SMS Errors


There are different reasons that a text message will result in an error. CivicReady will identify unreachable numbers such as landlines or others that are not connected to the SMS Enterprise Ecosystem (such as OTT numbers), and blacklist them from receiving communication through SMS message. 

  • Please note that this may also apply to some numbers outside of the US, including Canadian numbers.


Important Note

  • Phones using a WiFi service should still receive text (SMS) messages.
