about a week ago I contacted three customer service to cancel my mobile broadband contract with three this was to do with the fact that signal quality was bad in my aria or so i thought however I was put through to some one from the tech service he explained that the 4G home hub device is able to pick up a better signal as it runs on somthing called the L spectrum witch is avalibe in my aria when I got the home hub I set it up near a window and the internet has been fine ever since as well as the 4G home hub there are a number of phone that also run on the new L spec signal so if you are able it might be worth upgrading to a phone that can pick up the L spec signal.
just type in three L spec into google if you want to know more
