The coverage checker for my postcode CM6 1BY says that I have good 4G service. However, I barely have a 3G connection possibly because I live at the bottom of a hill. How can I get an improved connection?
The mobile companies base their checkers on the centre of the postcode. If you click on the link below you will open the OFCOM checker which will allow you to check to the individual address. The results can be very interesting, they are where I live.
