Questions about the BT Mobile Extra Speed 4G add-on

What is Extra Speed 4G?

Our Extra Speed 4G add-on gives you faster mobile data speeds than our standard 4G. With the add-on, the maximum download speed can be as high as 60Mbps (megabits per second) rather than 30 Mbps on our standard 4G. It means you could download an app in as little as 3.5 seconds compared to seven seconds with standard 4G, or download a music track in 1.5 seconds compared to three. It should make using your smartphone a lot slicker with less time waiting for content to buffer or for apps to load.

Will I always get speeds of 60Mbps?
