how to call user mobile other application from inside my qml application.

cc ArcGIS AppStudio does AppFramework have any helpers for this?
This can easily be done by calling Qt.openUrlExternally(target). Qt QML Type | Qt QML 5.15.0 . You need to know the URL Scheme or App link for the target application.
For example to open Survey123 field app, based on this doc, Integrate with other apps—ArcGIS Survey123 | Documentation
If you are going to use URL Scheme to open another app from your custom AppStudio app, you need to specify the target URL Scheme in the setting of your app, in AppStudio Desktop. Settings->Advanced->Launch URL Schemes
