gd87 wont make or recieve calls
 

hi everyone im new here
can anyone help me iv recently bought a gd87 from a guy i thought was a mate, it was working fine. then all of a sudden it stopped from making or recieving calls.
i was told i would never get it working again?

i really dont know what to do?
can anyone plz help me i payed alot for that phone

cheers :(

Sadly, this sounds like a straight forward. Your "mate" has reported the phone lost / stolen. Take it abroad with you and flog it, or ask your "mate" for the money back.
