O2 UK customers should consider downloading and installing the My Network app on their device, as it serves as a one-stop application that gives you access to various handy features and important data. For instance, once installed and set up, you can use the app to view the network's 2G, 3G, 4G, as well as 5G coverage. This helps when you are deciding what kind of connection plan to get in a certain area.

The app also gives quick and easy access to the network's status in your location, alerting you if there are cases of maintenance or faults that may hinder your connectivity.
