Prepaids travel Esim

I’ll be travelling to the USA in a few weeks and was thinking about buying a prepaid esim.
When looking at sites like this one Travelsim eSIM- International eSIM for 200+ destinations it seems that they are limiting the esim to certain brands/models of phones such as iphones, Samsung, etc …
This shouldn’t matter for the FP4 no? Esim is an esim, or are these made specific for the models mentionned above?
Thanks for your advice!
