Network problems on iPhone 13 pro

Hello, I have been using apple products for a very long time, I really love your products!

The problem is that I can't call anyone today. The Internet is working, the device recognizes the SIM card and the carrier, but when I try to call someone, or someone tries to call me, my network disappears, as if the SIM card is not inserted. I tried to reboot the device, tried to re-configure the telecom operator, the operating system version is up-to-date on 03/15/2023. Watch the video to make it easier to understand, Please help me with this problem!

I hope for a speedy response.

Sincerely, an ardent Apple fan.
