# How do I manage my mobile data?

Under the menu item **Mobile network** all data related to the **mobile data usage** is displayed:

* Overview of your mobile devices (smartphone, tablet, smartwatch, etc.)
* Remaining data volume
* Data usage in real time

This menu item is also the central place for managing your data volume: here you can flexibly book additional data volume, cancel it, and switch to a higher volume at any time.

#### **How do I add a new mobile device?**

In just a few clicks, you can under **Mobile network** equip new mobile devices such as smartphones, tablets or smartwatches with an eSIM profile or a conventional SIM card. The booked data volume is shared by all devices after the SIM is activated. Click the top right on **Add device** and follow the steps.

#### **As an administrator, can I manage users' mobile data?**

Yes. Switch to the corresponding user at the top left and book under **Mobile network** data volume or add devices.

#### **Can the data volume be used by all mobile devices in parallel?**

It is possible to use the data volume on all user devices. The data volume on the user devices with the main SIM and the MultiSIM can be used as needed. This makes it possible to connect several mobile user devices to the Internet at the same time. Booked data volume is shared by all mobile user devices.

#### **Can all mobile devices make calls?**

Provided the device technically has a telephony function (except Apple Watch), it can also be used for calling with any active sipgate SIM.

#### **Can mobile devices also make calls in parallel?**

No, that is not possible. Mobile user devices cannot conduct parallel calls.

#### **Is a voice flat rate valid for all mobile devices?**

If users have booked a voice flat rate for mobile service, it covers calls from all mobile devices.

#### **What happens when my data volume is used up?**

If you use up your data volume early during the current billing period, we will reduce the data rate to 64 kbit/s for the remainder of the billing period.

## 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://help.sipgate.de/cloud-telefonanlage/en/using-sipgate/mobilfunk/wie-verwalte-ich-meine-mobilen-daten.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.
