I have a s23 ultra and been having network connection issues. I had a mint Sim and changed it to AT&T but still hardly get any signals on both the networks. I've tried everything and the only option left is to get another phone.
Although I bought my phone from UAE, it's been working for more than a year and the issue just started last month.
The biggest problem with using international models in the US is cellular band compatibility. If the network connectivity problem only started recently, it may be due to a hardware (i.e., antenna) issue. Have you performed a diagnostic? You can do it right on your phone under Device Care, or via the Support tab of the Members app (tap the "get started" button).
