Error codes are numeric codes used to signify that something unexpected or unwanted has occurred while sending your SMS.

Think of them like warnings or alerts – they tell you something went wrong, but they also usually point you in the right direction to identify the cause and fix it.


You can find this information in the Connect Portal under SMS > Logs Section.
