Dual SIM management on the iPhone is not very efficient. I am using an iPhone 13, and I have to frequently change the SIM line because sometimes I recharge one SIM, and other times I recharge the second SIM. I have selected the default SIM line in the settings, which means calls should always go through the default set SIM line. However, this is not happening. I have to manually go to the contact of the person and change the SIM line before making a call. Could you provide a feature where, when calling any person, the call always goes through the selected default SIM line?
