Every few years mobile technology improves and these leaps in capability are called ‘generations’ – that’s what the ‘G’ in 3G and 4G stands for.
So 3G is the third generation of mobile networks. It was the first widely-available technology that allowed us to connect to the internet through our phones.
4G is the fourth generation of network. It delivers internet like 3G, but gives significantly faster speeds and better connections. This means tasks like streaming HD video and downloading apps happen much quicker than with a 3G connection.
The availability of 4G is limited but constantly increasing. By 2020, 5G will start rolling out – delivering even faster speeds than 4G.
If your phone can use 4G networks, make sure you enable your connection in your phone’s Settings menu.
