No signal on Isle of Barra

[#1]

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.

Thanks for getting back to me @RobfromBarra 

There's an option to private message me if you go into my forum profile.
