Does anyone know if you can buy SIM-card the Chennai Airport itself? If yes, where is it sold? Also, I have been to Chennai twice before but I still haven't figured that one out. It's impossible to get around since I couldn't book Uber and all that and had to depend on my cousin. I hate to exchange money at the Airport itself, I feel like you have to bargain a lot with them and I am not good at that. Is there any reliable place where you can exchange money for a good rate?
