Detailed Review
Network Coverage & Speed
GiffGaff runs on the O2 network, which provides 99% population coverage across the UK. In our testing, we found excellent 4G coverage in urban areas and most rural locations. 5G is available in over 100 towns and cities, with average speeds of 150 Mbps.
Indoor coverage is generally strong, though some users report occasional signal issues in very rural areas or thick-walled buildings. Overall, the O2 network provides reliable connectivity for most UK users.
Pricing & Value
GiffGaff offers exceptional value for money. Plans start from just £6/month for unlimited calls, texts, and 1GB data. The £10/month plan includes 5GB data, while £15 gets you 20GB. For heavy users, unlimited data plans are available from £25/month.
Compared to major networks charging £30-50/month for similar plans, GiffGaff provides savings of 40-60%. The no-contract model means you can change or cancel anytime without penalties.
Customer Service
GiffGaff's community-driven support model is unique. Instead of traditional phone support, users help each other through online forums. Active community members earn "payback" credit for providing helpful answers.
While this keeps costs down, response times can vary. Simple questions get answered quickly, but complex technical issues may take longer to resolve. The online help center is comprehensive, and most common problems have detailed guides.
