Does anyone of you have any idea about AT&T customer service number? I have been facing some serious network problems with my AT&T network. And above that all I don’t even have the customer care number where I can have a solution to my problem. I asked to some of my friends about the service center number but they said that it has been changed and they have no idea about the new customer care number. I am really in a big mess, so it will be of great help if you can provide me with the new AT&T customer care number?
