And we are not Apple employees, just users like yourself volunteering to try and help the best we can. These forums are not official Apple support.

Contact your carrier for help with this. They are the only one’s who can unlock your phone.

No, we can't do it for you.

It's between you and the carrier that locked your iPhone.

FYI: Apple do not lock/unlock iPhone, only the carrier can officially unlock and if you qualify.
