iPhone Xs Max, with eSIM on T-Mobile, and physical SIM on Verizon, iOS 13 Beta 4. Each time I reboot the device, or put in into Airplane Mode (once I exit Airplane Mode), I get a message telling me "Unknown Cellular Plan Ready to be installed" (posting screen shots of messages). If I click cancel, it just does nothing, if I hit "continue" I get "Cellular Plan Cannot Be Added". I've had eSIM with T-Mobile for several months now and physical SIM with Verizon as well, never seen this before, even with the previous builds of iOS 13. I had went back to 12.3.1 about a week ago, and then updated OTA to 13 Beta 4 and have gotten this message since. I didn't see where anyone else had posted this happening, but was wondering if it's need for concern. I can easily go back to 12.3.1 if needed, but then that'd leave my watch useless since it's also on the WatchOS beta. Calls/data works just fine, so no issues there either, just wondering why all of a sudden I am getting this annoying pop up, and any suggestions to fix. Thanks.
