View the following article and try to update to the latest iOS 18.2.1.

If your iPhone or iPad won't update - Apple Support

You may also need to visit your nearest Apple Store Genius Bar or an Apple Authorized Service Provider for diagnostics and evaluation.

Genius Bar Reservation and Apple Support Options - Apple

Then contact your carrier regarding your SIM issues.

i think its not carrier issue. I tried all the sim to other iphone and they are working fine. Regarding on the update. I flashed the ios 18.2.1 via itunes in dfu mode to prevent error 4000 when updating iphone not in dfu state via iTunes

I think your SIM is most definitely your carrier issue, and the update is your iPhone issue. Have you tried my advice above?
