The difference between a smooth landing and a rough one is about twenty minutes of setup, done at home, where the Wi-Fi works.
China’s tourist infrastructure is app-shaped. Every gate, queue and menu runs through software, and the travellers who struggle are the ones configuring it on airport Wi-Fi. The whole stack installs in one sitting at home — this page is that sitting, in order.
The order
A roaming-style eSIM routes outside the mainland, which is why Google, WhatsApp and Instagram normally work on mobile data without a VPN. Install it on home Wi-Fi, test that it loads, leave the line switched off until you land. The honest comparison — Trip.com vs Airalo vs the Alipay shop vs a local SIM — lives in the four-way comparison; the short version is that Trip.com’s mainland listing is the simplest default for a single-country trip.
Register Alipay and WeChat Pay with your home number, verify with your passport, link a card to each — and remember verification is a review that can take a day or two, which is exactly why it happens at home. Fees: free at or below RMB 200 a payment, 3% on the full amount above (the limits page has the numbers). If an identity check stalls, the fix guide covers it.
One card in a second pocket and a few hundred yuan in cash. The apps work so reliably that the backup is boring — which is precisely why it should exist. And one hardware check before you fly: power banks must meet the flight rules, and phones shut down fast in a northern winter.
Yes. They have separate identity systems, limits and failure modes, and small merchants split between them. Setup takes minutes each, and having both means an account lock never strands you.
On a roaming-style eSIM, technically yes, but it is slow and poor on China detail. Amap is the navigation app locals use, has English UI, and works offline with downloaded city maps.
For trips under a month, the eSIM: installed at home, no queue, roaming routing for blocked apps. The airport SIM wins only when you need a real +86 number - the trade-offs are in our eSIM comparison and airport SIM guide.
It is almost always the face check - redo it under even light on Wi-Fi with all passport MRZ lines visible. The fix guide walks the whole sequence, including when to contact support.
