So when we try to open it the phone still locked on the sprint so we came back to the store this lady that work on the sprint told us that is already UNLOCK but some phone are cant be recognize by other sim???? Oh really you call that unlock but you can put different carrier what do you think of us stupid fck u sprint. Dont buy sprint worst place
