BT Openzone / Wifi does not use any of your allowance.
On my connection the TBB Speedtester uses around 150MB down and 15MB up. So, once perday will mean in the order of 4.5 to 5 GB which would equate to half your monthly allowance. But if you connection is significantly slower then the volume will be less.
Open Task Manager and note down the total volumes transfer up and down then run a speed test and check the volumes after. Than will give a good estimate of the down & up volumes for a single test.
