at&t 

phone company (cellular and land line) that screws people out of their money with mediocre service and shitty reception. Sure, they cover 97% of America, but that coverage is only if you have roaming enabled on your phone, and even then you only get one bar.

And then we got the telephone (bill) here, AT&T: American Thieves and Thugs, which is another way of saying more money for the Mafia! -Archie Bunker, All in The Family, S7E18

Adjective.

Description of the effects of not-related-to-signal-strength mobile phone call quality problems.

To the other party in a mobile phone conversation: "Hay, could you say that last bit again, you went all AT&T on me".

A wireless phone company (also landlines and internet) with pretty bomb commercials. Not sure if their service is any good.
