About GiffGaff
GiffGaff is an award-winning UK mobile virtual network operator (MVNO) that operates on the O2 network, offering 99% UK coverage and the same 4G/5G speeds as O2 at lower prices. Founded in 2009 as "the mobile network run by you," GiffGaff is now the third-largest MVNO in the UK and has won Uswitch Network of the Year five consecutive times. The name "giffgaff" means "mutual giving," reflecting the brand's unique community-based model. Members help each other with questions via an online community (earning payback points), and customer feedback directly shapes how the network evolves. This model keeps costs low and customer satisfaction high - GiffGaff has ranked #1 in OFCOM's mobile network customer satisfaction survey. GiffGaff offers flexible SIM-only plans with generous data allowances - from 20GB for £10 to 100GB for £20 - all on rolling 1-month "goodybags" with no contracts. The network supports 5G on eligible plans and offers eSIM support for modern smartphones. Grocefully helps you compare GiffGaff SIM card prices at UK supermarkets including Morrisons, making it easy to grab a SIM while doing your grocery shop.
