im just curious if anyone else has this? i still have connections active, 5G and Wifi, but i still get that No Service on lockscreen. I tried removing and re-installing SIM card, I also enabled Airplane mode. This is Chinese version on T-mobile in US. Im also new to Xiaomi phones, so if this is normal, I apologize in advance. Thanks

Mine had the same issue. What I did was I went to settings->Notifications & Control Center->Status Bar->Edit Carrier Name. In there I just put whatever I wanted.
Question for you. Can you use VoLTE?

I am also having the same issue, except it's leading me to have some missed calls. I am on the EU rom and tried the VoLTE fix, do yall have any suggestions. I am using mint mobile.
It also gives me couldn't activate find device, cant connect to the network from the Xiaomi SIM Activation service, however, I can still send calls and get data.

"No service" message on a lock screen I have it too. And I on stock Chinese 12.5 with lock bootloader. (U can easily hide that message in a settings....even on stock rom)

VoLTE you have to activate with #*codes..

and after that you will find a switch in settings menu (sim card selection i believe)

yea, my big issue is im missing calls sometimes, where the phone sends it straight to voicemail without trying to connect. when it comes to selecting for phone calls it is stuck on the blue option, not my sim.
