Follow these steps in order — most issues are resolved by step 1 or 2
Quick checks before resetting giffgaff APN settings
Before changing any settings, visit the giffgaff APN hub or check a third-party site like Downdetector to confirm whether there is a known giffgaff outage in your area. If the network is down, you simply need to wait for giffgaff to restore service — no settings changes will help during an active outage.

Step-by-step giffgaff data fix on Android and iPhone
Pull down your notification shade and tap Aeroplane Mode to enable it. Wait ten seconds, then tap again to disable it. This forces your phone to drop its current connection and reconnect fresh to the giffgaff mast. This fixes the majority of temporary signal and data issues.

Escalating persistent giffgaff data issues to support
Hold the power button and select Restart. A full restart clears the modem cache and re-registers your SIM on the giffgaff network. This fixes many data and signal issues that toggling aeroplane mode does not resolve.

Step 4 — Re-seat your SIM card
Power off your phone completely. Use a SIM ejector tool or a straightened paperclip to open the SIM tray. Remove the SIM card, inspect the gold contacts for dirt or corrosion, and gently clean them with a dry cloth if necessary. Reinsert the SIM firmly and power the phone back on.

Step 5 — Check your APN settings
An incorrect APN is a common cause of mobile data not working even when you have signal. Go to Settings → Mobile Network → Access Point Names and verify the APN values match the giffgaff recommended settings. Visit the giffgaff APN hub for the correct values, or search this blog for the giffgaff APN guide for your specific device.

Reset Network Settings will delete all saved Wi-Fi passwords
This step also removes all Bluetooth pairings and VPN profiles. Make a note of your Wi-Fi passwords before continuing. Only use this as a last resort after all other steps have failed.
Step 6 — Reset network settings
On Android: Go to Settings → General Management → Reset → Reset Network Settings. This restores default APN settings, clears saved Wi-Fi networks and resets Bluetooth — it does not delete your apps or personal data.
On iPhone: Go to Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings. Your iPhone will restart and reconnect to giffgaff with default settings.

Have your account number and phone IMEI ready (dial *#06# to find your IMEI). Visit the giffgaff APN hub for contact details.
giffgaff mobile data may stop working due to an incorrect APN, a temporary network outage, an expired data plan, or a SIM issue. Follow the steps in this guide to identify and fix the cause.
