Daniel,
The isp has already given you all the necessary information you need. You need
to create a profile using this information.
RTR(config)#do cellular 0/3/0 gsm profile create 4 apn.com pap user1 pass1
!
RTR(config)#chat-script gsm "" "ATDT*99*#4" TIMEOUT 60 "CONNECT"
If you are not getting public IP address to you cellular interface, then your
PAP authentication is not working. You could use the debug ppp command to
debug the problem.
Yes you will need to connect a host to generate traffic.

Hello Daniel,
you can use
debug ppp negotiation
debug ppp authentication
to see what is going wrong
on a telnet/SSH session you need to give the command
terminal monitor
to see debug messages
post the debug output as a text file using the attach file option
A reference to HWIC configuration guide
see the section configuring a modem profile
cellular
<profile number>
this part is missing in your configuration
Hope to help

jennyjhon,
I don't understand what parameters the isp must to provide me to configure this line:
chat-script gsm "" "ATDT*99*#7" TIMEOUT 60 "CONNECT"
I mut to put "" ""ATDT, isp to provide me this?
ISP told me tha *99# is to stablish call, then how must to config chat-script gsm command?
Note: I don´t getting public IP addres, then I need to connect a host to generate traffic?

jennyjohn,
I configured this command but not work, then I verifed apn, user and pass and they are correct, debub ppp athentication and debug ppp negotiation don't display output (I have loggin console enabled).

Can you send the output of show cellular 0/3/0 all?
You have to enable the debugs, then on the cellular interface do a shut and then a no shut, then see if any pap authentication is taking place.

All its ok now, the problem was ISP because gave me error datas, with this line works fine:
chat-script gsm "" "ATDT*98#" TIMEOUT 30 "CONNECT"
