giffgaff coverage
giffgaff doesn't own masts — it uses O2's network. Wherever O2 has signal, giffgaff customers should too. Coverage varies street by street and indoors, so check your home and work postcodes on Ofcom's coverage checker before you buy.
Customer feedback: official complaint figures
Ofcom only publishes complaint figures for providers with more than 1.5% of the pay-monthly mobile market, and giffgaff is not currently listed. That says nothing good or bad about its service — it simply means the official figures don't cover it. Read reviews from CompareDirect members or check independent review sites before you switch.
