For some crazy reason, I'm considering buying a SIM in Turkey, rather than using my perfectly good Vodafone UK SIM for my upcoming trip to Turkey.
There is a Vodafone store and a Turkcell store at the Istanbul airport, but I understand prices are much much cheaper outside the airport ($40+ vs < $5 in Istanbul.) If I am going to pay that much, I'll use my own equally expensive Vodafone UK SIM.
There is a a Turkcell shop near my hotel and I've read they have good coverage.
Has anyone bought a Turkcell SIM in Istanbul? Or a Vodafone SIM? Do you recommend it? How was your buying experience? What did you pay and did you get what you paid for?
