Internet in China: roaming, eSIM, local SIM and VPN explained
China has tightly regulated internet access, which calls for different preparation than most other destinations. Here's what you need to know before you leave.
Roaming with your own plan
Roaming with a non-Chinese plan is usually expensive and doesn't solve the blocked-services problem, an eSIM from an international provider is often the better choice.
eSIM for China
Some international eSIM providers route traffic via foreign networks, so many blocked services like Google or WhatsApp can work without a separate VPN. Check with the provider first, as this varies by eSIM.
Local SIM card
A local Chinese SIM doesn't give access to blocked services. If you use a local SIM anyway, you'll need a separate VPN to reach international apps.
The Great Firewall
The Great Firewall is the internet filtering system the Chinese government uses to control which websites and services are accessible within the country. Familiar services like Google, WhatsApp and Instagram are blocked as standard.
Do you need a VPN?
If you use a local SIM, you'll need a separate VPN to reach international apps. For Chinese services like Alipay and WeChat Pay you don't need a VPN, those work on any network, they're built to function within the Chinese internet.
Practical tips
- Always install your eSIM or VPN before you leave, downloading on arrival is often not possible since app stores and VPN websites can be blocked too
- Keep a second VPN as backup, some services get temporarily blocked and reliability can vary
- Download offline maps, translation packs and important travel documents in advance, Google Maps and Google Translate have limited use
- Check that your device supports eSIM before you leave
Our recommendation
For most travelers, an international eSIM that bypasses blocked services is the simplest solution for China, no separate VPN needed. Check our eSIM comparison for China for current options, or read more about VPNs for China if you're traveling with a local SIM instead.
