# What can I do if my phone number is unreachable?

Your sipgate phone number is reachable when your **device is online** or **voicemail is activated** . If neither is the case, callers receive the error message **The desired party is currently unavailable.**\\

{% hint style="warning" %}
**Important:** After registering with sipgate, it may take a few minutes until your phone number is reachable. If your phone number is still not reachable, select your device in the Help Center and follow the [configuration guide](https://help.sipgate.de/hc/de/articles/4402636353041-Konfigurationsanleitungen-So-verbinden-Sie-Telefone-mit-Ihrem-Account).
