I recently bought Airtel digital TV .Airtel comes first when it comes to Mobile telenetworks and digital TVs .There are numerous HD channels available in My Airtel Digital TV .And the best thing I like about Airtel is that it is cheap .It came with a hd set top box, a power cable, an hdmi cable and a universal remote .I think if you have a good 4k TV then take my suggestion and go for Airtel digital TV .it cost me around 1800 rupees .It has the best customer service and best sound and picture quality.Airtel has a wide range of channels to choose .Like if you are a sports fan and you want the best experience by watching sports then You can buy the package separately .If you are more interested in watching movies and Series then you can opt for entertainment package.There is also channels for adjusting your favourite channels .You can also Record the entire TV serial in one go through Usb but you have to subscribe it separately .Airtel is lot better than Reliance, Dish TV and Videocon D2h .But since I am a sports fan I opted for Airtel .It’s up to the user .Thanks for reading this review .Have a nice day .
