Checking for network issues

Struggling to make calls or send texts? Can’t get your mobile data working? Play the video for tips on getting connected.

Still having problems with your signal? Get online with O2 Wifi. We’ve got thousands of free hotspots all over the country for you to use when you're out and about.

If you haven't already, take a look at our Live Status Checker to see if there are any faults in your area. If something comes up, it means we're already working on fixing it, and you’ll be able to register for updates.

We keep tabs on all status checks, so if lots of people in your area are using the Status Checker, we'll know there's a problem. If someone you know is also having issues, get them to use the Status Checker too.

You can try fixing the problem yourself by switching your phone off and on. If this doesn't help, try selecting the network manually, using your device’s settings.

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 no issues show up and your phone and sim seem to be ok, keep an eye on the Status Checker for updates (these may take up to an hour to appear).
Once the live status page shows a fault has been fixed, you might need to turn your device off and on to refresh your network connection.

If you want us to look into your network issue:

  • You can contact us on Facebook or Twitter, and let us know that you've already done the above checks.
  • If you’re using a smartphone you can report the issue via the My Network app.
  • If you prefer to speak to someone, call 8002 from an O2 business mobile.

Phone or sim problems

If your phone is faulty, make sure it's backed up, try a hard reset and check your software is up to date. If that doesn’t help, you can make an appointment with an O2 Guru.

For problems with your sim, pop into your nearest O2 store. They can give you a new one for free.
