EDIT: This offer has since expired, however this thread is the most current free AT&T minutes secret promotion. Best of luck!
If you've watched 10 minutes of broadcast television lately then you know the iPhone is now on Verizon's network. It used to be only available for AT&T users so you had bajillions of people using their network despite hating the company's horrendous service. Well now as a “thank you” to people not jumping ship over to Verizon,
AT&T users can text yes to 11113020 and have their account credited with 1,000 free bonus rollover minutes.
Yep, today's pretty slow…
I called AT&T twice to verify this. The first rep said this is only for iPhone users while the second said it only supposed to be for iPhone users but will work for anyone, so YMMV.
