SIM cards and internet
Airport kiosks, eSIMs, and coverage on the mountain roads.
At the airport
Prepaid tourist SIMs are sold in the arrivals hall and are cheap for ten days of unlimited data.
Bring your passport; registration is mandatory.
On the mountain
Coverage is good in villages and patchy on farm roads. Download offline maps before you go up.
Most cafés have Wi-Fi, but the password is often on the wall in Chinese only.
