Hi Marc, if you mean GSM/UMTS SMS when sent from a phone (MO, mobile originated), the answer is no. There is not even a field for the sender number in MO SMS, as it gets inserted by the SMSC. If you send SMS via an SMS provider who has a direct link to some operators SMSC, you can set the sender field to any value, including an empty field. As for silent SMS, they can be sent from most phones / UMTS sticks with AT commands by setting the TP-PID value to 64. Some operators however reset that value to 0 so the message arrives as a normal SMS at its destination - you have to try in advance. For the actual coding of the TP-PDU take a look at 3GPP 23.040 and for the AT commands for sending SMS 3GPP 27.005. -Tobias On 28.12.2011 21:16, MArc Richter wrote:
