I live in an extended digital coverage area, and I got a new iPhone 5s last month. Before that, I didn't have great service, calls were patchy depending on what part of the house I was in, but I never had a problem sending/receiving texts. Well, now I can almost never send or receive texts, and I definitely can't make calls, even when it's showing that I have 2 or 3 bars of service. It's getting annoying, because I'm almost always home, and trying to start a home-based business, and not being able to use my phone is going to be a problem. What's weird about it is that it only seems to really have been this way since I got my new phone. If anyone has any suggestions or any ideas why this might be happening, I would greatly appreciate the input.
