I don't think the data-only eSIM will effect things -- whatever your main carrier did before, they probably will do with a secondary data only eSIM. For T-Mobile, if I let a call go to voice mail (that is, I don't answer) and they leave a message, I get charged for a 1 minute call (25 cents). These always come during my "Do Not Disturb" hours so I don't have a chance to reject them. Robo calls that hang up when connected to my voice mail don't seem to cause a charge.
