just a warning as not everybody knows this..if you buy turkcell units to top up your phone as many people do. you build up a bank of free units that are accessed bye dailing *131 then hash button...you then can obtain the ammount of free credits you have..the other day friends of ours who travel over here frequently went into a turkcell shop in fethiye to obtain credits the man in the shop fiddled about with their phone out of sight behind the counter, they became suspicious and asked what he was doing , he made excuses left the shop and returned a few minutes later and charged them 25 ytl for the counters he had got. they were convinced they had been fleeced but not sure how...when they told us we checked thier mobile and found the free credits they had ,had been used. my mrs went to the shop they had been to , read the guy the riot act and got thier money back
