Same here.  ATD#DATA returns ERROR.

I don't think the UML290 supports this feature via the AT port.
VZAccess requests data usage via the WMC port using command 0x56, which
I haven't gotten around to reverse engineering yet.  In fact, VZAccess
doesn't use the UML290's AT port at all, just QMI and WMC.  So you're
kinda out of luck here, at least controlling it with the AT port.
