Sprint EVDO Mobile Broadband on Ubuntu

So I just got a Sprint EVDO USB stick to allow connectivity when there's no WiFi around. I did some quick Google searches and it looks like it's supported. Little did I know how well :) I plugged in the device to a USB port and the kernel started loading appropriate modules and gave me the /dev/ttyUSB0 through /dev/ttyUSB3 ports. At this point I thought I'd pick it up at home.

I couldn't resist one last Google search, however, and it was worth it :) While the box for the device (a Sierra Wireless 598U) doesn't mention Linux by name, Sprint provides a full installation guide for Ubuntu (Fedora and others are there too). I was very pleasantly surprised. Everything just works!


  1. I wish I had your luck! I am having the most difficult time with this. Mine is not able to recognize the 598u. It didn't start loading the modules and I cannot install KPPP. I keep getting an error message. When I check for the settings, it shows I have the correct product ID and vendor ID and lists that it is Sierra Wireless, but I am not getting any further. I thought that Ubuntu already had the usb serial drivers on the OS or do they have to be loaded from the CD first? Thanks, Brandi

  2. Brandi,

    The drivers should already be available as modules. I'll try this again on Linux tomorrow and see if I can document this further.
