A really great tool !! I'm using it with different UMTS UBS stick since years because there's no compareable successfully working built-in tool in Debian derivates until now. (Currently I've problems to run UMTSmon under Kubuntu 11.10 but I'm sure my little problem can also be solved within a very short time frame.) UMTSmon should be updated and considered by the several Linux distributors as a standard part of the distribution !
