Issues with imessage/facetime after iOS 18.1 update

I have the iphone 15 pro. After updating to iOS 18, I had network issues where my phone would have an SOS where my service bars would be and a "No SIM available" notification on my phone. I would have to enable/disable airplane mode to get service again or I would have to restart my phone a few times. The option to toggle cellular data is also missing from the cellular screen in settings when the service goes down. Today, I updated my phone to 18.1 assuming that they would have fixed this annoying network issue. However, after the update, my facetime/imessages don't work. The facetime toggle and imessage toggle are automatically disabled/turned off and when I try to toggle it back on for imessages, I get an "error with activation" message. When I try to toggle it back on for facetime, I get a continuous loop with the same message that I have to close the entire settings page to exit the loop. Anyone else notice this issue?

Same here. I restarted my phone, went into the settings and turned iMessage off and back on again and after a few minutes it righted itself. Now it’s fine. Also it may have had something to do with your internet connection. Or it could be your cell phone reception. I watched it while it was having issues and it went to one bar. As soon as it came back up iMessage came back. Very strange.

This problem with the inability to receive SMS messages persists. I am unable to receive two-factor security messages from my bank, from a social media site, even from AT&T itself as I was in the process of replacing this iPhone 15Pro with a 16Pro - and was unable to get a code in order to complete the purchase! I've read n another Reddit chat (by jeff11ftracer) that Apple has an open case to resolve this issues. The problem has to do with a ping between the carrier and your phone. Resetting the phone and network settings won't make a difference, nor a new SIM card, nor a reboot. Reportedly the problem is with Apple engineering. Does anyone know the status of this work to fix the inoperable ping problem? My iPhone 15Pro remains not useful to me for many important functions until this problem is fixed! This is getting to be highly frustrating. Do I really need to reward Apple by buying a 16Pro, which will cost me approaching $1,000, to fix the problem Apple created on my 15Pro with its software upgrade? Apple should send me a new phone!
