On your mobile phone, this varies between phones, but the following is a general outline:
Enter your message
! D
and send it to Phone No. 14163992003
Your mobile phone or the phone you established as originating number will receive the call from SMS Call, as it is the default FROM number in this case. For future calls, merely recall a previous message from your “Outbox” and send this, rather than re-entering the above information. Also if your terminal allows it, you can put your messages as a template and 14163992003 in the memory of the terminal.
Or
! D OFFICE (OFFICE is in your FROM directory, but was not specified as the default FROM number, and will receive the call from SMS Call)
and send it to Phone No. 14163992003
In this example, SMS Call will call you back at the FROM number you have chosen.
You
will then be prompted by a voice message, to enter the TO number followed by
the # key. Stay on the line and your TO number will be dialed and connected.
