Both of my kids have iPhone 7’s. Starting yesterday, after the 12.2 update downloaded (I assume) both of their phones have essentially stopped working. They cannot send or receive text messages. Calls immediately roll to voicemail. The connectivity indicator shows they are connected to 3G only (my iPhone X a couple feet away is on 5G). No internet, nothing. I am with one of the kids on a trip out of town (when all this started) and I reset her network settings and no change. Help! It’s especially stressful because we are out of town, so we have no way to communicate if separated.
