Getting a working data connection in China doesn’t require visiting a Chinese mobile operator or figuring out registration requirements. eSIM technology and improved international roaming plans have made this dramatically easier — you can now set up reliable internet access before you even board your flight.

eSIM vs Physical SIM vs Roaming: Which Is Best?
| Option | Setup time | Cost | Data speed | Voice calls | Best for |
|---|---|---|---|---|---|
| eSIM (third-party) | 10 min (before travel) | USD 15–40/week | 4G LTE | Data-only (WhatsApp/VoIP) | Most travellers |
| Physical Chinese SIM | 30–60 min at airport | ¥50–¥150 | 4G/5G | Yes (local number) | Long stays (2+ weeks) |
| Your carrier’s roaming | None | USD 10–15/day | Usually 4G | Yes | Short, simple trips |
| Pocket WiFi device | 20 min at airport | ¥50–¥100/day | 4G | No | Multiple devices |
eSIM Options That Work in China
What makes a China eSIM different
Most eSIM providers don’t work well in China — the Firewall blocks many data routing paths. You need a provider specifically designed for China connectivity, using data routing that bypasses or passes through the Firewall on specific licensed channels.
Airalo China eSIMs
Airalo is the most accessible eSIM marketplace for China:
- China-specific eSIM plans using ChinaUnicom or ChinaTelecom infrastructure
- Prices: ~USD 15 for 1GB / 7 days; ~USD 45 for 5GB / 30 days
- Important: Airalo China eSIMs give you a mainland China data connection but do NOT include VPN bypass capabilities. You still need your own VPN.
- Setup: install Airalo app → purchase China plan → install eSIM profile (takes 5 minutes)
- Compatible devices: iPhone XS or later with unlocked eSIM slot; many Android phones (check your model)
Nomad China eSIM
Nomad (formerly HolaFly for some regions) offers similar plans through Chinese carrier infrastructure. Slightly different pricing — compare current rates on nomadinternet.com.
Ubigi and BNESIM
Other platforms offering China eSIMs. Generally similar performance — compare on data quantity per dollar rather than marketing claims.
GigSky
GigSky offers a “Rest of World” or Asia plan that includes China. Useful if you’re travelling through multiple countries and want a single eSIM.
How to Set Up an eSIM Before Your Trip
Check device compatibility first
Your device must be:
- eSIM-capable (most phones released after 2019 are)
- SIM-unlocked (not carrier-locked to a network)
- Running a recent OS (iOS 12.1+ or Android 10+)
Check on iPhone: Settings → Cellular → Add Data Plan (if this option exists, you have eSIM)
Check on Android: Settings → Network & Internet → SIM → Download SIM (varies by manufacturer)
Step-by-step setup with Airalo
- Download Airalo app (available outside China, download before arriving)
- Purchase a China data plan — choose GB quantity and duration that covers your trip
- Install the eSIM profile: Airalo sends a QR code; scan it in your phone’s Settings → Cellular → Add Data Plan
- Set to “Data Roaming Off” on your primary SIM to avoid accidental roaming charges
- Set the eSIM as your primary data SIM in cellular settings
Keep your home SIM active but on voice-only — this lets you receive 2FA verification SMS from your home bank.
International Roaming Plans from Major Carriers
If you’d prefer to use your existing mobile carrier:
Which carriers have China-compatible roaming
Not all international roaming plans actually work in China — some carriers route data through Google infrastructure, which gets blocked. Test your roaming before committing to it by making a note of whether your carrier’s roaming has worked in China for other customers.
Generally reliable roaming in China:
- T-Mobile (US): “T-Mobile International” includes China with 2G roaming free; pay for high-speed
- EE / Vodafone (UK): international roaming plans include China; data goes through UK routing
- Telstra (Australia): roaming plus plans generally work in China
- Singtel / StarHub (Singapore): reliable China roaming
Potentially problematic:
- Carriers that route all international data through US infrastructure may experience issues if that routing interacts with China’s Firewall
The honest cost comparison
At USD 10–15/day, a 2-week trip on carrier roaming costs USD 140–210. An Airalo eSIM for 30 days (5GB) costs USD 45. For data-heavy travellers, the eSIM wins on cost.
Pocket WiFi Devices
A portable WiFi hotspot (“pocket WiFi” or “MiFi”) rents from airport kiosks at major Chinese airports:
- Cost: ¥50–¥100/day
- Deposit: ¥200–¥500 (refunded on return)
- Speed: 4G LTE in cities, variable in rural areas
- Advantage: multiple devices share one connection — good for families or groups
- Disadvantage: one more device to charge and keep track of
Providers at airports: ChinaWifi, ChinaSIM, and similar kiosks are present at major arrivals halls. Look for counters near the arrival exit area.
Return: most kiosk operators allow return at the same or partner airports; some allow courier return.
Troubleshooting Connectivity Issues
eSIM not connecting after arrival
- Toggle Airplane Mode off/on to force network re-registration
- In Settings, confirm the eSIM is selected as the active data line
- Manually search for networks and select China Unicom or China Telecom
VPN not working through eSIM
The eSIM gives you a data connection, but VPN functionality still depends on your VPN app. If your VPN doesn’t work:
- Switch to “Stealth” mode
- Try a different VPN server
- See our VPN guide for detailed troubleshooting
Apps requiring a Chinese phone number for verification
Some Chinese apps (Didi International, WeChat) can register with international phone numbers. Others require a Chinese number. If you need a local number for registration purposes, a physical Chinese SIM is necessary.
Getting a Physical Chinese SIM Card
If you decide a physical SIM is better for your trip:
At the airport:
- China Mobile, China Unicom, and China Telecom all have counters at major international airports
- Tourist SIM packages: typically 30-day plans with 10–20GB for ¥100–¥150
- Requirements: passport; registration takes 10–20 minutes
At a carrier store:
- Available in every city; stores are in every shopping mall
- Staff speak basic English at airport branches; carrier stores may require translation
- Some packages require Chinese ID to register — tourist-specific packages exist that use passport registration
Important: Chinese SIM data is subject to the same Firewall restrictions as any Chinese internet connection. A Chinese SIM does not bypass the Firewall — you still need a VPN.
