Phone and apps
In short
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
Phone, eSIM, maps, and app answers were reviewed with the current connectivity comparison and setup guidance.
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. Provider plans, device compatibility, app availability, roaming behavior, and network routing can change before departure.
Recovery template
Start with the immediate move, keep a human or offline fallback, and only rely on live rules after checking the official operator, provider, or source.

Start here: Use the foreign number for wallet and booking setup only after confirming SMS codes arrive.
Fallback path
Use saved offline hotel details, home-SIM SMS or roaming, hotel Wi-Fi, provider support, and screenshots until mobile data is stable again.
Do not assume
Do not treat this answer as final live proof. Do not use as proof of current network access, app availability, provider routing, or device compatibility without checking the live provider and device state.
Source boundary
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.
