Why have my messages failed to send?

  • Typically messages will fail to send because either the mobile number of the intended recipient(s) is invalid. 
  • The recommended format for mobile numbers is to include the international prefix (dial code) and no non-numerical characters such as brackets:
    • Correct: +61412345678 
    • Incorrect: (0061) 0412 345 678
  • If your numbers are all saved in the correct format, then there is a chance that the number itself is invalid/not in use, or that the sender ID (when sending from a number as opposed to an alpha tag) has been blocked by the recipient.
  • There is also the possibility that the carrier themselves are experiencing issues which could impact your messages being sent successfully.
