# Use the sipgate app in the mobile browser

The sipgate app can also be used in a mobile browser — e.g. on a smartphone or tablet. Depending on the operating system and browser, there are differences, especially in the behavior of incoming calls (ringing, notifications) and microphone usage.

{% tabs %}
{% tab title="iOS" %}
The app basically works in Safari, Chrome, and Firefox. For use in **Safari** additional settings are required so that incoming calls ring and the microphone can be used continuously.

**Allow microphone permanently (Safari)**

1. Open the app in Safari:
2. Tap on the left in the address bar on **aA** or the website icon
3. Select **Website settings**
4. Set the microphone to **Allow**

**Let incoming calls ring (Safari)**

Open the **iOS settings** and click there on **Safari.**

{% hint style="info" %}
Note: This setting is required so that Safari emits a ringing signal for incoming calls.
{% endhint %}

**Chrome on iOS**

The app can be opened via Chrome on iOS. However, incoming calls are **not signaled audibly**, because iOS does not allow continuous audio playback in the background in these browsers.

**Firefox on iOS**

The app works without restrictions.\
Incoming calls ring automatically — no additional settings required.
{% endtab %}

{% tab title="Android" %}
The app works without restrictions.\
Incoming calls ring automatically — no additional settings required.\
This applies both to use in the browser and as an installed PWA (Progressive Web App).
{% endtab %}
{% endtabs %}
