 eSim1 & physical sim1 both are not running same time, eSim 2 & physical sim 2 also not running same time.(S25 Ultra )

What is the reason

In my iPhone any 2 Sim can run 

[Shahzaib-Ali-hai]

Did you try esim 1 and physical sim 2?

[MSBhutta]

Opposite sim working

[Shahzaib-Ali-hai]

Then what is the issue? You can use both sim right?

[MSBhutta]

Esim1 & physical sim 1
Esim2 & physical sim2
Same time not working only opposite sim working

[Shahzaib-Ali-hai]

You can have 2 working sim at a time if have a dual sim one.

[Shahzaib-Ali-hai]

Even have a 2 dual sim and 1 e sim you could one use both dual or 1 e and 1 physical.

Thank you for your inquiry.

We understand your concern regarding using eSIM and physical SIM combinations on your Galaxy S25 Ultra.

Kindly note that Samsung devices support Dual SIM Dual Standby (DSDS), which allows two active lines at the same time, but with certain hardware limitations. On your device, you can use:
1 eSIM + 1 physical SIM, or
2 eSIMs (if supported)

However, specific combinations like eSIM 1 + physical SIM 1 or eSIM 2 + physical SIM 2 may not work simultaneously due to how the SIM slots and eSIM profiles are internally mapped on the device.

This is why the “opposite” combinations (eSIM + the other physical SIM slot) are working correctly.

This behavior is normal and related to device design, unlike some other devices which may handle SIM combinations differently.
