information request about at&t $2 unlimited talk and text plan.
I would like the full plan details for this plan. How is billing handled? Is a credit card kept on file and then just billed on a per-use basis? or is it a prepay of some sort, where you have a credit balance that the daily $2 is deducted from on the days the phone is used? Does the credit balance expire if it is not used within a specified number of days? How does paying for this plan work?
