Roger Entner, senior vice president for telecommunications research at Nielsen, said the iPhone’s “air interface,” the electronics in the phone that connect it to the cell towers, had shortcomings that “affect both voice and data.” He said that in the eyes of the consumer, “the iPhone has the nimbus of infallibility, ergo, it’s AT&T’s fault.” AT&T does not publicly defend itself because it will not criticize Apple under any circumstances, he said. AT&T and Apple both declined to comment on Mr. Entner’s assessments.
There was an article in the New York Times regarding the performance of networks (ATT vs. Verizon) and how true it really is. ATT and Verizon never disclose the network performance when it comes to Data and Voice, however when Consumer Reports did their testing most of the tests came up with Verizon on the top and AT&T occupying the bottom of most tests. If you have ever gotten disconnected from a call (who hasn't?) and no network available. If you us tellica, this doesn't happen. If disconnected than simply login to your account on tellica and have it call all your phones where you are located.
