ERROR - 30003: Unreachable destination handset

The destination handset you are trying to reach is switched off or otherwise unavailable.

Possible Causes

  • The destination handset you are trying to reach is switched off or otherwise unavailable.
  • The device you are trying to reach does not have sufficient signal
  • The device cannot receive SMS (for example, the phone number belongs to a landline)
  • There is an issue with the mobile carrier

ERROR - 30006: Landline or unreachable carrier

The destination number is unable to receive this message. Potential reasons could include trying to reach a landline or an unreachable carrier. 

 

ERROR - 30007: Message filtered

Your message content was flagged as going against carrier guidelines. Your message was filtered (blocked) by Twilio or by the carrier.  Examples of messaging that would be blocked by Twilio are spam, phishing, and fraud. Twilio’s filtering system is in place to protect mobile subscribers from spam or other forms of malicious or unwanted messages. Wireless carriers have filtering systems in place as well. These carrier filters are used to block abusive traffic, as well as to enforce rules or regulations about what types of messaging are allowed to that country or mobile network.

 

Error - 30008: Message Delivery - Unknown error

If a message you sent is not delivered to the end device and returns a 30008 error code, this means that the delivery of your message failed for unknown reasons.
