Do you think the trend is to put eSim plus regular sim on some of lower and mid range phones ?

I don't think it's a plus for the Carriers to push dual sims as it's taking $$$$$ out of their pockets.

And most phones do not have the LTE bands for overseas even if you do get them unlocked,

I am doing a Moto e5 play up for overseas use as it has a lot of LTE bands , but it sure would be nice to also have a eSim to put something like Google Fi along with a local sim.
