Thank for that Stan. I couldnt work out how it worked for the fraudster but this helped me make sense of it.

Fraudsters may try to convince you to return a phone to another address, so they can either intercept or receive it. For example, they may order a phone on your account, then contact you (pretending to work for Tesco Mobile) and say that it's been sent to you in error, and advise you to return it to a certain address.
