Travel eSIM Plans Shift From Pay-Per-Gigabyte to All-You-Can-Use

Travel eSIM services—digital phone plans you install on compatible phones—are moving toward simple, unlimited data pricing instead of charging per gigabyte. Saily's May launch and competitors like Holafly are leading this shift. It mirrors how US home phone plans moved to unlimited decades ago. One catch: carriers haven't disclosed how fast your speeds actually slow once you've used a lot of data.
