The My Network app lets you check the status of our network at any UK postcode. So if we’re having any outages or issues in the area, you’ll be able to find out. Having problems with your coverage? You can use the app to let us know about any issues you’ve had. And you can test your upload and download speeds too.

When you let us know about any problems with our coverage, we use the information to improve our network and understand how you use it.

No. You don't need to sign in to use the app. 

You might be able to fix the issue yourself. Try:

• turning Airplane Mode on, then off again
• charging your battery – a low battery can affect how well your phone connects to the network
• selecting the network manually in your settings, and making sure data is switched on
• checking your device is running off the latest software version
• checking your sim is 4G/5G enabled – if it’s not, you won’t be able to connect to our data network.

If you’re having issues in different areas, try your sim in a different O2 device. If the problem stops, there’s an issue with your device. And if a different O2 sim works in your device, then there’s a problem with your sim.

If your device and sim seem to be okay, keep an eye on the My Network app. It can take up to an hour for updates to appear.

Need help with any of these tips? Check out our internet and network coverage troubleshooter. Just choose your device and follow the steps.

If it turns out that your device or sim is the problem, contact us and we’ll be happy to help.
