From Android 4.4, You can't do any kind of operation on SMS except just reading it if your app isn't the default SMS app.

If your app is default sms app and you want to block sender or whatever then put your SmsReceiver in Android Project and register it in Application class.

I don't think you need to do anything in Forms Project.
