APN field greyed out? Here is why
On Android: the field is locked by a carrier profile. Go to Settings → Network & Internet → Mobile Network → Access Point Names and tap Reset to Default (three-dot menu). On iPhone: the carrier bundle controls the APN — it cannot be edited manually. Contact your network to push an updated carrier profile, or insert the SIM in another phone to test.

APN values are case-sensitive — enter them exactly
Type every character exactly as shown — no spaces before or after, no capital letters unless listed. One wrong character stops mobile data from working. After saving on Android, tap the radio button (filled circle) next to the new profile to activate it.

2. A complete restart flushes temporary faults and locks in the new settings.
3. Delete the giffgaff APN and enter every value again.
4. A complete network settings reset clears Wi-Fi and Bluetooth pairings but brings giffgaff's defaults back.
5. Check the account side — SIM activation, account status and remaining allowance.
