We have AT&T Wireless at work, and we are allowed to offer the same deal to "friends and family" - in other words, anybody! All they have to do is call the correct sales rep and name the employee who referred them.
We can sign up for either a local, regional or nationwide plan with from 60 up to 1000 minutes. There are plans with 15% bonus minutes, free nights and weekends for a year, blah, blah, blah. I can't remember them all. Some have a free phone, most you have to pay something for the phone. Usually there are phone rebates to minimize the cost. If you are really interested in specific offers, PM me on Monday when I can look them up at work.
