Question Dual sim tray disabled in software (SM-S901U1)?

[dcsam]

Hi all,

I recently purchased a Galaxy S22 (SM-S901U1 - S901U1UEU2AVF7) from Google Fi with the intention of using 2 physical SIM cards and 1 eSIM on it.
On Samsung's website (https://www.samsung.com/global/galaxy/galaxy-s22/specs/) it says some models have "two Nano SIMs and one eSIM".

Upon receiving my S22, I took out the tray and noticed it could only fit one physical SIM card, however, looking at the sim card slot through a stereo microscope it looks like there are SIM card contacts on either side of the slot (meaning the physical connection is there).
Also, doing a `*#06#` shows IMEI1, IMEI2, and EID; which to me signifies the phone itself could support the "two Nano SIMs and one eSIM" option.

I went ahead and bought an S22 replacement SIM card tray with support for 2 SIM cards, and put another SIM card on it but can only see "SIM 1" and "eSIMs" under "SIM card manager".

It honestly looks like Samsung disables the second SIM card in software for the US market.

Can anyone here confirm my suspicion and if so, do you know if there is a way to change that software restriction? Thanks

The second IMEI is specifically for the eSIM, the EID is what one would consider the ICCID if it was a physical SIM.

Only models outside the US have the option of a dual physical SIM.

Thank you for your response.

Do you know if that is a limitation imposed by hardware differences (i.e.: the US version is missing a radio or SIM card slot) or is it imposed by software?
(I have purchased a dual SIM tray to put into my S22)

If it is the latter, would flashing a ROM from a region with support for dual sim cards (and the same processor) enable dual sim cards for the S901U1?

Cheers

I wouldn't know if the hardware doesn't support it.

If I had a guess, it would probably be locked at the baseband with software, similar to the OnePlus 9 Pro. The latter was later confirmed by users; even though the hardware was the exact same across all devices of that model, changing to a different ROM changed nothing as the baseband retained its state.

Also, most if not all non-US models use the in-house Exnyos SOC, so finding a stock ROM to determine this would prove difficult.

Someone might take a poke using QPST and other diag tools. I can't currently do so myself.

looking inside of the sim slot it seems there are 2 sets of contacts has anyone tried to buy a dual sim tray and test? to me it looks like it is a software imposed restriction
