3 Ideas about How AT&T Could Evolve to Meet the Changes

I must say AT&T has such a "general" market. It has no specific segmentation for a certain group of people. My suggestion to AT&T is line extension by "adding individual offerings that appeal to different market segments while remaining closely related to the existing product line". For example, they could build lines for students and businessmen exclusively with different levels in price and services. 

Moreover, among all those carriers that apply 4G mobile broadband, AT&T is not that competitive in 4G technology, speed, coverage, plans and devices. With Verizon having the fastest 4G speed and T-mobile having the largest 4G network, the price and service that AT&T provide are not that attractive to users. AT&T is facing a fierce battle in the future 4G market. (4G Comparison [Infographic] | 2011 Review)

AT&T was rated the worst wireless provider both in 2010 and 2011 by Consumer Reports. A recent presentation by Gregg Heard, who is the VP-brand identity and design for AT&T, told us that AT&T's new strategy is to win consumer love. They would evolve their original "Rethink possible" slogan to focusing on human experience.
