AT&T’s Microcell is like having your own personal cell phone tower for your home. You plug it into your router, and it sends out 3G wireless service to your home. They normally cost $150, but one customer has gotten one for free, just for being a loyal customer.
This customer complained once to AT&T, in a civil manner, that the wireless service wasn’t reliable in his home. He and his family were on AT&T’s plan, for about $180 per month. His contract will be running out soon, and AT&T has sent him this free Microcell to improve his reception at home, most likely to keep him as a customer.
Still, you can’t argue with free hardware to fix your reception issues.
