You typed “VPN for China” into Google. You don’t actually need a VPN.The right travel eSIM routes your data through a network outside mainland China, so Google, WhatsApp, Instagram, Monzo, Barclays and HSBC all work like they do in London. Here’s the complete setup for Britons: eSIM, EE/Vodafone/O2/Three Wi-Fi Calling for your home number, bank 2FA, Alipay for taxis, and the belt-and-suspenders VPN.
The one-line explanation
Chinese ISPs (China Mobile, China Unicom, China Telecom) run the Great Firewall — any traffic that originates on a Chinese domestic network gets filtered. A travel eSIM from an international provider ( how the routing works) sits on the same physical towers but your data exits the country via Hong Kong or Singapore — so your phone browses from outside the firewall. No VPN app needed.
What works on a China-compatible eSIM
| App / service | Works? | Notes for Britons |
|---|---|---|
| Google, Gmail, YouTube | Yes | Same as at home. Apple Maps also works. |
| WhatsApp, Instagram, Facebook | Yes | All blocked on local Chinese SIMs. |
| Monzo, Revolut, Starling | Yes | In-app freeze/unfreeze card controls a real advantage in China. |
| Barclays, HSBC, Lloyds, NatWest, Santander apps | Yes | Bank fraud systems see foreign-network traffic as normal. |
| iMessage, FaceTime | Yes | Attaches to your UK number. |
| Alipay, WeChat Pay | Yes — with UK card | Both accept UK Visa/Mastercard in 2026. |
| Bank SMS 2FA to UK number | Yes — via Wi-Fi Calling | EE/Vodafone/O2/Three all support it. |
Your UK carrier: what to actually do
EE Roam Further: £6/day in China; data rides local partners so Google/WhatsApp still get blocked. Vodafone Global Roaming Plus: £7-8/day; same firewall issue. Three:Go Roam does NOT include China — you’re on out-of-bundle rates. O2: Travel Bolt On at £6/day.
The move: buy a China-compatible travel eSIM for data and enable Wi-Fi Callingon your UK carrier so SMS and calls to your UK number reach you free over hotel Wi-Fi. Turn OFF cellular data on the UK SIM so you don’t accidentally trigger a daily bolt-on.
Paying for things in China as a Briton
Physical cards work at hotels and premium restaurants and almost nowhere else. Practical setup: install Alipay + link your UK Visa/Mastercard before you fly. Top up ¥200-500 as a starter float. Every taxi, Family Mart, jianbing stand and metro turnstile accepts Alipay QR. WeChat Pay covers the same use cases if you prefer it; you don’t need both.
If you want a VPN as backup
Install ExpressVPN or Astrill before you fly— both maintain servers optimised for GFW bypass. Their websites and the App Store are blocked inside mainland China so you can’t download inside the country. Free VPNs almost universally fail on Chinese networks.
The complete British-in-China checklist
- Buy a China-compatible travel eSIM — installs from the QR at home on Wi-Fi. YonoSIM China plans →
- Enable Wi-Fi Calling on EE/Vodafone/O2/Three so 2FA codes and family calls reach you at hotel Wi-Fi.
- Install Alipay and link your UK Visa before you fly. Top up ¥300 as a starter float.
- Enable authenticator-app 2FA in your bank app — belt and suspenders on top of SMS.
- Turn OFF cellular data on your UK SIM to avoid triggering a Roam Further / bolt-on charge.
- Optional VPN:ExpressVPN or Astrill installed before you fly. Probably won’t need it.
FAQ
QDoes EE / Vodafone / O2 / Three roaming work in China?
AEE and Vodafone sell a Roam Further / Global Roaming Plus daily bolt-on for China at £6-8/day. Data rides Chinese domestic partners, so Google/WhatsApp/Instagram still get blocked by the Great Firewall. Three's Go Roam doesn't include China at all. A travel eSIM at £8-15 for a whole week bypasses both cost and firewall.
QWill my Monzo / Revolut / Barclays / HSBC / Lloyds app work in China?
AYes, on a China-compatible travel eSIM that routes outside the Great Firewall (YonoSIM, Nomad, Airalo, Holafly). Monzo and Revolut are especially useful because their in-app card controls let you freeze/unfreeze if a merchant looks off. Backup: enable authenticator-app 2FA (Barclays and HSBC both support it) before you leave so you're not dependent on SMS to your UK number.
QHow do I keep receiving SMS 2FA codes on my UK number?
AEnable Wi-Fi Calling on your UK carrier before you fly. Settings → Phone → Wi-Fi Calling → On (EE, Vodafone, O2, Three, Sky Mobile, Tesco Mobile all support it). Your UK number stays fully active over hotel Wi-Fi — calls in, SMS in, one-time bank codes in.
QDo I still need a VPN as backup?
AWith a Great-Firewall-bypassing eSIM, no. If you want belt-and-suspenders, install ExpressVPN or Astrill on your phone BEFORE you fly — the App Store and VPN sites are blocked inside mainland China. Free VPNs almost universally fail on Chinese networks.
QCan I use my UK Visa or Mastercard in China?
APhysical cards work at hotels and premium restaurants and almost nowhere else. Alipay and WeChat Pay both accept UK Visa/Mastercard directly in 2026. Practical setup: install Alipay + link your UK card before you fly, top up ¥200-500 as a starter float. Every taxi, Family Mart and street stand accepts Alipay QR.
