How the "guarantee" works

We scrape and aggregate:

• SaveCompare
• MyMobiles
• CompareMyMobile
• HotUKDeals
• SimSherpa
• Provider official sites (giffgaff, iD Mobile, Smarty, Lebara, 1pMobile, Talkmobile, Mozillion, spusu)
• Reddit (r/UKFrugal, r/UKPersonalFinance)
• MoneySuperMarket

Only public, verifiable offers are listed. Fair use, contract length and network are always shown.

If you find a cheaper publicly advertised deal for South Yorkshire that we missed, open an issue — we'll add it immediately.
