I have been using Tata Sky from last 2 years.Earlier I was an Airtel DTH customer for 4 years however I have a pretty good experience with Tata Sky.Airtel gives no better services even though it is a popular brand. Tata Sky has really good service under extreme climatic conditions on other hand Airtel DTH gives flickering and annoying service even when there are Light Rains.Service providers as well as Ala carte benefits for Tata Sky are better than Airtel they offer good active games services as well as fun 2 learn services at affordable price . Airtel on other hand has a bit higher prices and their services are not as good as Tata Sky.Doing your monthly recharge is also a mess with Airtel even after your recharge they do not resume your services immediately which is truely annoying . Tata Sky on other hand provides better service and reminders before your due date and resume their services as soon as you recharge.However I would recommend Airtel if you wish to have good regional channels they have a good collection of regional channels as compared to Tata Sky.and if you are a foreign language geek then you must have Tata Sky. I would truly recommend Tata Sky over Airtel DTH.
