Hello, what Wavecom series do you use? The communication between apps and your wavecom would be using [login to view URL] library, so we could use the current SerialPort control. You could use following command for USSD commnad; AT+CUSD and for SMS: AT+CMGS That's all easy. huh? Let me know if you OK with my price
