Connecting to Internet, apps are not displayed

Good day, I got an XC40 T3 first registration 03/2022. The car is a reimport from Sweden where the navigation software was deleted. Now I tried to install Google Maps, which was not possible. An Internet connection is established (now via SIM) and it is also possible to use already installed apps (Spotify) and to create updates, but new apps are not displayed and not found. I have now also Volvo Deutschland k Ontact, but they could not help me either. Now I ask you, do you know the solution? Thank you in advance for your help & warm greetings Jörg
