Restoring giffgaff Service on iPhone
Turn Airplane Mode on, wait 15 seconds, then turn it off. This forces your iPhone to drop and re-register on the giffgaff network from scratch.
Power off your iPhone. Remove the SIM tray, take the SIM out, check the gold contacts for dirt or damage, then reinsert firmly. Power on and wait 2 minutes.
A full restart clears radio firmware errors that can cause No Service. Hold power and tap Restart. Allow 2 minutes for giffgaff network registration to complete.
Visit giffgaff's coverage checker or network status page to confirm there is no outage at your location. During outages, No Service affects whole areas simultaneously.
Go to Settings → Mobile Network → Network Operators → Search manually. Select giffgaff from the list. This forces re-registration when auto-search fails.
An unpaid bill, spending cap, or suspended account shows as No Service on your iPhone. Call giffgaff.com community (no phone support) from another phone or check the giffgaff app to confirm account status.
As a final step before requesting a SIM replacement, go to Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings. After reset, wait 5 minutes for giffgaff to re-register your device on the network.
