Cellular problem after updated to iOS16.1.1

Updated to IOS16.1.1 last night. After finishing updating, system shows there is a cellular problem. There is a triangle warning sign at the top right corner next to wifi sign.


I restated iPhone it didn’t work.

I reinserted SIM card it didn’t work.


Oh my screen background was gone and turned to black after I restarted the iPhone…


Currently it’s showing four dots like it’s searching for signals.


And in the settings it’s just showing “Error” under Cellular service.


How can I fix this???
