This is probably a stupid question but I've never used an eSIM before so want to make sure I don't accidentally get roaming charges on my usual SIM.

I have a trip planned to the Netherlands and Germany next month, 7 days. I plan on getting data only eSIMs for my wife and I. I'm not entirely sure what carrier I'm going to use yet and would love suggestions if people have them, but my question is - we currently have physical Verizon SIMs in unlocked iphones. When we activate the eSIMs do we need to take out the physical Verizon SIMs like we would if we were swapping physical SIM cards? I ask because I plan on buying a data only eSIM so I don't want to get roaming charges if I happen to get any texts during the trip (I wouldn't actually respond to texts or answer any non emergency phone calls).
