just small scenario if data drops, call may switch to network (incurring fees). probably can force sim to connect to unauthorized network so network connection wont happen

scroll down to Learn about Dual SIM status icons

unfortunately with androids, this support isn't clear (which phones have DSDV)

This. I did this back in Jan 2020 with an iPhone XS in India Dual sim Verizon Google FI. Never got dinged for any Verizon usage as my Verizon voice calls were all routed over the data line of FI. iPhone definitely has a leg up on Android with this little-known feature.
