What do I need to use 5G on an O2 SIM only deal?
You'll need a 5G-ready handset and to be in an area covered by O2's 5G network. The good news is that 5G is included on O2's SIM only plans at no extra cost, so there's nothing extra to add on.
Check O2's coverage map for your area, as 5G is still expanding across UK towns and cities.
Is 5G worth it, and will it drain my data faster?
5G brings much faster download and upload speeds and lower lag, which makes a real difference for streaming in high quality, gaming and tethering.
It doesn't use more data for the same task — a video uses the same amount whether on 4G or 5G — but the extra speed can tempt you to do more, so a generous or unlimited allowance pairs well with 5G.
