I'd also suggest enabling WiFi calling before you leave and enabling "Prefer WiFi While Roaming" which will help minimize roaming costs if you get/make a call while connected to WiFi.
I don't have a Voice Roaming option, only Data Roaming. I'm assuming that turning off Data Roaming, will restrict it to Voice only.
This a T-Mobile phone, and the menus I see are:
Settings>>Cellular>>Cellular Data (on/off)
or
Settings>>Cellular>>Cellular Data Options>>Data Roaming (on/off)
I'm thinking that setting either of those options to OFF might accomplish the same thing.
I already have the use WiFi when available option turned on.
One reason I feel like such a noob is that I have T-Mobile Simple Choice and this is a very rare trip to a country not included in my plan. Haven't worried about data usage in years.
