Airtel Digital TV Upgrade from SD to HD Set-Top Box Before we move on to the upgrade to Airtel Xstream Box, firstly we would address the SD Set-Top Box users who are not even enjoying HD services. For these subscribers, Airtel Digital TV is offering an option to upgrade from the SD Set-Top Box to the HD Set-Top Box. Now to do this, the subscribers will have to pay Rs 699 instead of the total amount of a brand new HD Set-Top Box from Airtel Digital TV. But, the subscribers should also note that in addition to this Rs 699 charge, they would also have to pay Rs 150 engineer visitation charges to Airtel Digital TV, so that the engineer will be able to set up their new HD connection.

Although the upgrade to Airtel Xstream would be a costlier than the one from SD to HD, subscribers who are willing to consume content on OTT applications will definitely enjoy the Airtel Xstream Box. However, for the subscribers who are using Airtel Internet TV, the upgrade might not be worth it as they might be getting almost all the features of Airtel Xstream TV on their Set-Top Box. So, talking about the pricing of this upgrade to Airtel Xstream Box, the existing Airtel Digital TV subscribers will only have to pay Rs 1,999 in addition to the Rs 250 as engineer visitation charges to the company. This means, that subscribers would almost be making a saving of Rs 2,000 on the Airtel Xstream Box, since, for the new users, the Airtel Xstream Box retails for Rs 3,999.
