If you're visiting the United States and wondering whether to buy a physical SIM card at the airport or get an eSIM before you leave home, the answer is almost always the eSIM. It's faster, cheaper, and doesn't require navigating a US phone store on the day you arrive jetlagged from a transatlantic flight.
We returned to the US regularly during our years of full-time travel, and we've run this comparison multiple times. Here's what we've found.
