Configuring Cisco881G-K9 cellular interface

Hello. I have an issue regarding using cellular interface on cisco 881G. The 3G module is Aircard 504. SIMcard is working on other devices, it have obtain IP address from mobile operator. But on cisco881G it doesnt work.

Here is config:

cellular 0 gsm profile create 1 m2m

chat-script 3G "" "ATDT*98*4#" TIMEOUT 30 CONNECT

interface Cellular0

ip address negotiated

ip nat outside

ip virtual-reassembly in

encapsulation ppp

dialer in-band

dialer pool-member 2

async mode interactive

interface Dialer1

ip address negotiated

ip virtual-reassembly in

dialer pool 1

dialer idle-timeout 0

dialer string 3G

dialer persistent

dialer-group 1

no cdp enable

line 3

exec-timeout 0 0

script dialer gsm

modem InOut

no exec

transport input all

ip route 0.0.0.0 0.0.0.0 Dialer1

But cell interface still in inactive mode

Test-router#sh cellular 0 profile

Profile 1 = INACTIVE*

--------

PDP Type = IPv4

Access Point Name (APN) = m2m

Authentication = None

Username: , Password:

Profile 4 = INACTIVE

--------

PDP Type = IPv4

Access Point Name (APN) = m2m

Authentication = None

Username: , Password:

* - Default profile

and there is no ip address obtained. There is no authentication configured on mobile operator.

What can i do to solve the problem?
