# Troubleshoot SMS Short Code Issues

> If you are not receiving Beacon SMS alerts, a carrier-level or device-level block on the Beacon short code is the most common cause.

GoGuardian Beacon sends SMS alerts from the following short code:

**38121**

If you are not receiving Beacon text message alerts, the short code may be blocked at the device level or by your phone carrier.

## Review Common Causes and Fixes

<AccordionGroup>
  <Accordion title="Short code blocked in device settings">
    Some smartphones include a setting to block premium or short code messages. On certain devices — such as Samsung Galaxy phones — this setting may be labeled **Enable/Disable Premium Messaging** or similar.

    Go to your phone's messaging settings and confirm that short code messages are allowed.

    <Note>
      This setting is sometimes enabled by the sales representative at the store where the device was purchased, without the user's knowledge.
    </Note>
  </Accordion>

  <Accordion title="Short code blocked by your phone carrier">
    Your phone carrier may be blocking short code messages at the network level. If your device settings are already configured to allow short codes, contact your carrier to:

    * Request that short codes be allowed on your account.
    * Ask them to whitelist short code **38121** specifically.
