Compared to 7 years with f2s and usage figures around 10 GB per month I've been surprised to find on changing to BT the usage has increased dramatically.
Nothing has changed here and although I'm now on a 12 day review with them, I've been using the TBH usage tester and find its figures are about a 5th of BT's usage metre.
While the test is on, my sons Xbox usage and my streeming usage has been curtailed so we seem to be using around 1.5-2.0GB per day for sending emails and visiting the web, which in my sons case is mainly facebook and twitter.
any constructive suggestions anyone.
