Cant help you on the 126 TLY, don't know what that is, but I use the 10 GB 3 months for 79 lira, used it for over 4 years now, of course if you are watching stuff on you tube or playing games on facebook of course it will run out before, but you do get informed 24 hrs before it goes. by the way I have people on my complex regularly coming to me asking if they can use my internet as their landline is down. I have tried to tell them on several occasions to get a dongle and save the hassle of turks digging up the roads and been without internet for months. but everyone to their own as the saying goes. hope this helps.
