I have a Sony Ericsson Z200 that I would like to sell on eBay. It's currently locked to Fido, but I do have another SIM card that I got with my new phone, so I can include that in the package. I know SIM cards are cheap, I guess the only redeeming value of it is that when you activate a new account, you get $50 of airtime credit on your account. Do I spend the $20 to unlock the phone and sell it like that without the SIM card, or sell the SIM card with it in a locked form? P.S. If this thread has been brought up before, my defence is that I don't have the search function, and there are far too many pages to go through.
