No auth provided- they said there is no need for a username or password, and the sim should be unlocked already--

EDIT--

 Is the problem that the APN =  broadband? I'm trying to find commands that can activate the profile:

Who is your provider ?

[therealcarbon]

AT&T

[ddefoort]

Hi, Did you ever get this working with AT&T if so can you post the solution, please?

[Georg Pauwen]

I remember that question, there was a typo in the chat script.

If you have a similar problem, post the configuration of your router...

[brett.stone]

I had the same issue with an MC7700 Sierra card and it came down to a few things that Cisco TAC had to help me resolve.  The first thing was that under line 0/0/0, you need a script dialer LTE and a modem InOut command.  We also set up a watchdog and a dialer; although I'm unsure if its needed or not.  Here a full working config (bare minimum).

Please do a show cellular 0/0/0 all command and paste the results so I can review.  There is a very specific IOS image which is needed for certain types of cellular cards.  Also, are you 100% positive you have a good known working SIM card because sometimes the issues are on the carrier side.

Yes It is 100% Working Sim issued by Vodafone Australia..

[brett.stone]

It looks like your config is fine, and you have the MC7304 Device Model which does not require a specific version of firmware; however you only have a really old IOS version 15.2 loaded and I would recommend upgrading to the latest 157-3m4b as that will flush out some bugs.  You are also missing some small code for a sub interface.  Please add this in.

interface Cellular0/0/1
no ip address
encapsulation slip

If you don't have smartnet and need access to the latest IOS, private message me and I'll provide you a link to download it.

[TJ81]

at the moment I'm etting following on debug 

*Jun 24 13:49:07.723: CHAT0/0/0: Chat script lte finished, status = Connection timed out; remote host not responding
*Jun 24 13:49:07.723: Ce0/0/0 DDR: disconnecting call
*Jun 24 13:49:22.723: Ce0/0/0 DDR: re-enable timeout

[brett.stone]

I’m willing to bet it is a provisioning issue at this point.  If you take the SIM card out and place it in another device such as an Ipad, laptop, or similar, do you get service?

[TJ81]

YES it is working sim
