3G service on 1941W

Hi friends

I am setting up 3G service on 1941W router.  I know there were few threads that I came across regarding this issue where the new modem locks you to use only SLIP encap on your cellular interface. Even following those different threads, unfortunaley I could not get this issue resolved. All I see the following message

*Jan 29 05:07:33.255: Ce0/1/0 DDR: Attempting to dial hspa-R7

*Jan 29 05:07:33.255: CHAT0/1/0: Attempting async line dialer script

*Jan 29 05:07:33.255: CHAT0/1/0: Dialing using Modem script: hspa-R7 & System script: none

*Jan 29 05:07:33.255: CHAT0/1/0: process started

*Jan 29 05:07:33.255: CHAT0/1/0: Asserting DTR

*Jan 29 05:07:33.255: CHAT0/1/0: Chat script hspa-R7 started

*Jan 29 05:07:33.255: CHAT0/1/0: Sending string: AT!SCACT=1,1

*Jan 29 05:07:33.255: CHAT0/1/0: Expecting string: OK

*Jan 29 05:07:48.255: CHAT0/1/0: Timeout expecting: OK

*Jan 29 05:07:48.255: CHAT0/1/0: Chat script hspa-R7 finished, status = Connection timed out; remote host not responding

I will paste the config andother details below related to 3G and hope someone can point me in the right direction.
