About AT&T

On October 26, 2004, AT&T Wireless completed a merger with Cingular, a joint venture of SBC Communications and Bell South. When the dust settled, only the Cingular brand name remained. Because the Cingular brand appealed to a younger demographic and AT&T appealed to an older one, there has been a confusing convergence ever since, with many people still unsure what exactly happened. The bottom line is that AT&T merged with Cingular, and in sheer number of customers (approx. 63 million) remains the largest of the wireless carriers in the United States.

While AT&T Wireless may be the largest carrier in total number of customers, a closer look at the metrics reveals that it lags behind rival Verizon in such key areas as customer cancellation rates and a less than stellar customer service ranking.

AT&T Wireless operates on the GSM platform, providing "world capable" phones right out of the box, something its rival Verizon cannot lay claim to matching. A typical AT&T phone will function without modification in over 190 countries. They offer a large selection of GSM devices from such manufacturers as LG, Samsung, RIM, Motorola and others.

Although AT&T remains the largest US carrier in large part through acquisitions, it is worth noting that Verizon Wireless has gained tremendous ground by building its base without such acquisitions. The battle between AT&T Wireless and Verizon Wireless plays out daily in a multi-billion dollar advertising and marketing campaign for all to enjoy.

Coverage and compatibility, at a price

from The Wirecutter (2 months ago)

If Verizon’s choice of phones or T-Mobile’s coverage bother you, go with AT&T. You’ll pay more, especially if you bring your own device, but you’ll have coverage that comes close to Verizon’s and customer service that put it atop J.D. Power’s surveys (although... More

Can't beat it!

(2 years ago)

We were with AT&T for about 10 yrs and were perfectly happy with no problems. Some family got a deal with Verizon and they got us to go with them. I could not wait for that 2 yr contract to be up. They were rude, arrogant and clueless to say the least. Every time I had a problem, they'd delete my ap... More


Not a good service at all

(3 years ago)

I have had AT&T for many years for my cell service, but I am looking for another company. I cannot talk for more then 10 minutes before I am dropped. My daughter switched her cell service to Metro and is so very happy. She called AT&T to be sure her contract was up. They told her both on the phone a... More

I've had AT&T for the past few years now with my phone, and I've had an overall decent experience.


Overall Good

(5 years ago)

The only annoying thing about Cingular is that it drops my calls semi-frequently, despite their commercial claims. It's not the area I live in either. I've done a lot of research and their family plan is the cheapest out of the top companies. We have been with the company for about 7 years now, a... More
