Most modern smartphones, tablets, and smartwatches support eSIM technology. Popular devices include the latest models from Apple (iPhone XS and later), Google (Pixel 3 and later), and Samsung (Galaxy S20 and later). Always check your device specifications to confirm eSIM compatibility.
When in the TIA Kathmandu in Nepal upon it didn't work, sought assistance next day and switched to LTE instead of 5G which stopped to activate. Upon departure, even with LTE it didn't work at the airport. That's where you needed most as airport WiFi was also on and off and yesterday when I was in the plane forced to wait for 1hour 30 minutes I wished your eSIIM worked.
