If it is the same as the S23Ultra, please note the following:

- Simultaneously 1x physical SIM plus 1 x E-SIM at the same time: Works
- Simultaneously 2 x physical SIM: Works
- Simultaneously 2 x E-SIM: Unfortunately this does not work

Correction from 03/02/2024: The S24 Ultra can also use 2 x E-SIM at the same time (the S23 Ultra could not). I entered it briefly and it works perfectly.

Hi, I haven't tested this yet on the S24 Ultra, but you can choose the internet connection on one of the 2 sims... I don't understand why this is useful, but if you ever register 2 Whatsapps with 2 different numbers, there's no need to connect 2 sims to the internet, just 1 will suffice for the internet.
