The O2 is selling over priced phones. I was 5 years with them and i just regret that I upgraded for the I phone pro 250gb with them. just for device they asking for 1279 which is 80 pounds more like from original apple store. after 5 years i just realised how they making money everywhere and cheating the customers. for example in my five years with them they always overcharged me despite the fact that i had a cap on calls data and messages so it should be 0 extra pay but now when Im checking invoices they always did 5-6 pounds more. don't sign any contract with them never !!! there is much better choices .... and the sales managers are not polite at all... they just want your money and thats it ... don't want to know how much i over paid them and all those offers are overpriced ....
