(With just WiFi calling too, you may not have a data connection for whatever reason.)
So when a call comes in on the ‘home’ line, some people will just pick up…
Trust me, I’ve seen my dad rack up $30 calls of <10mins more than a few times; his roaming fees in a few months have been higher than than the base plan itself. The mobile provider knows what they are doing…
Your dad was scammed in his home country by the quick call hang up which he returned to incur the charges. That’s an old scam which is blocked on my plan.
When traveling internationally, my domestic esim uses the data of the local esim for WiFi calling. Absolutely no reason to remove/disable my sim with this setup. My son has been deployed to Europe and hasn’t incurred any international charges while traveling in Germany, Latvia, Poland and the Rep of Georgia.
