Unable to Activate iphone 7
Hello.
My iPhone 7 cellular stopped working a few days ago and message said I needed to update to continue using data. It wouldn't let me update through my phone but was able to through iTunes. It worked...for day. Today I lost my data again. Phone system says I have the latest update. So I tried to see if it was the sim card. When I removed it from the phone it didn't recognize that it was out. Same when I put it back in. So I did a factory reset and now the screen says Unable to Activate. Just wondering if there is any advice or info on what it could be or what to do next.
Thanks.
Dan
