If you’re anything like me, you _hate _the Vodafone Mobile Connect client - it’s buggy, unstable, and requires frequent reboots/restarts/taking-the-card-out-and-putting-it-back-in-again to make it work. What I only discovered today - although I should have known from ancient dial-up modem connections years ago - was that you can just use the regular ‘Network Connections’ facility of Windows. Just locate the ‘Vodafone Mobile Connect’ entry, right-click and select ‘Connect’ (I think this will only appear once you’ve installed the Vodafone software):
Easy-peasy connectivity. You can still track how many bytes have been uploaded/downloaded in the current session by turning on ‘Show icon in notification area when connected’ from the Connection’s Properties dialog. You’ll then see an icon in the system tray with a pop-up showing usage. Sadly, this is only for the current session, not the month as a whole - haven’t yet found a decent bit of software to do that (surprisingly).
