I'm buying a phone from Gumtree.
It's brand new and the seller advises that he won it at a competition through one of the 2 ISPs (Telstra, Vodafone or Optus) hence no receipts.
He provided me an IMEI number, but is there a way I can check this isn't a grey import phone and i'm being conned?

Also check if the phone is stolen or blocked:
