An AT&T prepaid wireless customer can take advantage of a promotion, as of January 2016, that credits an existing card balance with 25 percent more minutes for free. Additionally, signing up for the promotional email mailing list ensures customers stay informed about other company promotions offering free minutes.
The AT&T PrePaid Minutes promotion offers customers the option of either receiving 25 percent more minutes added to an existing balance or donating the minutes to one of three charities. A customer must provide a PIN or card number along with the access number to begin the process of obtaining the free minutes.
To stay informed of future promotions for free minutes, customers must sign up for the promotional email list from AT&T’s PrePaid GoPhone page.
