When you have our IPTV Extra Package subscription code, you can buy Sub-Device code(s) on the 2nd/3rd/4th Devices for your family!

Sideload is commonly referred to as “jailbreaking” the tool.
Don’t worry. With this tutorial, you can easily sideload additional AirTV Extra Sub-Device on Firestick using the Downloader application. The Downloader app is the best sideloading app for Firestick.
