Hi there, Chieeee. Thanks for contacting us.
To unlock a cellphone, it has to be activated at least 12 months. It cannot be reported lost/stolen. If it complies with this requirements, you just have to get in contact with us over the phone or through private text message with the phone number and PIN to confirm and proceed.
Yes, I understand. A Boost Mobile cellphone would have to be used (or just activated) on the Boost Mobile network for the first 12 months. After that, it can be unlocked and activated with a different carrier.
