just a PC. window s XP. the dongle manufacturers website says current month usage is 4 gb but this is total usage for 2.5 months.
the Three website says nothing except that i ve run out of data
and 4gb is an exaggeration also
What dongle is it?
I have been using a Huawei K4201 (Vodafone branded but unlocked) for a while now and I can confirm that the usage counter in the dongle's web interface is exactly correct - as measured by my own tracking on the gateway server it is connected to here and also according to my providers' usage tracking (have to use o2 / giffgaff as that's the only signal I have).
Doing mostly text heavy browsing several hours a day, email and the occasional video I routinely use ~2GB a month including system / software updates for 3 machines, so your usage count sounds accurate to me.
I take it you purchased this plan: Broadband - Pay As You Go + 12. ?
Sounds like Three usage tracking is knackered to me.
