Example GSM Modems

You can use these or other GSM modems with the SMS Server Tools.

Falcom A2D-1

Size: 115x54x33 mm
Power: 11-32V, 0.5A
Data: 300-14400 bps, V21,V22,V32,V110
Antenna connector: FME female

Connect a stabilized 12V 500mA power supply using the plugable cable that comes with this modem. You need to add a power supply, a 9 pin serial cable and a GSM Antenna with male plug.

You can save a little bit money by using a self-made antenna. Buy a silver coated wire 34cm length and 1.3mm thick. Plug that into the antenna connector. This antenna worked fine for all my customers.
