Will also work with Giffgaff and Tesco Mobile, as it is locked on O2.
Cost 0 and £1 profit: Nokia 100 £1 + O2 credit £10 - £5.05 TCB - £6.25 sold credit (get pounsback.co.uk)
Topcashback tracks to £5 for this (it tracked in 1 hour in my case!) so a phone and £10 credit for just £6!
Nice phone for £1 (or £11 including the £10 top up).
Just put the SIM in and you will immediately receive the £10 credit (no other action required for activation).
