It's not possible from FixYa, sorry.

If your phone is locked then either try a new SIM (=new phone number) or if you wish to continue with the current SIM you must ask your network provider for a PUK code.

If your phone is blocked (blocking disables the phone handset when reported lost or stolen) then you must contact whichever phone company blocked the phone along with proof of your identity to have the block removed..
