AT&T owns:
AT&T Alascomm
AT&T Communications
AT&T Laboritories
AT&T Communications owns Comcast, and many, many of the baby-Bells; including SBC Communications. Too many to list. Go to wikipedia for a list.
But, they do NOT own T-Mobile (owned by Duetsch Telecomm) or Sprint (who did by Nextel.)
att
you either have to switch companies or talk to a business person that works for ATT
no. they do not
i know for sure that att has the iPhone and i believe that Verizon is about to begin selling them.
I would call ATT&T a monopoly ( they were broken up in the 1980 as Pacific Bell and became the "baby Bells" and then morphed into ATT&T. They have bought back many of the "baby Bells" and own wireless companies, Internet and TV services. If they aren't a monopoly today they are close to it. Time/Life could be one as well. They own TV networks, AOL, magazines, newspapers, movie studios, publishers.
The kind of telephone switch type at the ATT Phillips Tel 5ESS-PBX host is a step by step tone. This is the standard switch type used by ATT and most large telephone companies.
I would recommend that you first of all check with the major phone companies like ATT or Sprint. After that I would compare the prices they quoted and if they had a package that fit you. If that didn't work there are smaller lesser known companies that you could contact. One company that I could recommend is Comcast they have excellent customer service and you have the ability to make your own custom package that includes any features that you see fit. Another company that features the make your own package is ATT and they will be willing to work with you in whatever direction you would like to go.
Well, they are two different corporate companies. AOL is America Online and ATT is American Telephone and Telegraph company. AOL deals with online services and ATT is for wired/wireless communication.
cricket, sprint, att, verizon, wireless, and you find the fifth one.
you just make up your own code when you first get
I don't know if they own pharmaceutical companies but it should be a conflict of interest and a crime if they do.
Att is a Internet , Cable , and Home phone company. There is no 1 thing that att does
