Boss - Unless you have your phone activated on some network ie - AT&T You won't be able to make calls. You have to call them up and give them your ESN or HEX so they can register your phone on the network. If you pull the battery or have the box the sticker on the back or on the box should have those ESN HEX,DEC on it. The phone doesn't know where to connect to because of this. Theres also a chance that AT&T won't allow that phone on there network, because it's from Sprint and uses CDMA/GSM. It doesn't hurt to try though. Just call up your carrier...AT&T and see if they will activate it on there end...and hopefully you already have an account with them. If they are able to activate it you may also need to get a data plan...Just call them and see...Good Luck.
