Can I enable International Roaming just to receive calls, by disabling Data Usage on Android (and avoid data usage cost)?

I have Android and I see that I can enable International Roaming (Connections >> Mobile Networks >> Data Roaming >> On/Off), and disable Data usage (Connections >> Data Saver >> On/Off). However I´m not sure if this will be useful for what I need, which is BEING ABLE TO RECEIVE CALLS, BUT AVOIDING DATA USAGE since I will be connected to Wifi and I don't want expensive charging for data usage. Is this the way to do it?
