TataSky is one of the best and oldest D2H service provider in India.It is low cost, has attractive channel packages and satisfactory customer support.I always prefer Online chat with Customer care for any issues with Connection as it is easy and has to wait for less time as compare to phone support.It has good picture and sound clarity.I am using TataSky since 2006, I had used other DTH also but I found TataSky is best and economic.Unlike other DTH provider it has very useful online customer portal which has almost every features required by users.TataSky has good signal coverage than other DTH provider.But beware of **free set top box upgradation**, TataSky customer care executive call me several time for free upgradation of set top box as I was having old set top box which does not support MPEG-4, I returned old set top box which cost me approx 7000 INR, which was very much fast as compare to the MPEG-4 box which they gave me.The MPEG-4 set top box very worst, very slow to start, takes time to open channel, most of the time it doesnt detect the smart card it is very frustrating, they are providing very cheap material set top box which has only 15 days warranty.Dont upgrade the free one set top box, rather exchange old one with HD set top box.
Overall it is Good DTH, but beware of the free Set top box.
