5G is the fifth generation mobile network, and promises to banish lag time and latency, with unprecedented speeds and more reliable connectivity than ever before.

O2 is the latest network to join the 5G revolution, with coverage in most major UK cities, and plenty more coming over the course of 2020. Take a look at our guide below to find out more about 5G on O2.

What is 5G?

The next step up from 4G, 5G is the newest mobile network to roll out across the UK. It promises a dramatic increase in speed, along with several other improvements, like heightened security, delay-free downloads and uninterrupted HD streaming.

Using higher frequencies on the radio spectrum, 5G can achieve this whether you’re in a remote, rural area or a densely populated

Where can I get 5G on O2?

O2 has plans in place to have 5G operating successfully in over 50 different locations by the summer of 2020; Aberdeen, Bournemouth, Windsor and Warrington are just a few of the new locations which can expect coverage. You can find a full breakdown of current and upcoming areas with 5G coverage over on the O2 website.

How do I connect to 5G?

To enjoy all the benefits of O2’s 5G network, you need a 5G-ready handset, and 5G contract – plus you’ll need to be in an area where 5G is available.


Once you’ve got this sorted, connecting to 5G couldn’t be easier. When you’ve chosen your tariff, just switch on your new handset and pop your 5G SIM inside it – you can scroll, swipe and stream as much as you like.

Which 5G handsets can I buy on O2?

There are several top-of-the-range 5G handsets which are currently available on O2, like the Samsung Galaxy A90 5G and the Samsung Galaxy Note 10 Plus 5G.


Both of these smartphones are celebrated for offering an immersive viewing experience; the Galaxy A90 has an impressive 6.7-inch display, and the Galaxy Note 10 measures in even bigger at 6.8-inches. The smooth streaming and swift downloads that 5G promises will be a great advantage on both of these handsets.
