I have an iPhone SE 2020 only 6 months old. Updated to OS 14.1 a while ago, then suddenly out of nowhere I couldn't send texts. Thinking it may be an OS bug, I updated to 14.2..... big mistake. I went from just no texting, to "No Service" at all. No calls, texts. I tried: reset network settings multiple times removed and replaced SIM card multiple times toggling airplane mode off, waiting 30 seconds, then back on several times toggling cellular data off, waiting a minute, then back on And I spent an hour with my service carrier, going through every single troubleshooting step they had. The said service on their end looks great, no problems. And they said they've had a ton of other people with the exact same problem asking for help today, but it's an Apple OS problem. So my phone is useless until Apple fixes this. No calls, no texts. Please developers, please fix this.
