Phone signal and eSIMs on China's famous routes
TrailSim lists 1 route in China. None has a published coverage report yet — no public signal data source describes these corridors well enough — so each page sells the eSIM on the local networks and says so plainly.
China routes without a report yet
The eSIM, delivery and refund are the same; the page says plainly that no coverage report exists for the corridor.

Frequently asked questions
Which eSIM works best for hiking or driving in China?
It depends on the route: each of China's networks holds in different places, so TrailSim compares them along each route and features the plan whose networks cover the most of it at a sensible price. Every China route page lists current plans and, where a report exists, the dead zones with GPS coordinates.
Is there phone signal on hiking trails in China?
TrailSim has not yet modelled coverage on its China routes: no public signal data source describes these corridors well enough for an honest report, so the pages sell the eSIM without one and recommend offline maps for the remote stretches.
Do the plan days start when I buy?
No — on first use. Installing the TrailSim eSIM and connecting in China starts the clock, so you can buy weeks ahead. Uninstalled eSIMs can be refunded within 14 days.
