So Is GiffGaff Naff?
No, and here's why. GiffGaff was launched in 2010 and has already picked up industry awards and it also gives part of its profit to charities which is cool.
GiffGaff means "mutual giving" in Gaelic which is fitting for a community run virtual mobile network.
Virtual networks don't own infrastructure instead they piggyback their services onto a real mobile phone network, GiffGaff runs on O2.
With no hardware overheads and because the service is run by a community GiffGaff goodybags offer some of the cheapest pay-as-you-go (PAYG) deals around.
Join the GiffGaff community and participate in their forums and you can earn cash or phone credit rewards.
