Just thought I'd let you know that after suffering 5+ years of broadband coming in at a whopping 1mbs due to where we live (rural Scotland), an affordable solution from EE seems to be working.
A 4G router with an external antennae is giving us approx 30mbs. £60pcm for 200GB of data, £100 one off fee for installation.
Very impressed. (I don't work for EE btw)
