AT&T may want to be the darling of the US wireless carriers, but some of its policies are seemingly designed to turn a customer into an enemy and not an ally. Such is the case with its 3G MicroCell which is promoted as being a solution for those with cellular coverage issues. For those unaware, the 3G Microcell is a hardware device that lets customers use their broadband Internet connection to make and receive phone calls and, in the case of AT&T’s 3G-enabled MicroCell, to utilize the 3G data capabilities of their phone. On the surface, this sounds like a win-win solution with customers receiving solid 3G cellular coverage and AT&T offering a solution for customers with coverage issues. Unfortunately, AT&T seems destined to shoot itself in its foot by instituting a data usage policy that counts data used through the MicroCell against your cellular data allotment. Seems a bit counter-intuitive that AT&T is charging for data used through the MicroCell when the bulk of the data transmission is carried by your broadband Internet provider, no?
