Been on vacation since Sept 5th with Exceed modem, computer and router all unplugged. My data resets on the 20th of every month. Just checked in to this site on my tablet and saw that I’ve "used" 1.6 gigs of data. Wondering how this is possible with everything unplugged?
Probably because the usage meter can't synchronize with the powered off modem - would be the first thing to check on returning home and powering on the modem unless you see it climbing from afar before then.
