There are a few reasons your data might not be working:
Switch off the device, remove the sim and give it a little clean, pop the sim back in and switch the device back on.
Check to make sure your data is switched on in your phone settings by heading over to settings > searching 'data'.
You might have run out of data in your plan. Or have no credit. Pop over to my giffgaff to check your plan or credit balance.
Check the network status and coverage in your area. There could be issues with a mast or poor coverage affecting your data.
If calls and texts are working for you then there might be an issue with your internet APN settings. Have a look at our guide with the correct APN internet settings.
If you're abroad, make sure you have enabled your data roaming. If that doesn't fix it, try to perform a manual roam.
