If you had an IPhone, you need to disable the Imessages account in Apple. Also, you can contact your carrier to get help. Generally, you need to go to Settings, Software Update and click 1 Update Profile, 2 Update PRL and then you Restart. This is a SMS server issue from your carrier and not really Samsung. Apple Imessages are not SMS but a web service hence they don't depend from the carrier.
