Reasons to choose Three Mobile

Built for today’s internet world
The Three network has only ever used 3G technology from day one so it was built for surfing the internet at great speeds. This means that they are ahead of other networks and for you means you can get online faster in more locations.

The best 5G!
Three have big plans going forward. In 2019 they announced that they have acquired more 5G spectrum than any other UK mobile network. In plain English this means that they are aiming to build the biggest and fastest 5G network.

They wont be charging extra for this either. So, all you need is a compatible handset and be in a 5G coverage area. 3G and 4G will still be available too.

HD call quality
We all know how annoying it is when a mobile phone call is not 100% clear and keeps breaking up. This happens a lot less with 3 as they use the latest in HD voice technology. In short this means more of the calls you make sound like you are stood right next to the person you’re talking too.

No shock data charges
As time goes on, more of us are using our phones to get access to the internet. To take away the worry of sky high data bills, Three have introduced unlimited data on many of it’s SIM Only Plans. This is nicknamed All-You-Can-Eat-Data. When they say unlimited they really do means this. So you can YouTube and Facebook to your hearts content!
