One decision before you buy
Two kinds of 'China eSIM' exist. Mainland-router plans are cheap and fast but sit behind the domestic internet (no Google, no WhatsApp, no Instagram). Roaming-router plans route through Hong Kong or Singapore and give you the open internet everywhere — including the trailhead where you need exactly one maps fix. For a walking trip, the roaming-router type is worth the premium.
The offline stack that never fails
Download before you fly: an offline China map set (Amap or Organic Maps), your GPX tracks in the navigation app of your choice, and the bilingual driver flashcards from our journeys as screenshots. In deep canyons even roaming eSIMs lose signal — the GPX + offline map pair is your real navigation.
eSIM, physical SIM, or both
eSIM activates on landing — ideal if your phone supports it. A physical China Unicom tourist SIM remains the budget fallback for longer stays. Many walkers run both: a data eSIM for maps and messaging, and the hotel Wi-Fi for everything heavy.
Quick Answers
Do I need a Chinese phone number for Alipay or 12306?+
No. Both accept foreign numbers at registration, and eSIM data-only plans work fine for them.
Will Google Maps work in China?+
Only through the roaming-router eSIMs or a VPN on mainland-router plans; on plain domestic data it will not resolve. Offline Amap is the reliable local layer.
How much data does a two-week walking trip need?+
10–20 GB covers maps, messaging, audio streaming on trains, and the occasional video call. Hotels and HSR trains have Wi-Fi for the heavy stuff.
Is my eSIM blocked in remote canyons?+
Signal follows settlements and ridgelines: the Gobi beacons and deep gorges have dead zones regardless of plan. That is precisely why every journey here ships a downloadable GPX.
