If you already have an eSIM or are planning to buy one for your trip, you may be wondering whether it will work once you arrive in China.
Short answer: an eSIM only works in China if your plan includes China as a supported destination and your phone supports eSIM technology. You also need to install the eSIM correctly and enable the appropriate mobile data settings after arrival.
A travel eSIM allows you to stay connected without buying a physical SIM card, making it a convenient option for business trips, vacations and multi-country travel.
