iphone 14 no service

Hello everyone,

I have a problem with an iPhone 14 with no SIM restrictions but not able to connect to the carrier´s network.

I tried everything possible including changing SIM cards, eSIMs, another carrier, locations, countries, continents, I updated the phone, I did all the required resets including network settings, I erased the phone several times, I contacted Apple (Apple checked my phone and said it is fine) and I contacted different carriers with no success.

Please, if you would like to help, go ahed and write your comment but do not repeat what Apple keeps saying that the issue is with the carrier. This is an unlocked phone and I bought it brand new from an Apple reseller. It worked perfectly for seven months and stopped connecting to any carrier.

Thank you
