Phone and apps
Direct answer
Most short trips can work without a Chinese phone number if mobile data, wallet setup, hotel contact, ticketing, and support paths are ready. The risk is that some local apps, Wi-Fi portals, or bookings may still ask for local SMS.
Editorial check
This answer stays short so a traveler can act quickly, then points back to the fuller guide and the official checks that may change before departure.
Current app account rules, foreign-number SMS behavior, hotel contact path, ticket platform requirements, Wi-Fi login rules, and the traveler's own roaming or eSIM setup.
Action path
A practical answer should leave the traveler with a few moves they can actually make before the trip or at the point of friction.
Use the foreign number for wallet and booking setup only after confirming SMS codes arrive.
Save hotel and support contacts in a format that works even if local app accounts fail.
Avoid plans that depend on one untested mini-program, Wi-Fi login, or same-day ticket flow.
Current checks
Recheck when app account rules, foreign-number support, or ticketing flows change.

Read enough to make the decision smaller, then open the checklist, search a specific question, choose a setup tool, or share the page with the person planning with you.
Use the checklist when the question has shifted from research to preparation.
Search by the actual problem: Alipay, eSIM, transit visa, first transfer, vegetarian food, or a city name.
Open recommendations when the task is clear enough for a short list to be useful.
