Cisco 1921 with 3G-GSM module test

Dear All expert,

I'm doing an PoC for ISR 1921 with 3G-GSM module test. I couldn't get the IP negotiation from ISP. From the debug logs i found CHAP authentication failure but the same sim card and similar configuration applied to ISR 819 model do not need to pass through this authentication stage. Pls advice me if you have ever came across this issue and comment if anything goes wrong with my config. Thanks and appreciated. My related configuration and debug output are below.

Related config:

===========

chat-script gsm "" "ATDT*99*1#" TIMEOUT 60 "CONNECT"

ip route 10.2.0.0 255.255.0.0 Cellular0/0/0

interface Cellular0/0/0

ip address negotiated

ip nat outside

ip virtual-reassembly in

encapsulation ppp

dialer in-band

dialer idle-timeout 2147483

dialer string gsm

dialer-group 1

async mode interactive

end    

line 0/0/0

exec-timeout 0 0

script dialer gsm

modem InOut

no exec

rxspeed 3600000

txspeed 384000

Debug PPP negotiation and Chat:

===========================

POC_1921_3G#p 10.2.0.2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.2.0.2, timeout is 2 seconds:
