Currently, to use a non-default SIM for a call, I need to dial the number first and then manually switch the SIM. It would be much more user-friendly if there were an option to select the SIM (SIM 1 or SIM 2) before initiating the call—either via a popup or a long press on the call button. This would save time and improve usability for dual-Sim. This was possible in one of the older versions.
