Re: Your phone works on electricity
but it's a LOT of phone for £230...
Indeed. Or shop round for deals on last year's top models on contract. Just taken out a contract on Galaxy S5, £11 a month over the price of a sim only bundle, and £40 up front, so £304 but paid in fairly painless instalments over two years. And if I had been quicker I could have avoided the £40 up front.
I really like the idea of sim-free phones far more than the contract model, but I've always found being careful and looking to buy last year's top models always trumps shelling out £200-300 for a credible contract free handset.
