Getting mobile data sorted on arrival in China is one of the most important things you can do for your trip. Without a working data connection, you can’t use DiDi (no taxis), can’t use Alipay or WeChat Pay (payment problems), can’t use maps (getting lost), and can’t use translation apps (language barrier). It takes about 15 minutes at the airport SIM counter and makes everything dramatically easier.

Option 1: China Local Tourist SIM (Recommended)
The China Unicom Tourist SIM is the most popular choice for independent foreign travelers and the one most consistently available at major international airports.
Where to buy:
- Beijing Capital/Daxing Airport — China Unicom counter in Arrivals, international terminal
- Shanghai Pudong/Hongqiao — Unicom and China Mobile counters in both terminals
- Guangzhou Baiyun — China Unicom in the arrivals hall
- Chengdu Tianfu/Shuangliu — Both major airports have counters
- Most provincial capitals have airport SIM counters
What you get (2026 pricing):
- ¥99 plan: 20GB data, 30 days, no calls
- ¥150 plan: 50GB data, 30 days, 100 minutes local calls
- ¥200 plan: 100GB data, 30 days, unlimited local calls
Important: You’ll need your passport to register the SIM. This is mandatory — Chinese regulations require SIM registration with identity documents. The process takes about 10 minutes.
Does it include a VPN? No. The SIM connects to Chinese mobile networks that are subject to the Great Firewall. Google, YouTube, Instagram, etc. are still blocked unless you have a VPN installed. Install your VPN before arriving in China.
Can you top up? Yes — at any China Unicom store or via the Unicom app. Unicom stores are in every city and can handle top-ups and plan changes. Show your passport for any changes.
China Mobile and China Telecom Tourist Options
China Mobile and China Telecom also offer tourist-focused SIMs, though China Unicom has the widest international reputation for tourist services. China Mobile’s “OneConnect” tourist card is available at major airports and offers similar packages at similar prices.
China Telecom tends to have good coverage in rural areas in some provinces; if you’re doing significant rural travel in western China, ask the counter staff which network has best coverage in your specific destinations.
Option 2: International Roaming
If your home provider offers international roaming and you want zero hassle, roaming is technically possible. However:
The problems with roaming:
- Cost: Most European and North American roaming packages are expensive in China — ¥150-400/day equivalent in roaming charges
- Speed: Roaming data is often throttled after a daily quota
- Some providers cut off roaming data in China due to network agreements
When roaming makes sense: If you’re visiting for 3-4 days and the SIM switching process feels like too much friction. For trips of a week or more, a local SIM saves significant money.
Exception: UK Three network and a few other carriers have roaming agreements that provide relatively affordable China data. Check your carrier’s specific China rates before deciding.
Option 3: Hong Kong SIM Cards
If you’re entering mainland China via Hong Kong, or transiting through Hong Kong, buying a Hong Kong SIM card is an excellent option.
Why it’s good:
- Hong Kong SIMs are not subject to mainland China registration requirements (no passport required for some providers)
- Many HK SIM plans include mainland China data roaming at good rates
- Hong Kong is outside the Great Firewall, so apps work without a VPN while in HK
Best HK SIM options for mainland China use:
- China Unicom Hong Kong: Specifically designed for this use case; mainland China data rates built in; buy at Hong Kong airport or 7-Eleven stores
- CITIC Telecom CPC: Good cross-border data packages
- 1CONNECT (from HK): Data-only SIM with competitive mainland China data
Plan pricing: HK$80-200 (≈¥75-190) for 30-day plans with 20-50GB including mainland China data.
Option 4: eSIM (2026 Update)
eSIM support for mainland China has expanded significantly in 2026. Several providers now offer China-compatible eSIM plans that can be purchased online and installed before you depart.
Working eSIM providers for China (2026):
- Airalo China eSIM: Available through the Airalo app; plans from ¥80 equivalent for 1GB to ¥200 for 20GB; 30-day validity
- Holafly China eSIM: Unlimited data plan ≈¥250/7 days; activated via QR code
- GigSky: Available for iOS/Android; China plans from US$10 (≈¥70) for 1GB
eSIM pros:
- No physical SIM swap needed
- Can be installed before departure
- Can run alongside your home SIM (if your phone supports dual SIM/eSIM)
- Immediate activation
eSIM cons:
- Many Chinese eSIM plans have data caps (some “unlimited” plans are throttled after 1GB/day)
- Still subject to Great Firewall unless provider has work-around routing
- Slightly more expensive per GB than local SIMs
- Not all older phones support eSIM
eSIM vs physical SIM verdict: For travelers who don’t want to deal with a physical SIM swap, eSIM is a solid option in 2026. For budget-conscious travelers doing 2+ weeks, a local physical SIM from the airport is still better value.
The SIM/Alipay/WeChat Relationship
This confuses many visitors: your SIM card and your Alipay/WeChat Pay accounts are separate things. Getting a Chinese SIM doesn’t automatically give you a working Alipay.
What you need for Alipay:
- Download the Alipay app
- Register with your phone number (your foreign number or your Chinese SIM number)
- Add an international Visa or Mastercard
- Complete identity verification (passport photo + selfie)
The phone number on your SIM is used for receiving verification SMS codes when you log in or make transactions. Having a Chinese SIM number makes this smoother, but many foreign travelers successfully use Alipay with their home country phone number.
WeChat Pay works similarly — the WeChat account is tied to your phone number. A Chinese number means you’ll have fewer restrictions on your account.
Practical SIM Checklist
- Check your phone is unlocked for foreign SIMs (if you bought it on a carrier contract, it may be locked)
- Find out if your phone takes nano-SIM, micro-SIM, or is eSIM-only
- Install your VPN app before arriving in China
- Download Alipay and set up payment before or immediately on arrival
- Download DiDi (taxi), Amap (maps), and Baidu Translate while on your home network (or via VPN in China)
- Note your hotel address in Chinese characters — you’ll need this for DiDi
The 15 minutes it takes to get a SIM sorted at the airport is unambiguously worth it. Don’t skip it to save time — you’ll spend more time later struggling with payments and navigation.
