but it is most likely not as easy as an app on your smartphone You mean an app like Google Voice, or one of the many other SIP/VOIP apps out there? I use Localphone as my home SIP provider, and they have an app: https://apps.apple.com/us/app/localphone-international-calls/id1328874519 https://apps.apple.com/us/app/localphone-international-calls... There are tons of ways to make cheap calls from your phone -- when I used to travel internationally a lot, I set up my Android phone dialer with my SIP provider, then I could make and receive calls from the default phone dialer. But now I don't even bother, I just call home via a video call using Hangouts/Meet or Zoom and use my local SIM to make a local call.
