I am planning on buying data via an airalo esim. On this page: How To Make a Phone Call With a Data-Only eSIM it says:
The easiest way to make a phone call with a data-only eSIM is with an
internet-based calling app like Whatsapp ...
The only catch is that the person you're trying to reach must also
have the calling app downloaded.
I'm ok with that for calling friends/family, but what about if we need to call any places in Italy (our apartment or some service)? Any thoughts?
