In mainland China, access to overseas social and messaging services such as LINE, WhatsApp, Facebook, Instagram and YouTube is restricted on ordinary local networks and hotel Wi-Fi. Additional connectivity such as a VPN may be needed for restricted services, but VPN use is regulated and neither connection nor app availability is guaranteed. Before departure, ask your provider about communication options compliant with local rules and support for the apps you need.
Ask your provider about mainland coverage, data, calls and verification texts. Save maps, hotel addresses, tickets and emergency contacts offline; mountains can have no signal.
China uses UTC+8, one hour behind Japan. Check transport times in local time. Domestic supply is normally 220V, 50Hz: check device ratings and plug shapes and bring an appropriate adapter.
Arrange an alternative such as ordinary calls or SMS for contacting family and our team, and keep contact details and essential documents available offline.
