s23 dual sim not working

[Members_mSbMiTe]

Hi,

Last week I bought the galaxy S23 (SM-S911B/DS). It should support the use of two physical sim cards (dual sim)

However when two sim cards are inserted, only SIM 2 is detected( sim slot 1 in the sim manager is grayed out and labeled "no sim card" )

- When I remove the sim card from sim slot 2, then the sim in slot 1 is recognized.

- When I reinsert the sim in slot 2, only this one is detected (sim in slot 1 is greyed out again)

- Swapping the sim cards has no effect on this

- No issues when testing both sim cards individually, or when used in another phone.

As sim slot 1 only fails to detect the sim when sim slot 2 is in use, I believe the sim is correctly inserted, and I think more of a software issue which is preventing me to use the phone in dual sim mode.

- The phone was bought from a legal shop and not imported from another region

- I tried several times to reboot the phone between the tests

- Software has been updated to the latest version

- No activated esim (Nor have I the option to use this feature)

What can I do to test this further? I really want to have two (physical) sim cards in my device.

Thanks in advance,

Best regards,

Thomas

Update: Brought the device to a Samsung repair center. They replaced the complete sim/power module. Issue was solved after that. Duo sim is now possible

You shouldn't have to be troubleshooting so early into owning a phone @Members_mSbMiTe

If the phone is a used phone then ensure there are no eSim files that need deleting in the Sim Manager section. 

If all else fails take the phone back and ask for a replacement. 

May I ask who the merchant is who supplied the phone 🤔

If i can be of any further help please don't hesitate to ask  😎

Hi,

Bought the phone on bol.com. Nothing wrong with the merchant. Its isn't know for selling unreliable products.
And I am certain the phone was not imported from another region or sold as second hand. (package was still sealed)

The reason for all the troubleshooting is I still believe this is caused by a software issue, because both sim slots work individually.

But have tried the reboot/the network settings reset, nothing seems to help. I'll just ask for a replacement.

Thanks.

Kind regards,
Thomas
