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

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.
I acquired this phone second hand but like new from an elderly lady. When she/someone on her behalf removed the sim card, they tore the sim card slot/cage right off.
I see lots of replacement parts on ebay / aliexpress for other phones, but I can't find one for this model. Looking for a little help in sourcing it.
I have a phone on order (HTC 10) that takes a Nano SIM (4FF). My current HTC One (M7) has a Micro SIM (3FF), but looking at it, it appears as though a nano SIM (4FF) could be broken out from the Micro SIM (3FF), much in the way that many mini-SIM cards (2FF) can "break out" to become a Micro SIM (3FF).
Does this sound possible? I hope it's not too confusing how I have tried to posit the question. I'd like to be able to transform the micro SIM to a nano SIM when the new phone arrives without going to the T-Mobile Store.
Thanks.

I don't think you can because with a micro SIM the contacts come almost completely to the edge, trying to go smaller would compromise the contact area. Go to the store, there's a right way to do things and a wrong way to do things, engineering an alternate solution is only necessary when none already exist, in your case, alternatives exist.
This may help

Take your chances and trim a micro SIM to nano size but I'll wager you'll have issues and have to get a proper nano SIM anyway. The correct SIM shouldn't cost you anything from your carrier if you're paying for cell service on their network. Why complicate it?

Does some of you know if single sim motherboard fits the dual sim htc u11... Can't find any information about its dimensions.
I have my almost new htc u11 with audio ic failure, and cant find broken dual sim variant to buy, only single sim on AliExpress...
Thanks in advance
Without being 100% sure, going by standard business logic and production facilities methods, it should fit just fine.
No company would decide to spend more money ( thus using two separate production lines ) for 2 products that can be made to be manufactured on the same line.
As far as I remember, some people were trying to turn Single SIM u11's to dual sim and the only difference they noticed on the motherboard was the missing sim 2 connector/contacts.
So yes, it should fit just fine.
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.
