Despite living in an urban area, not that far from London, mobile phone signal problems are a total pain in the neck, I have thought of going over to a landline at times in desperation.
Due to work on the masts in my area, both my numbers have issues today unfortunately, although they are on 2 different networks, they should be fixed at some point today.
I have a 3rd number with yet another network if you cant get through which is 07880 510604
