The Wikipedia table is community-edited and flags itself as needing updates, so treat its dates as a guide and not as a live status. Rules change without notice, and a block can be lifted or added from one week to the next.
Which connection are you on?
An answer about one app depends on the path your traffic takes: local mobile data, a hotel’s Wi-Fi or a roaming eSIM are three different routes. Airalo’s help page says its China eSIM routes data through gateways outside mainland China and that this does not apply to hotel Wi-Fi. That is the provider’s statement about its own product, not an independent test.

Check eSIM compatibility, carrier unlock, coverage and when validity starts. Buy and install while you have reliable Wi-Fi. Prices in US dollars, from each provider’s China page on the date shown. They change often.
Mark files for offline use
In the Dropbox app you can make files available offline. Select tickets, itineraries and scans before you leave, then confirm they open in airplane mode.
Keep a copy outside the cloud
Save a PDF of key documents in the phone’s own storage and send yourself a copy by email. Do not store passport scans in a note you share.
Do this before you fly
- Update Dropbox and check that you can sign in.
- Confirm that account recovery works without your home SIM if you plan to swap it.
- Save bookings, addresses and key contacts offline.
- Read the routing notes of the data plan you actually buy.
