There are some requirements to unlock a device:
-The device has not been reported as lost or stolen
-The device has been active on the associated account for at least 12 months
-The device must be powered on and in Sprint coverage with the original SIM card inserted.
We understand. So you wanted to activate that device with Boost Mobile and you unable to do so because you believed it was unlocked but it is not? ~AmyM25
