O2's 5G coverage is strong and reliable in major cities and towns across the UK, as well as in many smaller villages – and more locations are gaining coverage all the time. However, you can only access 5G speeds with a 5G compatible handset and 5G data plan. 4G coverage from O2 stands at over 99% indoors (and out!).
