Many familiar apps and websites are blocked on ordinary Chinese networks, so plan connectivity before you fly:
- Travel eSIM (easiest): install an eSIM from a provider such as Airalo or Holafly before departure. These data plans usually route traffic so that Google, WhatsApp, Instagram and Gmail work without any extra setup. Ideal for short trips.
- Local physical SIM: buy a China Unicom / Mobile / Telecom SIM at the airport (passport required). It gives you a +86 number and data, but to reach blocked apps you would still need a VPN.
- VPN: if you bring your own, install and test it before arriving. Public Wi-Fi alone will not reach blocked services.
Many travelers use both — a travel eSIM for data to Western apps, while keeping their home SIM active for bank verification codes.
