Thanks Wild Banchi. I was planning on buying the phone from Amazon.
I used the AT&T web site to see what it would allow you to do. I looked at GO Phones and the Samsung Galaxy Express was on the list. When you go to select a plan (and select $.10 a minute) , and then select a phone to match the plan, the Galaxy disappears from the options list and you are left with the rest of the choices.
I looked on eBay for microSIM cutters. I assume that I need one that will fit AT&T. Most of the cutters I saw stated that they were for IPhones. I really hate to be such a pain )&**% but I hate having to pay for stuff (a data plan) when all I want is a decent phone. Just a quick note to let me know if I am correct about the cutter.
I have not seen a response from OP about how her efforts turned out.
Once again, thanks for all the help for us technically challenged !!!!
