only practical choice.
Coverage you can actually measure.
We run Vietnam on 2 carriers so your profile falls back automatically if one signal drops. Coverage figures are measured against our own uptime data, not carrier marketing claims.

Troubleshooting
- Ha Giang mountain passes are Viettel-only. Do not rely on backup carriers here.
- Ho Chi Minh City metro (opened 2024) has cellular coverage in stations.
- Sapa treks into Muong Hoa valley drop signal — bring offline maps.

Questions people actually ask.
- Vietnamese tourist SIMs are cheap (~$3 for 30 days) but require passport registration at authorized shops, take 20+ minutes, and lock you into a single carrier. An eSIM skips all of it.
