Giffgaff is one of a number of MVNO’s entering the 4G market, but Giffgaff has certain advantages including a known name, a solid history as a 3G provider and low prices.
The network uses O2 for signal, so where O2 has 4G Giffgaff also has 4G. So right now it should have 4G coverage for over 70% of the UK population and that’s likely to reach 98% before too long. O2 customers also have a 4G signal 55.97% of the time according to OpenSignal, so that too is likely to be true for Giffgaff.

Giffgaff uses the 800 MHz (0.8 GHz) frequency for 4G. This is especially good at passing over long distances and through walls, but it doesn’t have as high data capacity as some frequencies, so doesn’t work quite as well in areas where lots of people are connecting at once.
Giffgaff doesn’t currently offer any cheap or inclusive roaming for data, texts or calls.
