NO!! if your gonna use a at%26amp;t prepaid sim card in a at%26amp;t unlocked phone, i wouldn't do it! people on ebay charge way more for an unlocked phone then they would a locked phone so if i were you, i would buy a locked one because your getting the same phone but a better price
An unlocked phone is so you could use a at%26amp;t phone on tmobile or other way around, not so you could use it with prepaid, you could do that anywayCan i use a att go phone sim card with any unlocked att phone?
it doesnt even have to be unlocked as long as its an at%26amp;t phone or cingular
