Best Data + VPN Setup for Germans in China (2026) — Why You Probably Don't Need the VPN
You searched for a VPN. You don't actually need one — the right travel eSIM routes your traffic outside the Great Firewall so Google, WhatsApp, Sparkasse, Deutsche Bank, ING and Klarna all work. Complete setup for German travellers: eSIM, Telekom/Vodafone/O2 Wi-Fi Calling, bank photoTAN/pushTAN 2FA, Alipay with a German card.

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, Sparkasse, Deutsche Bank and Klarna all work like they do in Berlin. Here’s the complete setup for Germans: eSIM, Telekom/Vodafone/O2 WLAN Call for your home number, bank photoTAN/pushTAN, 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 Germans |
|---|---|---|
| Google, Gmail, Google Maps | Yes | Same as at home. Apple Maps also works. |
| WhatsApp, Instagram, YouTube | Yes | All blocked on local Chinese SIMs — WhatsApp is the main win for Germans. |
| Sparkasse, Deutsche Bank, Commerzbank, ING, DKB | Yes | photoTAN / pushTAN / BestSign all work. |
| N26, Revolut, Klarna | Yes | All work over foreign-routed data. |
| iMessage, FaceTime | Yes | Attaches to your German number. |
| Alipay, WeChat Pay | Yes — with German card | Both accept German Visa/Mastercard in 2026. Girocard doesn't work. |
| SMS-TANs to German number | Yes — via WLAN Call | Telekom/Vodafone/O2/1&1 all support it. |
Your German carrier: what to actually do
Telekom Travel & Surf China: €5-7/day; data rides local partners so Google/WhatsApp still blocked. Vodafone ReisePaket: €5-7/day; same firewall issue. O2 Free: out-of-bundle rates in China, worst option.
The move: buy a China-compatible travel eSIM for data and enable WLAN Call (Wi-Fi Anruf)on your German carrier so SMS-TANs and calls reach your German number free over hotel Wi-Fi. Turn OFF cellular data on the German SIM so you don’t accidentally trigger a Travel & Surf pass.
Paying for things in China as a German
Girocard doesn’t work in China. Physical Visa/Mastercard works at hotels and premium restaurants and almost nowhere else. Practical setup: install Alipay + link your German Visa or Mastercard before you fly. Top up ¥200-500 as a starter float. Every taxi, 7-Eleven, jianbing stand and metro turnstile accepts Alipay QR. WeChat Pay covers the same use cases; 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. Free VPNs almost universally fail on Chinese networks.

- Install Alipay and link your German Visa before you fly. Top up ¥300 as a starter float.
- Ensure pushTAN / photoTAN / BestSign is set up in your bank app before you leave.
- Turn OFF cellular dataon your German SIM to avoid triggering a Travel & Surf / ReisePaket pass.
- Optional VPN:ExpressVPN or Astrill installed before you fly. Probably won’t need it.
FAQ
QDoes Telekom / Vodafone / O2 roaming work in China?
ATelekom's Travel & Surf and Vodafone's ReisePaket both sell daily China passes at €4.99-6.99/day. Data rides Chinese domestic partners so Google, WhatsApp and Instagram still get blocked by the Great Firewall. O2 charges out-of-bundle rates in China. A travel eSIM at €10-18 for a whole week bypasses both cost and firewall.
QWill my Sparkasse / Deutsche Bank / Commerzbank / ING app work in China?
AYes, on a China-compatible travel eSIM that routes outside the firewall (YonoSIM, Nomad, Airalo, Holafly). Sparkasse pushTAN and photoTAN, Deutsche Bank BestSign, Commerzbank PhotoTAN, ING Photo-TAN — all work over foreign-routed data. SMS TANs to your German number arrive via Wi-Fi Calling.
QHow do I keep receiving SMS-TANs on my German number?
AEnable Wi-Fi Calling (WLAN Call / Wi-Fi Anruf) on your German carrier before you fly. Settings → Phone → Wi-Fi Calling → On (Telekom, Vodafone, O2, 1&1, congstar all support it). Your German number stays reachable over hotel Wi-Fi — Anrufe, SMS-TANs, and 2FA all still work.
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 German Girocard, Visa or Mastercard in China?
AGirocard doesn't work in China at all. Visa and Mastercard physical cards work at hotels and premium restaurants and almost nowhere else. Alipay and WeChat Pay both accept German-issued Visa/Mastercard in 2026. Install Alipay + link your card before you fly, top up ¥200-500 as a starter float.
