What is 4G?
Back in the day when all we wanted to do was call or text, we used the 2G network. Then came 3G, which was better for using the internet on your phone - this is what most phones currently use.
The way we use our mobiles is changing. We are watching more videos, playing more games. And streaming, tweeting and browsing more than ever before. 4G will help make a world where we'll be able to use our digital devices in new and exciting ways. We can't wait.
