The area your home or office is in

Depending on the area your home or office is in, AT&T might as well offer additional incentives in terms of service bundling with Internet service, cable TV, and wired/VoIP (Voice over Internet Protocol) phone service. Verizon has similar deals, now if it doesn't provide service in your area, there might be benefits to sticking with AT&T.

AT&T has some work to do. Whether real or perceived, its network has issues and AT&T needs to invest in both infrastructure and marketing to repair its reputation. Meanwhile, even though, make sure you weigh all of the factors--not just a Consumer Reports survey--previously defecting to a different wireless provider.
