Independent China travel · connection guide
Choose between home-carrier roaming, a travel eSIM and a mainland SIM based on the number you need, your device, trip length and tolerance for setup.
China now
Mobile connectivity is part of a wider app-and-identity system. Set up the layers you need before treating the phone as your only backup.
Roaming or a travel eSIM can get you online quickly, but many travel eSIMs are data-only. A +86 number can make SMS verification, driver or delivery calls and some local services easier, so decide whether you need both connectivity and a local number.
Apple travel-eSIM guidance ↗Expect real-name registration with the original passport at an operator service hall. Foreign-passport processing is not available at every small reseller, so a directly operated hall is the safer first stop.
National Immigration Administration ↗Taxis, transport codes, tickets and dining tools may run as mini programs inside Alipay or WeChat. Working data is only the first layer: account sign-in, identity checks, permissions and a supported payment method can still matter.
State Council visitor guide ↗For a short trip, home roaming or a pre-installed travel eSIM is usually the quickest start. Add a mainland SIM when a +86 number, ordinary calls/SMS or a longer local plan materially helps your trip. Keep your home line available for account verification, but block unintended data use.
Compare your options
There is no single best option. Prices and packages change by carrier, sales channel, trip length and promotion, so compare the actual plan terms rather than a headline price.
Keep your home line
Best for: Short trips, immediate connection and receiving messages on your usual number.
Set up: Arrange with your home carrier before departure.
Fast data setup
Best for: Unlocked eSIM-capable phones and travellers who mainly need data.
Set up: Buy from a worldwide provider and install before entering mainland China.
Get a local number
Best for: Longer stays or travellers who need a +86 number for calls, SMS and local services.
Set up: Apply in person at an operator service hall with your original passport.

Need a +86 number?
These are current Shanghai visitor benchmarks, not nationwide guaranteed prices. A mainland SIM does not by itself promise access to overseas apps.
Shanghai benchmark: CNY 90 · 30 GB · 100 voice minutes · 7 days
Local +86 number. Bring the original passport to a directly operated service hall. Hotspot, SMS allowance and the exact network tier were not stated in the current English visitor tariff.
Shanghai benchmark: CNY 58–80 · 10 GB · 100 voice minutes · 7 days
Local +86 number. The exact price within the published range is confirmed at purchase. Separate Beijing visitor products advertise 5G, but terms are product-specific.
Shanghai benchmark: CNY 85 · 20 GB · 100 voice minutes · 7 days
Local +86 number. Short-term 7-, 15- and 30-day products are reported in current Shanghai visitor guidance; availability varies by branch and city.
Important 2026 distinction
A travel eSIM is usually a roaming data profile sold by a worldwide provider. It can be used on a compatible unlocked phone and is often installed before travel.
A mainland carrier eSIMis a local line issued by a Chinese operator. Apple’s current mainland guidance says China Mobile, China Telecom and China Unicom support eSIM on iPhone 17e model A3635 and iPhone Air model A3518. Activation requires a carrier-store visit and ID check. Other iPhone models—including models bought outside mainland China—cannot install a mainland-carrier eSIM profile. Device support outside this Apple guidance is carrier-specific, so confirm directly before relying on it.
Before departure
Do the downloads, logins and account recovery at home. The arrival hall is the wrong place to discover a carrier lock or a missing password.
Ask the seller or home carrier. On iPhone, Settings → General → About should show “No SIM Restrictions” beside Carrier Lock.
Give the exact model number—not only the model name—to the chosen provider or mainland operator.
Confirm mainland China coverage, full-speed allowance, daily reset time, incoming SMS, calls, tethering and what happens after the allowance is used.
Save its QR code, APN instructions and support contact offline. Follow the provider’s activation timing so the validity period does not start too soon.
Know how to select a separate data line, disable cellular data switching and control roaming for each SIM.
Save hotel details in Chinese, booking screenshots, critical map pins and Chinese/English translation packs.
Do not discard the line that receives bank or email verification codes. Store recovery codes somewhere secure and accessible offline.

Common pitfalls
Most travel eSIMs are roaming data products. Check whether a phone number, ordinary SMS, voice calls and hotspot use are included.
Installation can require Wi-Fi, an app login or access to the original email. Install and save recovery details before departure whenever the provider permits.
Dual-SIM phones can move data to the home line when the travel line is weak. Set one explicit data line and review per-line roaming switches.
A reseller or small branch may not handle foreign documents. Use a directly operated service hall and take the original passport.
Ask whether the plan renews, how to top up and how to close it. NIA guidance says a number no longer used should be cancelled at an operator branch.
Some captive portals require SMS or identity verification, coverage can be patchy, and open Wi-Fi is unsuitable for sensitive account work.
Service availability and routing can differ by network and can change. Follow Chinese law and provider terms; this guide does not promise or advise a way around network restrictions.
Direct answers
For a short trip on an unlocked compatible phone, a travel eSIM is usually the simplest data option. Use home roaming if keeping your existing line matters more than price, and choose a mainland physical SIM when a +86 number, calls or SMS are important. The best product is the one whose live terms match your phone, dates, data use and required apps.
It depends on the product's routing. Some providers explicitly advertise access to examples such as Google, Gmail, Google Maps, WhatsApp, Instagram, Facebook, TikTok and other overseas services; others do not make an app-by-app promise. A mainland physical SIM follows mainland network conditions. Read the exact product page and never treat the word “eSIM” itself as a guarantee.
Not for every trip. Data can cover maps, translation and app messaging, while a +86 number can make driver calls, local SMS verification and some local services easier. Keep your home line available for bank or account codes even if another line supplies the data.
Install it before departure while you have reliable Wi-Fi and account access, but follow the provider's activation rule so the validity period does not begin early. Save the QR code, APN, support contact and manual-install details offline.
Confirm the correct data line is selected, follow the provider's Data Roaming instruction, disable automatic cellular-data switching, check the APN, remaining allowance and supported local network, then restart the phone. Contact the provider before deleting an installed eSIM, because some profiles cannot be downloaded again.
Sources & service links
Government, regulator, operator and device-manufacturer pages take priority. Your exact carrier plan and phone model still control what works.
