5G is here

Every generation has its moment to write their chapter in history. This is the time to do great things. It couldn’t be more exciting seeing what 5G will make happen.

Our 5G network will empower the 5th Generation.

The power of 5G on personal and business devices will give everyone a better and more reliable connection in extra busy places, delay-free downloads and buffer-free streaming. But it’s 5G’s impact on the world around us that’s even more exciting. This new 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 health care.

Where can I get 5G?

We now have 5G in parts of most major UK towns and cities, as well as lots of smaller towns and villages. To see whether 5G has arrived in your area visit our coverage checker.

Our rollout will initially target those towns, cities and places where our customers need it most, such as transport hubs, key business areas and entertainment and sports venues.

We are also working with major UK businesses and as part of cross-industry innovation projects, to test the potential capabilities of the technology as we start to build the 5G economy.

If you’re on an O2 custom plan, you can upgrade to a 5G phone when the time’s right for you.

5G vs 4G

5G delivers faster speeds than 4G, a lower latency and improved capacity and reliability.

Faster speeds

Much, much quicker than 4G, which means you’ll be able to do everything you do now, but faster. Download a full movie as you run for a train. Enjoy perfect video calling when you’re out and about. And easily upload and email big files, while you work on the go.

Lower latency

Lower latency (the time it takes for a network to respond) is going to be a game changer for highly sensitive jobs that involve minute inputs and real-time feedback. Things like remote surgery, a critical video conference or being the last one standing in a battle royale. 

In the future 5G will have the bandwidth to comfortably handle augmented and virtual reality, giving workers the chance to train in real-life situations without putting themselves in danger, or use a VR headset to receive real-time instructions. Away from work you could use VR to watch a gig as though you’re in the front row, or see a try being scored through someone else’s eyes.

Better network capacity

5G is perfect for when you’re at a packed concert at an O2 Academy, watching a game at Twickenham 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.

While 5G is being rolled out across the UK, 4G will keep getting better, as we continue to spend £2 million a day on our network.

And adding 5G to our already award winning network will help us deliver higher speeds, increased reliability and improve capacity where our customers need it most.

What is the difference between 4G and 5G?

5G is the next generation of mobile networks, providing faster download speeds and coverage when lots of people are using the network at the same time. 5G will improve the service you get with 4G, making it easier for you to stay connected when it matters most.

5G and 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.
