Forgetting the residency requirement for the moment,you need a telephone connection first.7days after that is connected you return to Turk Telecom and complete another similar contract for the ADSL connection.However,if your apartment is new and there are no existing connections you may find they will not connect unless there are between 20 to 50 lines needed.If its an old building/apartment etc it may be quite easy.Go and talk to them,but you will need a telephone number from the nearest home that is already connected for them to find where you are.There are a few english speakers in their office, but its still easier if you take a turkish friend.good luck
