As a frequent traveler I can’t imagine going back to physical SIMs, now I can carry all my data plans on my phone and don’t have to waste time looking for a place to buy a prepaid plan.

There are a ton of websites where you can immediately get esims for almost every country, why bother with physical sims?

In some places the e-sim plans are inflated and poorer value compared to the deals on physical sim cards sold. For example the unlimited data plans might be only available by sim rather than purchasing data packs

They’re rarely poorer value if your time is worth anything, if getting a prepaid SIM costs me a 30min detour I might as well be setting $100 on fire.

Thanks. I never knew, plus I haven't troubled in 2 years :). What is a good recommendation?

Airalo is the one I find myself using the most, amazing coverage and great support.

I’ve probably used their sims in 30+ countries at this point, they’re even available in more exotic places like St Barthelemy or Moldova.

They’ll iron it out pretty quickly if iPhones can’t use their network.

As a traveler you can have 10 or more eSIM profiles. That means you can have a great 130 multi-country eSIM like the AIS eSIM2Fly or if you go to a single country you could get their local travel eSIM ( for example the Thailand DTAC Tourist eSIM ). Just switch between your active eSIM as needed. iPhones have more than enough eSIM slots to accommodate your travels, with no more need for plastic chip fiddling.
