How do I PM you? I get a signal at HS9 5XN - or should I say I appear to - but can not download or make calls signal is four bars plus 4g. The phone displays a message "calling" but nothing happens. The nearest mast to me at HS9 5UW I'm getting zero even if I park next to it. I do get a signal from a mast near HS9 5UY and can make calls and download. It's been like this for over a week now.
