I'm using it with 2 sim cards. In my old Honor 9, the call would be placed through the same SIM used the previous time. It was pretty handy when connected to my car. Now, if I try to place a call while driving, I have always to pick the SIM in the phone. This is for phone numbers not saved in my contact list and for which I have not selected a preferred SIM.
Is there a way to have the S21 default to the SIM used last time?
