Hello! Is it because the short message was unsuccessful? Try changing the SIM card. It may be caused by the arrears of SIM card. If you still can't send it, please try to restore the phone to the factory settings. Just go to Settings-More Settings-Restore Factory Settings-Restore all settings, and restore all settings without losing the data in your phone.
