No, that looks correct.  Also make sure that your WWAN interface is set
to "NOARP" with "ifconfig wwan0 -arp" or something like that.  Also,
instead of doing AT^DHCP? try simply running a DHCP client on the
interface after AT^ndisdup returns OK.  We've seen some devices that
don't seem to work correctly with static IP from ^DHCP but do work when
you run dhclient on the interface.
