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.
Hello TS! Do you have an update here?

I'm going to be traveling internationally in a few months, and more than likely going to end up on a local SIM where I'm going for while I'm there.
On the single SIM tray there appears to just be a spacer molded into the tray where a second sim would go in the dual sim version. I'm thinking about ordering a dual SIM tray from China on eBay (10 bucks) so I can use the second sim slot in the tray as storage for my not in use sim.
Anyone know of any reason this shouldn't work? I can't think of any reason it shouldn't...

You'll have to flash a dual sim firmware package but there's issues with flashing firmware that's not what originally was installed on your moto z play.
You could ultimately loose your IMEI , Which would render your phone useless.
It's just easier to sim unlock and insert a single sim.

I'm already sim unlocked (have the US unlocked version courtesy of republic). My intention is to only use whichever sim is in slot 1. I'll manually pull the tray and switch sim positions when I need to switch. I just want the second slot as dead storage space for the unused sim card. Just wondering if there's something physical in the guts of the single SIM version that could be damaged by or cause damage to the unused sim in slot 2 of the tray. Or if there's something physically different about the dual SIM tray that will not allow it to fit in the single SIM version of the device.
Definitely no flashing of dual SIM firmware happening on this device.
You should be fine. Just make sure that the active sim goes in the same slot as where it would go in the single-sim tray and the inactive sim go in the spare slot. It's a good way to not lose a sim card. I was thinking of doing this for my single-sim, carrier variant Moto x play, but never bothererd.

Thanks. Avoiding losing a sim while on my trip is my primary reason for doing this. Guess I'll give it a shot!
Update:
Received dual Sim tray from China today (13 days order to door, $10 shipped on eBay)
Visually compared both, they seem basically identical, with the exception of some type of serial number sticker on the original single Sim tray.
Fit isn't quite perfect - the angle of the outer piece of the tray isn't quite right, so it's a tiny bit recessed into the edge of the phone on one end, and slightly raised on the other end. Enough to be visually noticed if you're looking for it, and can be felt running a finger nail over the seam between the edge of the phone and the Sim tray. Don't believe it's enough to present any "catch" issues if running naked, and a total non issue if using a case or bumper.
No apparent functional issues - device connects fine using Sim 1 slot in tray. Did not feel any unusual resistance when inserting tray with both Sims aboard. Obviously doesn't see the Sim in slot 2.
Nice to be able to carry both my Sims with me, worry free. Worth the money for my use case.
Hi everybody, i have a Tab S4 SM-T830, and i saw that this tablet have a sim card reader even there is a space for a sim card on the tray for micro sd card, is there a way to make work that sim card reader? Because it is a wifi model tablet but the hardware is there.

i doubt it very much the hardware is there. As some user have flashed WETA rom, the phone dialer shows up on the SM-T830 WiFi model! You could try flashing WETA and then try a sim card!

I'm realy not sure if all necessesary hardware are there but at least the sim reader and the sim space in the tray yes. I will try later with weta rom. Thx
I think the WiFi Model has the space for the bigger tray that includes the Sim. They don't want to redesign the tablet because of the little space they could be used. Maybe is the Sim reader is there too.
But I don't think that the WiFi model is capable of LTE or 3G. Samsung probably left out the modem and the antennas to safe some money. The WiFi Model is 70€ cheaper than LTE version.
I'm just necroposting because this is a very common theme, and it needs to be put to rest once and for all!
Not really. But there is a 'black box' section of the firmware and hardware that only Qualcomm has access to, the technicalities of which are under government regulation, both USA and Internationally. That is why the major portions of all Qualcomm equipped devices are actually written by Qualcomm itself, and other processor (SoC) manufacturers likewise.
If such information was disseminated to mobile device manufacturers, it would leak, and that would compromised the entire cellular system. The wifi only is nearly identical to the 4G LTE, but you will never get firmware loaded that will open up the cellular modem.
And if you actually accomplished such a task, it wouldn't be long before federal authorities were interrogating you on how you did it, and debriefing you to never mention a word of it ever again, nor using the knowledge in any way, under penalty of being legally banned from all cellular networks, permanently!
If you dig hard on the Qualcomm site, and pass a few security checks, like demonstrating you're an actual mobile device developer, you will run into these stone walls where no one is allowed to pass.
any way to use 2 sims with micro sd card ?
From my understanding not on newer Samsung dual SIM phones.
You might be able to use one SIM and the e-SIM.
You can use eSIM plus nanoSIM on s20 ultra and that will leave the microSD available. A guy on you tube showing the eSIM setup details sort of confirmed this.
I will update when I get an Ultra.
But that seems to be one of the biggest features on s20 Ultra this eSIM support and microSD with two numbers
From what I've read it may depend on the carrier software/CSC, as to whether you can use another SIM card along with the eSIM? But I can't see anything confirming that so far besides user posts at some places which seem to be more speculation than anything.
All that I can confirm for sure is, that it is possible. My carrier (Telstra, Australia) offered me both a standard SIM or eSIM when ordering, in which they said I could use another SIM freely along with the eSIM (eSIM is what I chose) I hope that's applicable for all.
They talked about this on the Samsung Forums. The international version has a hybrid slot allowing 2 nano Sims or one nano sim and MicroSD. In the US version one nano sim and MicroSD. If you use the ESim and nano sim only one can be used at a time not both. Like you can't be calling on one and texting on another. At same time.
The ability to use only one line at a time is not particular to the eSIM. My Note 8 has two nanoSIM cards and same limitation applies. When I talk on one of the cards the other is disconnected. Data comes only on one of the cards. Indeed only one has 4g connection.
I suppose s20 have similar limitations. I think this is limit as there is only one radio.
The gain is that both SIM are registered in the network and both can receive calls or be used to make calls at a given point of time but not simultaneously.
In my case both cards go to the same operator. One is from work the other is my personal number.
It works on the EU model SM-988B/DS
One nanoSIM + eSIM + MicroSD works.
I got my S20 Ultra last night and now have 256GB storage 128 built-in and 128GB SD card.
Now I have to figure if UHS-II benefits me or I stay with slow big cheap UHS-I card. Perhaps I will go to 400GB card.
So the Australian model for some reason goes one single physical sim and an esim rather than dual physical sim+ esim. Hopefully we can start a discussion to see if we can convert it to a dual physical sim by changing csc and getting a physical dual sim tray
does the phone itself has support for second physical sim?
Looking inside the slot the pins are there, but the sim holder only has space for one sim, currently, there are no replacement trays available so I can test it.
Which Country CSC code supports both dual physical sims & E-Sim?
I have a F926B and ordered the dual sim tray on Ebay, but I need to change the firmware for it to work.

Does the box they came in have 2 IMEI numbers on it and a EID ?
What carrier do you use ?

Yes. I am using Single SIM + E-SIM, but i can see double-sided connectors in the sim slot which means it can also support duel physical sims. I have the dual sim tray from the UK, but the other physical sim does not register on my MXO (Mexico) Model.

As far as I know needs to have 2 IMEI numbers on the box. 2 IMEI numbers means it supports dual sim the EID is the E-SIM
You can look under settings - about phone. If it says IMEI (Slot 1) only and no IMEI (Slot 2) then your devices does not support 2 SIM. Just because it has connectors on both sides does not mean device itself supports it. Samsung may have used same type of SIM connector but hasn't given proper dual SIM support in rest of device such motherboard and OS.
Shame on me ... I needed to read that thread here to understand, that my Z Fold 3 is capable to house two SIM cards. When I got my ZF3 a week ago, I was disappointed, that only one physical SIM slot was available (compared with the Note10+) ... I did not realize, that there are two sides on the tray (SM-F926B). So, I'm using two SIM cards with no need to wait, until my providers support the eSIM.
RTFM, I know ...
