# Issues forwarding incoming SMS via Flow Builder

If your forwarding flow is not forwarding your SMS (to another phone number, to your email or your webhook URL) please check the below points, before reaching out to us:

* **Step 1:** Check your [SMS overview](https://dashboard.messagebird.com/en-bm/messages/list/inbox) to see if the message was received. If the SMS was not received then there was a problem with sending a message to your virtual mobile number (VMN).
* **Step 2:** Was the message received, but not forwarded? Check your Flow insights to see if message successfully forwarded, if you see success move to Step 3

* If you don't see success in Insights and see an error failed, check which part of the steps failed. Check whether your flow's phone number and forwarding phone number, email address or URL are set up correctly.
* **Step 3:** Check your firewall settings or any other security related setup of your systems and resend.
* **Step 4:** If you followed all above steps and have still not received the forwarded SMS please reach out to our Support team via [this page](https://www.messagebird.com/contact) with the below information:
  * Flow Name
  * Phone number, email address or URL
  * VMN
  * Originating number
  * Since when the forwarding stopped working

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.bird.com/connectivity-platform/troubleshoot-a-flow/issues-forwarding-incoming-sms-via-flow-builder.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
