GiffGaff, the pay-as-you-go network run by the members with better than contract prices and no long contracts.!
You can also buy monthly Goody Bags for even better value in your phone and when you top up your account you will also receive FREE giffgaff to giffgaff calls and texts for 3 months.
GiffGaff also offer data gigabags for use in non phone mobile devices such as tablets, iPads and USB Dongles.
GiffGaff uses the O2 network, so your giffgaff SIM will work in any O2 or unlocked handset. Some handsets can be unlocked for free or a few pounds with a code off web sites such as eBay while others may have to be unlocked by the operator. For example Orange currently charge £20.48 to unlock a phone and if you are on a contract iPhone plan you could save this unlock charge after only 1 month with giffgaff! Some providers may unlock a handset for free under certain circumstances so its worth checking. You will also find that a decent unlocked phone will fetch more when selling it on sites like eBay.
