WMWiFiRouter triggering charges?

[Kalnel]

I've been using WMWiFiRouter for a few weeks now, and I noticed today that on my Verizon "My Current Usage" page, it is now showing a listing for "Domestic Mobile Broadband Connect." Although it shows my usage as 0.00, I wonder what has made this appear all of the sudden. On the My Plan page, it doesn't show Mobile Broadband Connect as being activated (at least as far as I can tell). Interestingly, on the data usage page, it is missing any readings for Wednesday or Thursday of this week, even though it has data usage recorded for yesterday. I don't think I've used so much data that it would have prompted any red flags -- I'm well under 400MB in the third week of my monthly billing cycle -- but I'm curious if they're now detecting/charging for WMWiFiRouter use.
