We need to make sending SMS on call rejection optional. Someone may want to use it, other may not. Because users live in different countries, speak different languages we need to make SMS text editable.

Settings will be the right place for it. There have to be a text field where user can write a message. If the message text is empty (default), than we dont send SMS. If user adds visible text, on edit we ask for SEND_SMS permission and save text to preferences. Because user have to enable it manually we dont need to show alert dialog.

Dont forget that calls may be not from local mobile numbers.

Oke sorry for the misunderstanding I will change it to settings to make the sms message optional.
