Unlocking Curve 8310

My friend gave me a 8310 that was activated with AT&T when he used it, I have service with sprint, however, there is no SIM card in the phone, what type of SIM do I need and how do i need to go about unlocking it to receive sprint service.

Re: Unlocking Curve 8310

Hi Matt and welcome to the Blackberry Forum


Sorry, but you can't, the Sprint network is CDMA, and the ATT Network is GSM.

If your friend made the pin release from ATT, you can connect the device (unlocking) on Tmobile for example. 

If I help you with any inquire, thank you for click kudos in my post.
If your issue has been solved, please mark the post was solved.
