Hi. Here’s my situation: I work remotely, and I need to be online almost as soon as my flight lands. I need a stable mobile internet connection for work calls and messaging. I know that in the arrivals hall at Istanbul Airport, there are counters for all the local carriers, such as Turkcell and Vodafone. But many people say that prices for foreigners there are significantly higher than at their city offices. Does it make sense to buy a local SIM card right after landing, or is it better to wait until I get to the city and save some money?
