After 4 years if frustrating dropped calls in a marginal ATT coverage area I am finally complete. I installed the ATT 3g micro cell today and man what a difference. Full bars all over the house and parts of outside. No dropped calls. People think I am on a land line. Actually I am, the way this works is your call is transfered through the internet to an ATT land line. Crystal clear even while using my bluetooth headset. I know what your thinking, why pay $150.00 to get good service you are already paying for. I work from home, everybody uses my cell phone, my living is made on good cell phone service. This thing really works. Before and after pictures are attached.
