Per our carriers' requirements, these SIDs can be no older than 48 hours at most.The SignalWire Compatibility REST API is a comprehensive REST API that enables easy management of all aspects of the SignalWire Compatibility functionality including calls, conferences, messaging and account maintenance. Please open a support request and include a minimum of 3 or more message SIDs where a 30008 error was thrown.

Try rebooting the device or contact the mobile carrier for help. If messages to other phones go through, the issue is likely device related. Try sending to other phones who have the same mobile carrier (you can use our Lookups API to determine the carrier if you’re unsure).We cannot guarantee message delivery on roaming phones. Ensure that the phone is not roaming off network.

Check that the phone you were sending to is turned on and can receive non-Twilio SMS.When Twilio receives a very generic error from our carrier partner that we have no further details about, we associate the message with the error code 30008, letting you know that Twilio truly doesn’t know what caused this error from the provider. If a message you sent is not delivered to the end device and returns a 30008 error code, this means that delivery of your message failed for unknown reasons.
