I had good to excellent coverage until 11 / 09 / 2009. On that Monday (3 days ago) my coverage was dropped... message when trying to connect: No Network Coverage. I drove a couple of miles to Berea and had a signal. So I called the AT&T assistance number, downloaded new data, etc. They are looking into the problem... . I know of 3 other AT&T customers on US 21 toward Paint Lick that lost their Network Coverage (NO SIGNAL... NO BARS) on that same day. I think one of their towers may have a problem, or they updated their network data, or they changed the power rating, or something changed, and our area is not in their coverage area. It could not be a problem with 4 different brands of phones with the AT&T network happening all at the same time unless some programming code / firmware / software was modified or a tower disabled. Since this is my only phone, I need to use it everyday and cannot drive 2 or 3 miles to get a signal. If this problem they created is NOT resolved very soon, I am switching providers. I don't won't to that since I have been with Cingular / AT&T several years and have always had good service until now. Please AT&T resolve this issue quickly... .
