Data-only global eSims are super cheap. Having done a lot of international travel lately, this is undoubtedly the best way to go.

Cheaper and better coverage too.

Also, things like iMessage, FaceTime and Signal definitely work with those sims. Not sure about "wifi" calling or SMS with your home country's plan though.

Where would you recommend someone find one of these? Do they expire, or could I get one to cover years worth of travel? Thanks!

I've used the Airalo app to buy data-only eSims in multiple regions, and they have global ones also. I would guess it's not as cheap as you'd get if you waited to buy from local providers in arrival, but it's very convenient.

Eskimo has a 2y global SIM, excluding a handful of countries, https://news.ycombinator.com/item?id=40382377
