I had recently got MTS 3GPLUS dongle. It is made ZTE and really good news about it is that it supports Linux and it is mentioned in their website (you can view the supported os list in "tech spec"). I have tried it in Windows 8, OSX Mavericks and Ubuntu 13.04 and it works really well on all these platforms.
In mac and windows, it will auto configure everything for you. But in Linux, you need to install it manually. When I plugged it into my ubuntu, it was detected as USB drive but there was no auto configure for it. Even I was not able to load the installation files in Ubuntu. Then I have to plug it into another Windows and was able to see it includes the files for installing it in Linux too.
