Error 30004

Message Delivery - Message blocked

Possible Causes

• The destination number you are trying to reach is blocked from receiving this message (e.g., due to blacklisting).
• 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.

Possible Solutions

The first step to troubleshooting this issue is to attempt to replicate the problem.

If you see similar results, continue troubleshooting with the following checklist: Is the destination device powered on? Does the device have sufficient signal? If not, power the device off, then wait 30 seconds and then power it back up. Is the device connected to the home carrier's network? We cannot guarantee message delivery to devices roaming off-network. Can the device receive non-TextP2P SMS? Can the device receive messages from another TextP2P number, or with a shorter one-segment (non-concatenated) body? Can other devices using the same mobile carrier receive your messages?

If you can rule out all of the above issues, continue troubleshooting below.

"Failed" messages

Repeated messages with a Failed status and error 30004 results indicate TextP2P may be filtering some of your messages internally.

This filtering is in place to help protect our customers, and the rules attempt to match what we have observed from the industry. For more details, including potential workarounds, please see our help center article "How Does Carrier Filtering Work?"
