Internet in China: eSIM, roaming, local SIM — and keeping Google working
Updated 9 November 2026
Google, Gmail, WhatsApp, Instagram, Facebook, YouTube and many Western news sites are blocked in mainland China. How you connect decides whether they work for you.
The short answer
Your three options compared
| Travel eSIM | Home roaming | Chinese SIM | |
|---|---|---|---|
| Google, WhatsApp, Instagram | Usually work | Usually work | Blocked |
| Cost | Low–medium | Often high — check your plan | Lowest per GB |
| Setup | Install before you fly | Nothing to do | Buy in a store with your passport |
| Chinese phone number | No (data only, usually) | No | Yes — useful for some apps |
| Phone must support | eSIM | — | Unlocked phone |
Travel eSIM: how to set it up
- Check your phone supports eSIM and is carrier-unlocked.
- Buy a plan that says "China" or "China mainland" — not just Hong Kong. 1 GB a day is plenty for maps, payments and messaging.
- Install it at home over Wi-Fi by scanning the QR code, but leave it off.
- On landing, switch data to the eSIM and turn on data roaming for that line.
Hotel Wi-Fi and Chinese SIMs
On Chinese Wi-Fi or a Chinese SIM, you're on the domestic internet: Chinese apps (Alipay, WeChat, Amap, DiDi, Trip.com) work perfectly; blocked foreign services don't. Many visitors use an eSIM for their foreign apps and hotel Wi-Fi for everything else.
What about VPNs?
Unauthorised VPN services are restricted in China and many stop working without warning. If you rely on one, install and test it before you travel — you can't download it once you arrive. Roaming and travel eSIMs are the simpler choice for short trips.
Before-you-fly checklist
- eSIM installed or roaming plan confirmed for mainland China
- Offline maps and offline translation pack downloaded
- Important emails, tickets and bookings saved offline
- Alipay and WeChat set up while you still have home internet
FAQ
Does Google work in China?
Not on Chinese Wi-Fi or Chinese SIM cards. On international roaming or a travel eSIM, Google services usually work because your data is routed outside mainland China.
Does WhatsApp work in China?
WhatsApp is blocked on Chinese networks. It generally works on roaming or a travel eSIM. Most people in China use WeChat instead.
Can tourists buy a SIM card in China?
Yes, at China Mobile, China Unicom or China Telecom stores (including at major airports) with your passport. Blocked foreign apps will not work on it.
