The problem I had with products like Airalo is that if you are traveling and need to actually call a hotel, excursion, or any company in the country you are visiting you cannot do that with just a data eSIM like Airalo.

Sure you could use WiFi calling maybe but in my experience when I really needed to call someone I had to switch back to my original carrier and incur the $10/day fee.

I just have a carrier that gives me free international data and calling, regardless of the level of plan.

Most Canadian carriers do a "use your plan like you would at home" but the price for it is about USD 10 per day, which is a huge cost compared to many travel eSIMs or a local SIM/eSiM.

Is this just a switch to eSIM from regular SIM? Travel sim cards have been a thing for at least two decades.

Unless you live and travel within the EU. Then you can use your phone as much as you want and know that you won't get a higher bill than usual.
