I've had an iPhone 6 for about 4 months. It has worked perfectly up until last week. About that time, my phone lost service and "searching" was in the top left corner. It has been like that pretty consistently over the last week. I reset the phone multiple times and nothing changed. I took it to my local Verizon store today and they put in a new SIM card. They were pretty confident that was the problem. However, after an hour my phone had still not connected and still no service. They told me, pretty much, that my next option was to get a new phone. I don't want that. I just payed a lot of money for this phone a few months ago. Any suggestions?
