USB sierra aircard 320U

Dear all,

I have a USB sierra wireless aircard 320U i am using a EE sim card this sim is enable and working on iphone.
when i plug it i can see the linux kernel drivers are loaded and ifconfig -a shows wwan0
also i can see /dev/ttyUSB0,/dev/ttyUSB1,/dev/ttyUSB2,/dev/ttyUSB3 character files.
My hardware details Beagle bone black with android kitkat running linux kernel 3.8.13.

MY PROBLEM:
i cannot see any IP address assigned to wwan0. after a lot of search i see that the modem needs to be configured using AT command so that IP address is assigned and i would be able to access the internet.

NEED HELP:
can somebody please explain me what configurations i need to do in order to see that an IP address is assigned so that i can access internet.

Regards
Nick
