How to enable 4G on giffgaff

giffgaff 4G APN settings

The APN settings for 4G on giffgaff are the same as the standard mobile data APN. Your phone should use 4G automatically once it is enabled in your network settings. If 4G is not appearing in the status bar despite being in a covered area, try toggling aeroplane mode, restarting your phone or resetting your APN settings to the giffgaff defaults.

💡
Fastest way to apply new APN settings
After saving, turn aeroplane mode ON for 10 seconds, then turn it OFF. This forces an immediate network re-registration — quicker than a full restart and equally effective.

Troubleshooting giffgaff 4G problems

4G not showing: Check your plan includes 4G. Ensure your device supports 4G. Verify you are within giffgaff 4G coverage. Go to network settings and set the preferred network type to include 4G.

4G slow: 4G speeds vary by location, network congestion and signal strength. Move to an area with a clearer line of sight to a mast. Ensure no background apps are consuming data. Contact giffgaff if speeds are consistently poor in your area.

4G connected but no internet: Check APN settings are correct for giffgaff. Reset network settings. Try switching to 4G, testing mobile data, then switching back to 4G.
