Java – Why can’t I send creepy skeleton text messages?

I’m making an app to send this string :

    ░░░░░░░░░░░░▄▐
    ░░░░░░▄▄▄░░▄██▄
    ░░░░░▐▀█▀▌░░░░▀█▄
    ░░░░░▐█▄█▌░░░░░░▀█▄
    ░░░░░░▀▄▀░░░▄▄▄▄▄▀▀
    ░░░░▄▄▄██▀▀▀▀
    ░░░█▀▄▄▄█░▀▀
    ░░░▌░▄▄▄▐▌▀▀▀
    ▄░▐░░░▄▄░█░▀▀
    ▀█▌░░░▄░▀█▀░▀
    ░░░░░░░▄▄▐▌▄▄
    ░░░░░░░▀███▀█░▄
    ░░░░░░▐▌▀▄▀▄▀▐▄
    ░░░░░░▐▀░░░░░░▐▌
    ░░░░░░█░░░░░░░░█
    ░░░░░▐▌░░░░░░░░░█
    ░░░░░█░░░░░░░░░░▐▌

This method sends text:

protected void sendSMSMessage(String phoneNo, String msg){
    try {
        SmsManager smsManager = SmsManager.getDefault();
        smsManager.sendTextMessage(phoneNo,null,msg,null,null);
        Toast.makeText(
                getApplicationContext(),
                "SMS sent",
                Toast.LENGTH_LONG
        ).show();
        Log.v("sendSMSMessage",msg);
    } catch (Exception e) {
        Toast.makeText(
                getApplicationContext(),
                "Failed to send. Try again.",
                Toast.LENGTH_LONG
        ).show();
        e.printStackTrace();
    }
}

If msg is “test” and I run sendSMSMessage, a few minutes later I get the string “test” on my phone. If msg is a ghostly framework, the method runs, but I don’t get the text, and the console doesn’t show any error – pops up an “SMS sent” toast to show that the code executed correctly.

I

received text when I manually texted myself to a ghostly skeleton, but it was all over the place with “(X/6)” (where “x” is a number, of course).

Can’t I send skeleton text messages?

If so, should I make it into a picture and have the code send it as an MMS?

Maybe the message was too long and it quietly failed somewhere, using divideMessage and sendMultipartTextMessage:

ArrayList<String> parts = smsManager.divideMessage(msg);
smsManager.sendMultipartTextMessage(phoneNo, null, parts, null, null);
