Money Mensch: Cash in your iPhone for £200
Millions of people bought iPhones from o2 when it launched a few years ago, and many of those phones are now out of contract.
Yet you could still be paying a hefty £30-£45 per month tariff. But there is a simple way to slash this.
Sign up to another year's contract, still with o2, and for £15 a month you get 300 any time, any network minutes plus unlimited texts and data - the same you would pay £35 per month for if you simply carried on with an old contract.
Technically this is a 'SIM only deal' but forget that; you don't need a new SIM, just call up and ask to be transferred to the SIMplicity package and it happens instantly.
You could sell your iPhone for around £200
Alternatively if you are planning on upgrading or ditching your iPhone you can sell it at speed for around £200.
