Is dual SIM and Adaptive/Merged Storage possible on this phone? - Samsung Galaxy S9 Questions & Answers

My current phone is the Samsung S7 EDGE with a 200GB sdcard and dual SIM. I achieved this by sticking the SIM chip on top of the Sdcard and following Paul Obriens thread for merged storage.
Its time for me to buy a new phone after 2 great years with the S7. I see the S9 SM-G960F/DS 128GB phone and was wondering if it is possible to run both SIMs and the SDCard by similare modification as to the S7.
Anyone know if this is possble or with the 128/256GB version is it even necessary to insert an SDCard??
Thanx
angusc.

Sim card reader on SM-T830.

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.

2 SIM cards with SD card not working

I'm coming across from the Note 8 and I have been running two sims plus an SD card inbthe hybrid slot. When I install the same in the Note 10 it says something is wrong with the Sim tray slot. There is zero function of the phone till I remove the Aim card slot.
Does anyone know why it won't work in the Note 10 or someone has it working?
Thanks

Unfortunately Samsung stopped this from happening.
Now, if all circuits (2x sim and 1x sd card) are detected in use, the device displays the Sim tray error and prevents you using the device until you remove either a sim card or the sd card.
This was introduced on Note 8 on certain firmwares and now applies to all newer released hybrid sim devices.
I'm guessing this is to avoid users damaging their devices as the hybrid sim tray was never designed to support all 3 circuits at once and did require some skill to ensure sim tray could still be inserted/removed.
I too was annoyed this happened, but can understand it is to prevent warranty issues.

It's there a way to get around this?
So what I managed to do if anyone else is in the same situation as me is. I took the sim/SD out and I can't remove the sim card from the SD card because the SD card holds it in the correct place. So I just copied all data off the SD card and painted over the connector of the SD card so it won't detect it, and now it only detects the Sim card. So both Sims are working now.
When there is a work around I will do that and use some paint remover to clear the connections of the SD card. But I do have a 1000gb SD card waiting to be filed and replace this one. I didn't use tape because I was too afraid it might come off and get stuck inside.
Because this sim is from a different country where my internet banking is linked to, is very important to have and because I dont go back to that country for 2 months I can't just ask for a replacement. So this is my best case for now.

Dual sim and memory card block

Is there still a version of OS that allows any mode to run 2 sims and a microSD card? Hopefully that runs dex as well.
I read comments on the club sim in Hong Kong, but I don’t know if this is only for 1010, where the sim is available in 128Gb format, and supposedly the devices would allow that. I don’t see how it would be possible.
Anyway, any solution that allows running dual sim and SD card on a Note or S series?
Thanks,

use 2 sims and micro SD card

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.

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

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?
