For the benefit of anyone else who uses AT&T for a carrier and who may some day wish to make some changes to your account settings, let me just say that it's been a disaster.
The person helping me said she could make the necessary changes with no problem and started walking me through the necessary steps. At one point, she instructed me to go to 'Settings' and press a reset button. I told her I had been cautioned never to press that button because I'd lose passwords, notes, photos, etc. Anything of that nature that I had entered was at risk. She assured me that the only thing I'd lose were the photos I was using for my lock and home screens but that the ones in my album and my notes and contacts list wouldn't be lost.
She was partly right. I did lose my lock and home screens. I didn't lose my notes or contact list but I did lose my password from every website that I check into every day. I also lost the password for my wi-fi router and, omigosh, the password required for me to log into My AT&T. Can you believe this crap??
By the time I discovered all that I had lost, of course, we had long since ended our phone conversation so I could t tell her what I thought of her help.
The loss of my password for my router wouldn't have been so bad had I not misplaced the slip I had it written on. And, of course, with no router I also had no printer. And the router is the problem of U-verse, not ATT&T wireless. So I called U-verse support.
The support guy there assured me he could help me recover the router password and he'd guide me through it with me on my laptop. So he takes me to a webpage with instructions on it about how to recover or change my password. There are six or seven instructions, some with a few paragraphs, so without my printer I start writing down all these instructions because there are too many to remember. Fast forward to, say, instruction number four where it says if I scroll to here and click a button there my password should appear. Except that when I get to the page they're talking about, it's been changed and doesn't say anything about my lost password.
Gee, this is fun. I asked the support guy if there was any chance of him getting my hands placed around the throat of the person who told me to press that reset button. I didnt think so..... :-(
