as i undeertand it,as have been in a few phone shops today in fethiye, you will have to register the phone with the turkish phone company turk telecom, you will not get it deducted of your sim cards as they are differnt companys, you will have to go in with your phone before the 13th to the telecom office and pay them 5ytl after that all phones that are not registered will not work here with a turkish sim card...unfotunatley nobody seems to have told the turk telecom office in fehiye how to go about this, am having another t.i.t. moment..this is turkey!!
