You need to go to customs at dalaman, with a valid filght ticket, receipt, phone etc all in your name. At the moment cant find a way to get round that but am still trying, once customs have stamped the darn form, you then have to go to Mugla to a turkcell shop and they forward all the dubbish to Ankara and then you wait. Loverly.....ps ,make sure its a dayflight else customs closed....
