Often when I go somewhere on holiday I buy a local sim card with some mobile internet on it (500Mb or something) to use in my phone (Google Maps, Wikipedia, Translation, Tripadvisor, etc.).
What is a good SIM card to buy?
I've had a look at the Turkcell and Vodafone sites, but my Turkish isn't very good and Google translate isn't really helping me.
Does anyone have a good idea? And how much would it cost me?
