They don't block SIM cards. They block the phones based on their IMEI number. So you can't use this (blocked) phone anymore on any Turkish SIM card. You can still use the SIM card on another (not blocked) phone.

As soon as you have registered a SIM card to a phone, both are linked or paired and can only be used together.
