Why is my eSIM not working on the Xiaomi 15 Ultra?
Check four things in your SIM settings: the travel eSIM is turned on, it is chosen for mobile data, data roaming is on, and your phone is not locked to a carrier. Then restart it.

Activation needs an Internet connection: stay on Wi-Fi for a few minutes, then restart the phone. Many travel eSIMs only connect once you land, so “No service” before you leave is normal.
