SmsManager NullPointer Exception. Confused... so simple, should work

If I send the following.

SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage("2064035760", null, "Message", null, null);

It throws the following exception.

I have the proper permissions.

java.lang.NullPointerException

See this question. Have you tried using sendMultipartTextMessage? It seems that if the message is too long it will throw a NullPointerException (why I don't know). I realize your message only says "Message", but it is worth a try.
