Outbound messages are not delivering

Modified on Wed, 13 Dec, 2023 at 10:37 AM

If you are experiencing issues with your outbound messages showing as undelivered, there are several possible reasons for this. Here's a guide to help you troubleshoot and resolve any problems with messages not delivering properly:

1.
Unknown or inactive destination number: If you receive an undelivered notification with the error message stating that the destination number is unknown or may no longer exist, it's possible that the number is no longer in service or temporarily deactivated. If you believe the number is active, you can contact LimePhone support at [email protected] to further troubleshoot the issue.

2.
Unavailable destination handset: If the error message indicates that the destination handset is switched off or otherwise unavailable, it means that the message failed to deliver because the contact's device is outside cellular service coverage or turned off. It's also possible that the receiving carrier filtered out LimePhone support and provide specific instances of the problem.

3.
Blocked destination number: If the error message states that the destination number is blocked from receiving the message, it could be due to various reasons, such as the user not accepting SMS from unknown senders, limitations of their mobile plan, or the receiving carrier filtering out the message as spam. If you have ruled out these issues, contact LimePhone support and include specific instances of the problem.

4.
Destination unable to receive the message: If the error message indicates that the destination number is unable to receive the message, it could be because you are trying to reach a landline or an unreachable carrier (in the case of short codes). If you consistently encounter this issue, contact LimePhone support and provide specific instances of the problem.

5.
Unknown error: If you receive an "unknown error" message, it means that the message failed to deliver, and the error notification did not specify the exact issue. It could be due to a temporary outage with LimePhone or a poor internet connection on your end. Check LimePhone's status page for any ongoing issues. If the problem persists, reach out to LimePhone support and provide specific instances of the issue.

6.
Message flagged as violating carrier guidelines: If the error message indicates that your message was filtered or blocked due to violating carrier guidelines, it could be either blocked by LimePhone or flagged as spam by the receiving carrier. If you believe your messages comply with LimePhone's terms of service and you have only contacted us with a brief summary of your business and your usage of LimePhone, along with information on how you collected your contact's information and how they granted permission.

By following these troubleshooting steps and reaching out to LimePhone support when needed, you can resolve issues with undelivered messages and ensure successful message delivery.
