New GSM G400E Install on CentOS 6.5

I got the card replaced as you suggested and did a clean install of CentOS to clean up anything from the old card. We went with a different GSM Module. I can get it to power on now, but there still seems to be an issue. Not sure why but it doesn't seem to be recognizing the GSM Sim from ATT.

The same Sim card is working in the VS-GW1202 gateway appliance that is also in the same location - so network signal should be fine. I also tried putting a 5db gain antenna on to see if it could find network to no avail.

Here is what I am getting from the CLI>
