My phone was returned back from having a screen replacement. All seemed to be working correctly. What I did not know until I went out of the house to go shopping was that the phone would not connect to my mobile network whilst out and about, all it would show was Emergency calls only or no network connection at all, the reason that I did not notice this problem whilst at home was down to the phone using Wi-Fi calling which was working fine.
I spent an afternoon with my service provider checking to see if it was a problem their end but it was not.
I then started some diagnosis of my own, for information I also have an identical S23 Ultra phone that is my partners phone to compare with, also have a backup Samsung Galaxy A71 phone and also 3 different pay monthly (no problems on the account side) Sim card networks Three, ID Mobile & Vodafone to compare against.
Using my partners S23 phone I put both Sim cards in it and straight away they both connected to their network with strong 4G & 5G signal and not showing Emergency calls, Wi-Fi & Wi-Fi calling was turned off to make sure, everything working correctly. I then transferred both Sim cards to my A71 phone and again everything working correctly. Finally, I transferred both Sim cards back to my S23 phone and could only get Emergency calling so it is definitely something wrong with the phone as this problem was not there before your company carried out a repair of the screen.
The testing of transferring the Sim cards all took place in the exact same location and within a couple of minutes of each other.

Exact same thing happening to me. I have a Samsung Galaxy S21 Ultra, paid about $300 for the screen repair only to be left with a phone I still can't use!!! I had been using it just fine the entire year prior to the repair.

Connection problem??? What did that mean exactly? Maybe it's something I can mention to the repair tech to check out.

The most common cause of a faulty SIM network after screen repair is a misplaced or loose SIM card. During the repair, the technician might have dislodged it. Try taking your SIM card out and putting it back in. Try restarting your phone after that to see if it resolves the problem.
