Your phone will work if it’s unlocked, but local carriers block many foreign apps, and your home data plan likely won’t work. Getting a local SIM card or eSIM gives you affordable data and calling, which is essential for navigation and bookings.
Example:
A British traveler can buy a China Mobile or China Unicom SIM at the airport for ~$10–20 USD with 10–30GB of data. Alternatively, Airalo or Nomad eSIMs can be purchased before arrival for instant data access.
