What is going on with the signal? I am in what used to be a perfect 4G area now I'm lucky if I get 2 bars on my signal strength. O2 say there is nothing wrong with their network so if that is true what's happened to the signal?
@Gaz124 See if there's anything in these guides to help you:
How can I sort out my network issues? - o2uk
Why do I have poor coverage indoors? (o2.co.uk)
I DO NOT WORK FOR O2
