So I've had AT&T for about 10 years now and have always lived in the same house which I've never been able to get above 2 bars. I will sometimes maybe peak at 3 bars but very rare. So I finally decided to give AT&T a call and see what they could do. They said they would give me a MicroCell for free and it should greatly help with the service, so they credited my account for $200 and I went to AT&T the next day to pick it up. Just finished setting it up, very simple plug into the wall and plug the ethernet cable into the microcell and then into your current modem and your done! Wait about 20 mins and its activated. No monthly fee or anything. I now get full 5 bars around my entire house! No dropped calls or anything. Using it with my iPhone 5, it supports up to 4 devices at a time. So if you dont get great service I highly recommend it!
