This is not a problem anymore. I visit about 4+ countries every year (hello IMF / World Bank contracts) and have done 43 countries in last 6 years (on Google Fi, T-mobile and Indian Jio).

T-mobile includes 5GB / month of full speed international roaming in virtually any country in the world. (15 GB for $50 after it).

Getting a new local e-sim does not scale when you visit multiple countries or area in a jurisdiction which requires ton of documentation (including a local address or contact they can verify). Even then, it’s complicated.

For example, just this year I learnt that a local Indian e-sim (pre-paid) will not work in state of Kashmir in India or parts of Xinjiang in China.
