Your GiffGaff mobile data not working is not something you want occurring when you’re out and cannot find a Wifi hotspot.
It’s good to keep in mind that GiffGaff is reliant on the O2 network, so it’s best to first check your coverage to make sure you’re not out of the zone from a cell tower or that the network may just be completely down, in which case you would have to wait it out until they have fixed the problem.
At Easyfix, we don’t want you stressing over how or why your GiffGaff mobile data is not working, so we have created this simple guide for you to follow which you will be able to use every time you experience this problem on your phone.

- 5G is only available on GiffGaffs ‘Golden’ plan, whereas O2 offers 5G
