They might be free now but for how long?. You still need to pay for the installation + equipment and then must register to be able to watch their channels for free.

At the moment they provide their 15 channels as per http://www.dsmart.com.tr/?contentId=28 + anything that is FTA on TurkSat – get everyone to register with their service and get them used to it and then start charging, pretty smart for D-Smart spin
