I’ve been an O2 customer for about 5 years now and want to pass on some of my knowledge and experiences. Over the last ten years I’ve tried all different mobile phone networks at one time or another, including Three, T-mobile, Orange, and Virgin Mobile, plus I have worked for several mobile phone companies and so have a pretty good knowledge of mobile phones, tarrifs, etc, etc.
I hope you enjoy this blog 
Sean.
