Fixing O2 Mobile Data on Motorola
Go to Settings → Network & internet → toggle Mobile Data. Turn mobile data off, wait 10 seconds, then turn it back on. This forces a fresh data session with O2.
Hold the power button and tap Restart. A full restart clears the radio stack and re-registers the SIM on the O2 network.
Swipe down for Quick Settings and ensure Airplane Mode is not active. Even a brief Airplane toggle can clear a stuck data session.
Go to Settings → Network & internet → Mobile network → Advanced → Access Point Names and confirm the O2 APN value reads: mobile.o2.co.uk. Incorrect APN settings are the most common cause of mobile data failure.
Call O2 support on 202 (free from O2) or log into the O2 app to confirm your account is active, your plan has data remaining, and no spending cap is applied.
If data still fails, perform a network reset via Settings → System → Reset → Reset network settings. This clears all saved network configuration and re-provisions O2 settings from scratch.
Visit O2's status page or search 'O2 network outage' to confirm there is no service disruption in your area affecting O2 mobile data.

Frequently Asked Questions
Why is O2 mobile data suddenly not working?
Sudden O2 mobile data failure is usually caused by one of four things: account suspension or spending cap, a temporary O2 outage, APN settings corrupted by an update, or Airplane Mode having been toggled. Check the O2 app first, then your APN settings.
Does restarting fix O2 mobile data?
Restarting your Motorola fixes mobile data in approximately 40% of cases. A restart clears the radio firmware and forces a fresh O2 data session. If it does not fix the issue, the cause is APN settings, account status, or a network outage.
How long does O2 mobile data outage last?
Most O2 mobile data outages are resolved within 2–4 hours. Major outages may take longer. Check O2's status page or social media for live updates. If there is no outage reported, the issue is specific to your account or device.
