You have to find who the original owner is. He should be the one to request for unlocking. OR if you know his personal info, you can request it via 211 toll free using any globe line.
Usually, globe will ask the ff:
Once you know those, you can request it. NOTE THAT THE PLAN MUST BE STILL IN SERVICE AND NOT PERMANENTLY DISCONNECTED. Once disconnected, globe won't unlock it.
Oh, okay. Will try to find the first owner.
