Sky customers can currently upgrade to Sky Go Extra for £1 a month for six months, marking an 80% discount on the usual price of £5.
The offer is open to existing Sky subscribers, and allows them to register up to four different devices on which to watch Sky on the go, compared with two devices with regular Sky Go.
That means each customer is able to register a smartphone, tablet, laptop and any other mobile device capable of streaming Sky, at any time of the day.
Furthermore, an internet connection is not always required, as subscribers can download their favourite shows to the device to watch at a later time, whether this is during a journey or in a place with no Wi-Fi or 4G.
The packages available with the app mirror those that the customer pays for with their Sky subscription, so those with Sky Sports and Sky Movies can watch the latest matches and films live or on demand, whenever they desire.
