Hi guys,
I have a single SIM Z3, and would like to pick up a dual sim one for my travels.
I understand that all aspects of the Z3 and dual are essentially the same, but I do have some questions.
1. Where does the second sim go? - my single sim version looks like it wouldnt have space to accomodate 2 sims and a microsd? is the flap on a Z3 dual longer? - issues with cases, etc?
2. In terms of dual sim management, I understand only 1 sim is on 3G/LTE, but can the second sim be connected to a 3G network (with no data), or is it strictly going to be on 2G? in addition, can you assign the SIMs for either role electronically, or would you have to remove sims and swap the slots that they are in?
thanks!
Hi,
The dual sim slot is on the right side above the power on button. Micro sd slot together with the micro usb slot is on the left in one flap.
Regarding the LTE/3G or 2G network, both sim slot can be used for either 3G or 2G which mean if you assign the first sim to be on 3G, the other will automatically switch to run on 2G which mean no need to swap the slot. You can choose in the settings menu which sim card to use for data.
Im using my Z3 dual with two sim cards as i am working oversea , so i have been experimenting with it, and it work just like any other dual sim variant phone.

Kyo, thanks for your response. Surely that means the left flap with the MicroSD and MicroUSB is bigger than a single SIM Z3 (I'm assuming you've seen a single sim Z3) - and by how much? Conscious of case compatibility.
Did you pick yours up retail or online?
thanks!

It's quite easy, just compare the flap on your z3, the size of left flap and the right flap & you will know how much difference. I can tell you for the dual sim z3, both side of the flap is same size, but the left flap is positioned lower about 5mm lower than the right flap. Thus, it is definitely not compatible with your current case for the left flap, as for the right flap maybe it should fit the hole on ur case i guess.
FYI, I don't have a case installed yet, but i have ordered a casing, which i suppose is not compatible for the flap as most cases out there are made for single sim z3. But, i don't need to open the flap often anyway..so not a big deal for me.
I bought my z3 online from a local retailer (Malaysia). I think it is imported from HK.
Hello everybody...
Anyone knows if is possible convert a normal N910c in a dual Sim version of Galaxy Note 4 N9100? I just thinking, if is possible of course, change the the normal flex part that hold one Sim card for a new one with a double Sim card holder and change the middle housing too, for the same as N9100 uses to fit the new parts. On eBay I find this two parts, anyone have some idea if this is gonna work? Is necessary some firmware implements? The Note 4 is a awesome smartphone and I noob here just thinking if this go work with it.
Thanks people. You're the best.
The parts on sale in eBay. I can't post the links to this part here, noob haha, but if you wanna know who are this part, search on eBay for "OEM Double SIM Card SD Card Holder Flex Repair For Samsung Galaxy Note 4/N9108W" and "For Samsung Galaxy Note 4 N9100 N910F N910X Battery back Full Housing Cover Door".
That's all.
Mmm not really... at least not with these parts. There's a chance to convert it but I'm sure that you would need to buy the main dual-sim pcb and the back housing itself. The double sim flex will not work in the N910C mainboard. Cheers!
Do you think I need a new mainboard to this work? I was thinking that Samsung use a universal mainboard and add new components to her to build the different models...
Well first of all both N9108W/N91000 are snapdragon variants while our N910C is an exynos one. If you're able to snap the dual sim board in the PCB, you will still need to use a dual sim-enabled firmware, and the only available dual-sim firmwares are for snapdragon processors so it will not work in your device. That's why you should buy a N91000 Snapdragon pcb and swap your Exynos one. Cheers!
Ok, I understand it, not worth the effort, is more easy change between models and I don't need to do this... But it was curious if this would work. Thanks!!!
There is actually a dual sim adapter for that. It's available for most phones, I used it for my Note 2 but the flex cable was too thick so it kinda bulged when I forced the adapter under the battery cover.

I know those adapters, but you need switch with them to receive the signal of one or another operator, right? Or both sim works the same time?

I THINK they work together. I can't confirm it as those adapters works on stock roms and I was using custom, so there was some issues trying to detect the sims.

simply not possible
Nope, unless you are a software developer and can alter the stock firmware for your N910C to support the use of dual SIMs.
Hey guys,
i will come back to the Topic from the opner.
i have the Galaxy Note 4 SM-910F with a Snapdragon 805 CPU, in this case i think that can be work.
But i thik the firmware / baseband must be changed to the firmware from the N9100 / N9108W.
Perhaps also the kernel?
A genius idea!
Someone found S7E indeed can read Dual SIM with SdCard running at the same time.
So simply peek off the golden part of the SIM and stick it to a SdCard, then put it together with another SIM onto the tray. Magic happens! :good:
Is there any gladiator brave enough to try?
If this works, if definitely will buy a S7E!!!

This is an old idea and much popular between Huawei Customers as they always lauch these type of dual sim phones and i also tried it on P8 Lite

Can you tell us More? I'm waiting for my SD card to arrive and do this. I already practised on a broken sim card and I could fit it into my phone and out
It works on my S7E bought in Hong Kong. A bit tight pushing the tray back into the phone as it does add a tiny bit of thickness to the SD card. In fact so snugged that I haven't got the guts to take the tray out again!

Thanks for the feedback. I actually tested a broken SD card and sim card. I used a hand file to smooth the edges and it worked very well. I'm ready to go now.
tested working on S7 Edge Singapore. 1 Main SIM and roaming sim with microsd card.
I wonder if any brave user from this thread tried to eject again the sim tray with the microsd/sim2 mod?
tried it once since i put a wrong sim card on SIM 1. a bit tight, but after it pull out using the sim tray pin, i just pull it carefully. I just remember how my sim tray was stucked on my htc one x because of the microsim i cute with a little thicker than newer sim card. cannot be pushed by the sim tray pin anymore since the button inside is stucked.
I just tried to use 2 SIM card with a brand new evo+ 64gb SD card on my s7 edge dual today, I burned my 2nd SIM card and took out the chip from the sim card, glued the chip on the back of the sd card that I have sanded down. THE RESULT WAS DISASTROUS. I ENDED UP WITH A WRECKED SD CARD AND AN USELESS SIM CARD = 40 bucks down the drain :crying::crying:

why the FFF would you do that? burned the Sim card? you already lost that. Sanded down the SD card? you broke that too.
you should not slim down the SD card AT ALL. the upper layer of the SD card is just a paint on the board.
you should cut out the SiM card carefully and don't damage the small part in the back covered by a drop of glue. then slim down that drop of glue carefully and stop before you hit the small board inside.
then carefully cut the side a little before gluing it to the SD card. then try to smooth out the corners and sides VERY carefully to make sure while pushing in and pulling out it won't stock somewhere.

I found this tutorial video on YouTube and was going through with it step by step. However it suggested to use an sandpapaer for thinning down the sdcard i didnt have that so i used the filer of the back of a nail clipper instead :crying: anyways I don't recommend for folks to try it unless you've got some spares sdcards and SIM cards lying around.

i did this successfully without burning or heating the sim card. what i did is just trim down the side of the sim card until the gold portion remains and until there is a little separation gap is seen from the gold module to the plastic. i removed the plastic part by a very thin cutter on the edges until i can fully pull it out on the plastic. removed the dried glue from the sim chip and taped it on my microsd card.
i didn't use also a glue to do this. I just used a very thin double sided tape. put small portion of tape on 2 sides of the sim only. i didn't put the tape on the middle chip area so that the thickness still minimized.
even though i'm waiting for my 200GB micro SD card, i just told my brother how to do it, and he successfully did it. 128GB SD card and 2 Sim cards are working on his phone now.
the only thing with running dual sim, 1 sim only runs in 2g... not many carriers support 2g anymore.. lolol
it's only for s7 edge dual sim variant, or work fine in single sim also?
i want to do in my g935f

You need a dual sim phone.
did not work
my uncle just returned from uae with the dual sim version s7 edge....I myself have a uk model s7 edge, using his sim adaptor with the 2 sims I put it into my uk s7 edge did not work!
any suggestions

I think u will need a dual sim phone to be able to use two sims.

It's not just the sim tray that is different. The electronics inside the phone to read 2 sims are only present in the dual sim versions.
Question though, have people successfully pulled out this modded sim tray without damaging the cards or phone?

The electronics are identical, there's a dual sim reader in a single sim phone, problem is you only get one imei.

Tried it once. because the first time I inserted the modded microsd, i inserted also a wrong sim on sim 1. I have no choice but to pull it out. the microsd didnt and sim tray didnt break. but it is a little more tighter than without the modded microsd card. I think it will depend on the thickness of the microsd and how you glued the sim chip to it. if you glued it too many, it might be a little thicker.
Just be careful not to push the sim tray pin to the hole too hard. it might be stuck and the tray cannot be pulled out anymore. tried it on my htc one x before. I cut a old sim to microsim. since it was an old sim, it is a little thicker than the newer microsim. i pushed the sim tray pin to the hole too hard and it got stuck. good thing i can pull the sim tray by fingernail. but this will not happen on once it will be stucked on s7 as the top portion of the phone is flat and cannot put anything to pull it out.
I have an unlocked Samsung Galaxy S7, (not edge) G930U that I purchased on ebay. I foolishly expected that since I was buying a flagship phone, I would get dual sim cabability. I was clearly proven wrong. I have however seen a hack that showed that an additional sim can be added, by removing the metal bit from the plastic and glueing it to a micro-sd card; and placing it in the micro-sd card slot in the single sim tray. I tried an alternative route of purchasing a proper dual sim tray from a mobile phone store; and this didn't work. It fit perfectly and sim 1 and the micro-sd card worked perfectly; but the mobo wouldn't regcognize sim 2. The theory of the hack being that the S7 mobo is already internally hardwired for dual sim, it's just that this feature has been hidden or deactivated.
So what I'd like to know, is this hack just BS, or do I simply have the wrong phone? Does the G930U mobo NOT have dual sim capability. It might also be a matter of critical dimensions, that were met with the hack but not met with my method. Pehaps the dual -sim cicuit pads are there on the mobo; but the contact fingers are not; which is why forcing sim 2 down a few 1/1000s, by glueing it to the 'bottom' of the micro-sd card works. And a nornal two sim tray doesn't. Any insight appreciated.
Can I just take this phone to a mobile store and have them crack-it-open and add the fingers, or replace the mobo? Sure, I can replace the phone, with a dual sim edge; but they're kind-of delicate and kind-of suck, especially if you have to repair one. Besides, I got a great discount by purchasing a refurbished one
SiMORE
has several 'add-on' options available; but I don't like any of them. I don't want to have to add an attachement or carry around an extra box. I just want my 'flagship' phone to be dual sim. This just makes sense in a 'mobile' environment. If you need to use Uber or Taxify and your carrier isn't performing as needed, in that location, you need to have a sim 2 (second carrier) option, period.
To my knowledge the US models never had a duo variant, they have a different SoC with a different mobo that has no hardware support for it.
While it is true if you have the international model you can hack it to see 2 SIM's since it's the same mobo as the duo, it means you have to falsify or steal an IMEI for the second SIM to use, which is illegal and you won't be allowed to discuss it here.
You can get a G930FD which is the S7 flat (not edge) international dual SIM model with the Exynos SoC, but the US doesn't use this model so your network compatibility may vary.
All versions of hardware Samsung S7 have dual sim tray
ifixit.com/Teardown/Samsung+Galaxy+S7+Teardown/56686
amazon.com/Reader-Holder-Socket-Samsung-Galaxy/dp/B074YHQ1WM
But now noone can convert ss S7 based on Snapdragon to dual sim support.
Looking at a Samsung Galaxy S10e SM-G970F, but seller doesn't know if it's dual or single SIM.
If it shows 2 IMEIs, one with SLOT 1 and the other SLOT 2, is it for sure dual SIM? Or could a single SIM also show that for some odd reason?
I told the seller to check the SIM tray for "SIM 2" printed under "microSD", but he hasn't got back to me.
