Fixing SMARTY Mobile Data on OnePlus
Go to Settings → Wi-Fi & network → SIM & network → Mobile data. Turn mobile data off, wait 10 seconds, then turn it back on. This forces a fresh data session with SMARTY.
Hold the power button and tap Restart. A full restart clears the radio stack and re-registers the SIM on the SMARTY 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 → Wi-Fi & network → SIM & network → Access point names and confirm the SMARTY APN value reads: smarty. Incorrect APN settings are the most common cause of mobile data failure.
Call SMARTY support on smarty.co.uk live chat or log into the SMARTY 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 options → Reset Wi-Fi, mobile & Bluetooth. This clears all saved network configuration and re-provisions SMARTY settings from scratch.
Visit SMARTY's status page or search 'SMARTY network outage' to confirm there is no service disruption in your area affecting SMARTY mobile data.

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