I've been with AT&T for about 6 years now and have tolerated subpar service and numerous dropped calls in my house. The only reason I have stuck with them is because they are the only carrier with service where I work. I was planning on switching to verizon for the new droid x, but after explaining my frustrations to AT&T retentions dept they offered me a free microcell to try out. I had to buy it from a local store, but they credited my account for the price. So far i am very impressed with it. My wife owns her own business that she runs from home, and uses around 3500 minutes per month, so the next couple weeks she will give it a very good workout, and I will update on here to let y'all know how it's going since there seems to be a lot of people complaining about the mcells.
