I occasionally get request for commercial support for Gammu, but I'm not willing to do this for years. In case you are a developer who is wiling to offer commercial support for Gammu, please leave your contacts here, so that users can find you.

There is also option to use https://www.bountysource.com/teams/gammu for funding some development, but I'm afraid this platform is not the best choice and it might be deceased soon (it is having a lot of technical issues recently).

Maybe @kstuart or @melones would like to be listed here.
