This O2 SIM only deal is usually £16 per month, but saving over £126 by redemption (essentially you have to send off your bills at specified times), it’s effectively just £5.49 per month. Oh, and don't forget your £20 Quidco cashback!
The monthly O2 allowance includes 1,000 minutes, unlimited texts and 1GB of data.
