Phone models sold in China (even iphones) have had dual sim capabilities for a long time before eSims were a thing. I mean like 2 physical sim card slots in a phone. Adoption of eSims isn’t much of a necessity when the phone itself already can carry 2 sims by default.
On the other hand American phone models only ever had the one sim card slot. It’s a bit strange that eSims haven’t been as widely adopted.
Probably through that weird crypto thing lol, they still have ad revenue with their rewards system.
