when person send SMS, the user can't change the sender number (Name or number that appears).
YOU CHANGE in the system the sender that appears in people who receive the SMS. This is the number that appears or the name.
I want to person change and replace the SMS sender when they send SMS.
You create an APK for change the sender (Name or number that appears) in the system, enable or disable this option. There is only 1 box for put the new sender.
