Despite ALL the signal strength checkers showing a good signal strength at my address I can rarely get my mobile to work. The signal varies all the time and is non existent most of the time and appears to be getting worse. An insider said that it was probably due to Virgin "piggy backing" EE.
My address is on a hill with only low height dwellings around.
However there is NO MAST at the top of the hill where one would provide excellent coverage over a wide area of the surrounding countryside.
The fact that it has worsened over the last 3 years is strange to say the least.
