Help S21 plus no data during calls

I've read about this a few times on AF, and it's apparently when a carrier netowrk doesn't support VoLTE with certain phones, and so it's using a 3G CDMA network for the calls. CDMA/EV-DO doesn't allow simultaneous calls and data AFAIK.

Are you in the US and is your carrier Verizon, or something?
And what exact variant of the S21 have you got there. Was it imported, as you said you have two SIMs in your phone? AFAIK dual-SIM phones aren't usually sold in the US
