Prepare mobile data, account access and essential transport tools before departure.

Arrange an international roaming plan, eSIM or local mobile service that matches the length of the trip. Keep access to the email and phone number used for payment and transport accounts, because verification messages may be needed.

Download offline copies of booking confirmations, hotel names in Chinese and essential contact details. The government’s 2025 guide recommends consulting telecom operators for a suitable data plan and includes foreign-friendly guidance for payment and transport apps.
