Um, what? I just signed up for fiber in Istanbul, lowest plan, 25mbit, at dirt cheap $11 a month — unmetered. Meanwhile my San Francisco apartment, Comcast charges me $67 a month for a 50mbit capped one.
While there is some variance in availability (just like any other country) Turkish infrastructure is generally first-world.

That’s more than Greece’s, and climbing towards Italy’s.
