It has promised almost all the best

I know that many people here in the Uk were changing their mobile network into O2 cause it has promised almost all the best that it can give its customers. I was also that one who was amazed by the amazing deals the O2 has given. I really love the offers that O2 was giving its subscriber! But wait! What was happening to their mobile phone coverage? But it seems that O2 is lacking signal here. I even find it hard to have my mobile phone near me cause I just have a signal in our room but when I left the room I don’t have any signal at all. So to those who want nor planning to have O2 as your mobile services please better check if your location is good enough for that network cause if not the promos that they have will not be the best for you.
