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???

FroYoyo ~ Your iPhone is in Low Power Mode (indicated by the yellow battery icon at top right.) Apple advises to leave Low Power Mode off when you don't need it:

Use Low Power Mode to save battery life on your iPhone or iPad

...See if anything improves after you've turned off Low Power Mode:

Settings > Battery > Low Power Mode = Off.

FroYoyo ~ This is that page:

If you see a Cellular, Ultra Wideband, or Apple Pay Issue message after an iOS update or restart

...And so did you "try more steps on your own" listed there?

FroYoyo ~ What model of iPhone is it?...

Settings > General > About > Model Name

Does it still have its original battery?

And what's the Maximum Capacity % here?...

Settings > Battery > Battery Health

Removing and reinserting the SIM did not resolve the dropping of cellular service, after the upgrade to iOS 16.1.2. Resetting the network resolved the problem on my iPhone XS Max.
