Fixing Lebara Mobile Data on iPhone

Toggle mobile data off and on
Go to Settings → Mobile Service → toggle Mobile Data. Turn mobile data off, wait 10 seconds, then turn it back on. This forces a fresh data session with Lebara.
Restart your iPhone
Hold the power button and tap Restart. A full restart clears the radio stack and re-registers the SIM on the Lebara network.
Check Airplane Mode is off
Swipe down for Quick Settings and ensure Airplane Mode is not active. Even a brief Airplane toggle can clear a stuck data session.
Verify APN settings
Go to Settings → Mobile Service → Mobile Data Network and confirm the Lebara APN value reads: uk.lebara.mobi. Incorrect APN settings are the most common cause of mobile data failure.
Check account status with Lebara
Call Lebara support on 5588 (free from Lebara) or log into the Lebara app to confirm your account is active, your plan has data remaining, and no spending cap is applied.
Reset network settings
If data still fails, perform a network reset via Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings. This clears all saved network configuration and re-provisions Lebara settings from scratch.
Check for Lebara outages
Visit Lebara's status page or search 'Lebara network outage' to confirm there is no service disruption in your area affecting Lebara mobile data.

Frequently Asked Questions

Why is Lebara mobile data suddenly not working?

Sudden Lebara mobile data failure is usually caused by one of four things: account suspension or spending cap, a temporary Lebara outage, APN settings corrupted by an update, or Airplane Mode having been toggled. Check the Lebara app first, then your APN settings.

Does restarting fix Lebara mobile data?

Restarting your iPhone fixes mobile data in approximately 40% of cases. A restart clears the radio firmware and forces a fresh Lebara data session. If it does not fix the issue, the cause is APN settings, account status, or a network outage.

How long does Lebara mobile data outage last?

Most Lebara mobile data outages are resolved within 2–4 hours. Major outages may take longer. Check Lebara's status page or social media for live updates. If there is no outage reported, the issue is specific to your account or device.
