    Are you aware of you need a Licence from your local authorities before you are going to use a GSM frequency? Be carefull every country take it very serious when you are trying to use air medium for transmission. If you are planning to go for GSM modem what i recommend you to use the telcome operator sim with EDGE, GPRS, or 3G technologies for data transmission and use standard phone as a transmitter/receiver. Correct me if i am wrong
