You will also need to aquire a GSM Modem. SMSGate development and testing was done with this make/model of modem "Wavecom WMOD2B GSM Modem". We do not gaurantee it will work with any other brand of modem!. Most GSM modems cost around US$500 to US$600 though that is a rough estimate as with anything depending on make, model and features you can pay just about anything.
