SMS Error Codes

While sending messages, CallHub system sends the message to the telecom carrier and the carrier notify CallHub if the messages were successfully sent, delivered or failed. Telecom carriers use error codes to identify the reason of the message failure, which can be viewed under “Error Code” column in the SMS Report. Error codes are described in the table below:
