AT&T Mobility does not charge for paying by phone. I don't think you have to pay at AT&T stores if you pay by check and have your stub and drop it in the slot or box provided for payments. That's how I did it until the AT&T store moved two miles away. Then I tried paying by phone and it was easy. On the other hand, using their web site is one of the most complicated I have tried to use. Wes Leatherock snipped-for-privacy@aol.com snipped-for-privacy@yahoo.com
