I have been using tata sky since 4 year ago I have got lots of experience with tata sky it is easy to operate than dish tv both are give great service on hd and non hd but with tata sky I got much experience. both are provide good service and installation process which is good.
In rainy season dish tv shows many time no signal than tata sky that time I have got worst experience with dish tv according to me in all department tata sky give better facility for experience tata sky costumer services immediate response is also so good, recharge cheaper, more channel at same recharge, In all the platform tata sky is one step forward with dish tv.
that’s the reason behind I will go with tata sky.
