Since Turkey's mobile phone legislation is a pain in the ass, I'm considering renting a 3G/LTE Wifi hotspot on the two stopovers I will have there in February.
Is there a company which could rent me one at Istanbul airport? If not, maybe I can find such a service in the center of the city?
Technically I could just buy a sim-card and discard it later, but my 24-hour stopovers are over 3 weeks apart so it would be impossible for me to get Internet on the way back, since my IMEI would have been blocked by then.
