Some sprint phones have sim cards available. I'd probably check and see if the imei is flagged or not.

the phone can only be unlocked for international GSM use by sprint and only if the phone is activated on sprint network. If you can't use it on Sprint netowork, return it or re-sell, but first check with sprint if it can be activated. If it is blacklisted and cannot be activated you can still sell it for parts as "bad ESN" if the seller will not accept the return.
