Q: iPhone 7 Plus Stops Recognizing SIM Card
Not too long after I got the iPhone 7 Plus, I started having issues with my SIM card. Almost every day when I unlock my phone and it says "No SIM Card". I've got one in the phone. It just randomly stops recognizing it. If it helps, I'm using T-Mobile. I've cleaned off the card, made sure the phone was clean, but it keeps doing it.
iPhone 7 Plus, iOS 10.0.2, null
