Why can't I access my banking app on Chinese Wi-Fi?
Last updated:
Quick Answer
Symptom: Your home-bank or fintech app refuses to log in or warns "unsecured network" the moment you join hotel or café Wi-Fi.
Cause: Many Western banking apps block connections from Chinese IP ranges as a fraud-defense measure, and captive-portal Wi-Fi injects traffic that trips their security heuristics.
Solution: Tunnel through your VPN to your home country before opening the banking app, or switch to mobile roaming data which your bank recognizes as legitimate.
