What does the MSG-023 Error mean?
If a message you sent is not delivered to the end device and returns a MSG-023 error code, this means that your message marked as spam and rejected by a downstream carrier (AT&T, Verizon, T-Mobile, etc).
Troubleshooting
Wait until after the daily carrier reset (11:59PM PST) to attempt the message again to a few contacts.
If you are sending links, try sending a message out a link to the same contacts.
Contact our support team to open an investigation with the carriers.
Possible Causes of MSG-023
- Your message was identified as spam or unwanted messaging
- Your message was flagged as objectionable and blocked by a wireless carrier
