First safe move
Start here: Make mobile data work before the first airport-to-hotel transfer.
Back to readiness and recovery answers
Phone and apps
What mobile data setup should tourists use in China?
In short
Choose the data path that works before the first transfer: eSIM if the phone and provider support it, roaming if it is simpler, or a physical SIM backup if eSIM is not reliable for the device.

Editorial check
Reviewed as a concise travel answer
Phone, eSIM, maps, and app answers were reviewed with the current connectivity comparison and setup guidance.
- Information checked
Device eSIM support, carrier lock status, provider coverage, activation timing, roaming charges, and mainland China device limitations. Provider plans, device compatibility, app availability, roaming behavior, and network routing can change before departure.
Recovery template
Use the answer as a recovery path, not just a reading page
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.
Use app setup checklistFallback 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
Device eSIM support, carrier lock status, provider coverage, activation timing, roaming charges, and mainland China device limitations.
Action path
What to do next
A practical answer should leave the traveler with a few moves they can actually make before the trip or at the point of friction.
1
Make mobile data work before the first airport-to-hotel transfer.
2
Save hotel, route, and support details offline.
3
Treat map, message, and translation apps as dependencies, not decorations.
Official source
What an official source actually states
These facts are read straight from the operator's own page, so you can check each one at the source rather than take it on our word.
The local-SIM route is legally open to you on a passport
Article 7(4) enumerates a foreign citizen's passport as a valid ID for individual registration, so buying a mainland SIM is a real option rather than a grey area. The decision between that and roaming or an eSIM is therefore about coverage and cost, not about whether you are allowed.
Where in the source: 第七条(四): a foreign citizen's passport is an enumerated valid ID for individual real-name SIM registration.
Whichever route you pick, the ID check is not skippable
Article 6 obliges the carrier to collect a valid ID and true identity information, and Article 10 forbids it from activating the SIM if you refuse. Anyone offering a pre-registered mainland SIM without an ID check is offering something the carrier is not permitted to sell that way.
Where in the source: 第六条 and 第十条: valid ID required at sign-up; carrier may not process the SIM if refused.
Source: Ministry of Industry and Information Technology (工业和信息化部), 电话用户真实身份信息登记规定 (工信部令第25号), full text on www.gov.cn — 电话用户真实身份信息登记规定 (Provisions on Real-Name Registration of Telephone Users), 工信部令第25号 (source 工信部令第25号; read July 24, 2026)
What this source does not settle: The registration rule, and only that. It settles who may buy and what the carrier must do; it says nothing about data allowances, speeds, coverage outside cities, tethering, VPN behaviour, or prices — none of which any regulator publishes. Those belong to the carriers and to this site's connectivity pages, which mark them as operator claims rather than rules.
