Hi, That message is not going to change the SMSC address on the phone, even if the phone did understand it. That is an old format Nokia/SonyEricsson OTA message, which is not supported by many current generation handsets from those manufacturers, as they have switched to using OMA OTA provisioning. However, these settings would not change the SMSC address in even an older phone. This would ... if a phone supported it ... configure the WAP browser in the mobile phone to browse over SMS. In the early days of WAP, they thought that maybe small web/WAP pages could be retrieved over SMS. Needless to say, that was an impractical idea, and I doubt that there were any mobile phones that were sold commercially which had this capability. The bottom line is that if you are trying to change the SMSC address in the mobile, this is not going to work. And you can't do it via OMA OTA either. The SMSC address is stored as a file on the SIM card. You need to send SIM card provisioning messages to change this. That requires knowing the secret code for the SIM. ETSI GSM 11.11 defines the commands for updating files on the SIM card. ETSI GSM 03.48 defines the security mechanisms and encryption that is applied to these commands. Unless you have access to the SIM card security codes, you're not going to get very far. -bn |
