5G is here

Fast, reliable and mobile. It’s time to 5G your life. The power of 5G gives customers a faster and more reliable connection, downloads without delay and buffer-free streaming, on the go. But it’s so much more than that.

The positive impact that 5G will have on the world around us is even more exciting. This new, more energy efficient technology has the power to connect buildings, transport and services in ways we’ve never seen; completely revolutionising everything, from the way traffic flows on our roads, to the way we receive healthcare.

Where can I get 5G?

Our 5G network now covers around 500 towns and cities, and we’re on target to cover 50% of the population in 2023. To see whether 5G has arrived in your area, visit our coverage checker.

We’re also working with major UK businesses and as part of cross-industry innovation projects, to test the potential capabilities of our 5G spectrum and new technologies as we start to build the 5G economy.

All our Pay Monthly plans come with 5G, so all you need is a 5G-ready device to get connected.

5G vs 4G

5G delivers faster speeds than 4G, giving you near-instant access to the things you love, and a more reliable connection even at the busiest times.

Faster speeds

Our 5G is around 35% quicker than 4G, which means you’ll be able to do everything you do now, but faster. Download a movie as you run for the bus. Enjoy stutter-free video calling when you’re out and about. And easily upload and email big files, while you work on the go.

Lower latency

Nearly everything you do online is affected by latency (the time it takes for a network to respond), so with 5G you’ll receive a more responsive internet experience, with near-instant access to the things you love.

In the future, ultra-low latency is going to be a game changer for highly sensitive jobs that require precise inputs and real-time feedback, like that important job interview or being the last one standing in a battle royale.

But where 5G really comes into its own is for our business customers. 5G will enable them to use our mobile network to do some pretty cool things with augmented and virtual reality, automation, robotics and much, much more.

Better network capacity

5G is perfect for when you’re at a crowded concert at an O2 Academy, watching a game at a packed stadium, or when working remotely. It’s designed so that thousands of people can stand in the same place and upload and download as much as they like.

And while 5G is being rolled out across the UK, 4G will keep getting better. In the last 12 months (June 2021 to May 2022), we’ve added extra 4G capacity network in almost 400,000 separate postcodes across the UK. That’s a lot of extra bandwidth!

Will 5G impact my health?

We’re excited about the benefits that our 5G network will bring for customers and businesses, but we understand there are some questions being asked about the impact on our health.

The WHO and the International Telecommunication Union (ITU) recommend that governments adopt the radio-frequency exposure limits developed by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).

In the UK, the Government has adopted these exposure limits developed by ICNIRP and mobile network operators are required to operate within these guidelines.

If you want to know more you can visit the World Health Organization or Mobile UK.
