Gammu is a named product that is not among the candidates, so no source confirms it; the candidates below only address the general task of sending SMS. Closest matches are simhook, which sends SMS from an Android phone's own SIM, and Twilio and Seven for programmatic SMS over a cloud gateway 1029.
A question back: Did you mean Gammu, the open-source tool for controlling GSM modems and phones over serial, and which device or SIM setup do you plan to use?
