In older days GSM engines ( gsm modems ) will have serial interface and can be controlled by programs using AT command. We can process sms, call numbers and other such operations. Likewise, is it possible to control the 3g data cards ( which takes a 3g enabled sim card inside it ) through programming from pc? is there any standard for interacting with 3g datacards like AT commands? Thank you.
