Hello! I woke up this morning to a message on my phone saying invalid SIM card. I tried updating my phone and it got the 4 bars on the top right corner back. But whenever I text someone it sends from my email. And I don’t have “lte” next to my wifi, making me believe I don’t have cellular data. I haven’t touched my settings at all and this all occurred last night when I was asleep. This is very frustrating considering I haven’t done anything different in my iPhone.
