Greetings, I am having the same exact problem as every user above my post. Network Manager sees "New GSM conncetion", and it walks me thru the setup for AT&T LaptopConnect (using 'broadband' as the APN). But it never ever connects successfully. I have tried this on Ubuntu 12.04, and now I am even trying it on Ubuntu 13.04. This just does NOT work. I have the Dell 5530 Mobile Broadband card. I have gone thru all the steps for troubleshooting the network card. I am at a loss as to what the next steps are. I have created a *.doc file which contains all the outputs for the different test commands I have run. I will attach it here. Assistance is badly needed here. I am considering rolling out Ubuntu to all of the project managers at my company....roughly 40 laptops. But they ALL have this internal mobile broadband card. Without a fix, I will have to settle on Windows8, and not too happy with that as a solution either.

I've been able to get the card working on a stock Ubuntu Intrepid (2.6.17-7) kernel with a wvdial.conf script. I'd rather be able to use network manager for obvious reasons. I refer to a thread in the ubuntu forums which contains the AT commands to get the modem up and running on. http://ubuntuforums.org/showthread.php?t=979587 Ubuntu Release: Description: Ubuntu 8.10 Release: 8.10 network-manager: Installed: 0.7~~svn20081018t105859-0ubuntu1 Candidate: 0.7~~svn20081018t105859-0ubuntu1 Version table: *** 0.7~~svn20081018t105859-0ubuntu1 0 500 http://gb.archive.ubuntu.com intrepid/main Packages 100 /var/lib/dpkg/status I expect the mobile broadband modem to connect after configuration. It does not connect after configuration - no message explaining why either. Same Issue for IBM Thinkpads which uses the same 3G Card. It would be useful i there is an solution adding AT+CFUN=1 to the init script. Currently there is no way to do so, isn't it?
