Internet in China, VPNs and connectivity
The important points to settle before you set off. This is here to bring order to the planning; the official details are worth checking close to your departure date.
Not every Western internet service is available or fully functional in China. Some apps, news sites, Google services and certain communication features may be restricted. So work out in advance what you genuinely need during the trip: maps, WhatsApp, email, remote work, or steady access to Western services.
For connectivity there are several good options: an international eSIM, a local SIM, or a roaming package bought at home. In most cases an eSIM and a home roaming package route through infrastructure outside China, so by default they reach services blocked behind the GFW without needing a VPN. A local Chinese SIM, by contrast, runs through the local network — so if you need access to blocked Western services, you will usually need a VPN as well.
If you choose to rely on a local SIM, or need a backup for work and communication, install, configure and test a VPN before your flight. Arriving in China and only then starting to look for a solution is a bad idea, when convenient access to app stores, verification and the providers' own sites is already gone. Either way, check the data allowance, speed, tethering support, coverage in cities and remote areas, and whether you get comfortable access to the services you actually use.
In summary
- Install and test a VPN before the flight, if you need one.
- Decide in advance between an eSIM, a local SIM or a roaming package from home.
- Remember: an eSIM or a home package usually needs no VPN, but a local SIM may.
- Make sure the package supports tethering and has enough data for the whole trip.
- Keep activation instructions, QR codes and provider details somewhere available offline.
