There are plenty of options available, just google (or alibaba) for
"GSM module". Most comes with RS232/TTL or serial emulation on USB.
Another option we used was to use SE mobile phone with AT commands.
Interface is well documented here for almost all SE phones:


I am not aware of application. IMO, while GSM modem based approach may
work for low volume services, it may turn out to be disappointing for
high volume application. We tried GSM modem approach for an application
and later moved to service provider based option which proved to be
more reliable so far and interface was much easier as we used third
party servers (we could not physically connect GSM modem to the third
party servers).
