Try to use something like this. Not tested, but should work fine. Drop a note when you see some problem here.

This is just to show how permission granting in Android M works. Please extend it by functionalities mentioned on Android tutorial site about permissions.

You will need add ActivityCompat.shouldShowRequestPermissionRationale check to match best practices. I can extend this answer but I think it's not necessary. Just make sure you are granting permissions in runtime (or use targetSdkVersion lower then 23 - this is however not recommended)

private static final int PERMISSION_SEND_SMS = 123;

private void requestSmsPermission() {

    // check permission is given
    if (ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) {
        // request permission (see result in onRequestPermissionsResult() method)
        ActivityCompat.requestPermissions(thisActivity,
            new String[]{Manifest.permission.SEND_SMS},
            PERMISSION_SEND_SMS);
    } else {
        // permission already granted run sms send
        sendSms(phone, message);
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_READ_CONTACTS: {

            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // permission was granted
                sendSms(phone, message);
            } else {
                // permission denied
            }
            return;
        }
    }
}

private void sendSms(String phoneNumber, String message){
    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, null, null);
}
