You don't have to buy refurbished buy out of style Mobile phones. I got one from Car phone Warehouse for my hubby and it was half the price. Also, has a Sim only so no hefty monthy bills. I wish we had done this years ago! He has saved hundreds!
I have had my present mobile phone for about 4.5 years. So no contract for a new phone saving me hundreds of pounds and have a great SIM onlynmonthly from Smartly.
