Any Samsung phone with the Qualcomm X75 modem supports DSDA. On my USA Unlocked Galaxy S24 I have two eSIMS, a Visible one and a T-Mobile one. Recently I had my Visible eSIM set as my primary. Somebody called me on my T-Mobile number and the Galaxy S24 phone automatically switched to my T-Mobile eSIM so I could answer that phone call. After I ended the call the phone automatically switched back to my Visible eSIM.
Thank you. I believe this is more of a standby feature since both Sims can't be active at the same time for data. I have tested both Sims and while I am on a call with either of them, I can't receive calls or text on the other one until the call ends. This feature would make a world of a difference for my work and personal numbers.
