I already have a prepaid account but was going to add my wife and son using the multi-line feature, my question is do I have to buy phones specifically for prepaid or can I use use extra att phones I have or can I buy any att phone to use and how would I go about getting the phones activated and put on my multi-line prepaid account if I can use att phones that are not sold as att prepaid phones.
You can use any ATT compatible phone with prepaid. You need to set up a prepaid account for each line the same way you did for your line. Once they have accounts, then you can add them to your multiline plan.
