As the other comment said it's either airport wifi, prep beforehand, roaming data (if absolutely necessary), or (last resort) you go to a physical phone store usually in an airport and they will set it up for you.

I can download T-Mobile eSIM from Australia - Pay them $15, know what my +1 USA number will be, all before leaving the country. You just can't do this with classical sims.
