Modem won't connect to internet

[matt_modem]

I have a WE-826-T2 with the most recent version of WIFix Goldenorb connected. It is fitted with a Sierra Wireless Airprime MC7700 modem and a SIM card with service from AT&T. It won't connect to the internet no matter what I try. I've tried all of the suggested APN's, using the phone number as the user/pass, putting the PIN in I had to setup when I started the service with AT&T and followed the guide on this site to set it up the first time. Here is a print of the debug it gives when it boots up and tries to connect.

What am I doing wrong or missing? Any help would be greatly appreciated, I really need to get this thing working.

What plan do you have on the SIM card? Was the modem registered as the device on the plan?

Did you enter these APNs, or was this automatic?
