[tcstudio]

I have developed an app to allow user of the computer system with in my company to send text messages. As the only people to send and to recieve text messages are company employees I wish to with hold the mobile number they are sent from. Does any one not if there is any AT commands to do this.
I am using a Nokia 22 to send my message from a vb app using at commands.

Hi!

There is no way to leave the MSISDN number out, when sending SMS messages using ANY mobile device.

Only way to have this functionality is to use some direct connection to operator SMSC.
