hello
my friend have used phone from t-mobile usa
and the phone can't read any sim except orange israel (don't know about t-mobile sim)
how can it be ?
and how it can be changed that the phone will read all the sims ?
now when i try to put any sim i got message "sim card not found"
This phone requires a certain type of SIM. Different SIMs have different shapes and sizes of contact area for the chip. Compare them and you'll see what I mean.

thanks for your answer
than there is anything to do to solve this ?
from 7 different carriers orange israel will be the only one will work on this phone?
btw . i now see other post you talked about the sim sizes...
in my case the sim size is identical
but i think the chip size is different
the one that work have a larger chip
look at the bottom of the sim and make sure the metal contacts are in the same place as the tmobile sim (look up a picture of tmobile sim on google if you need it) otherwise its possible that the phone is not sim unlocked
from what i see it's not on the same place as t-mobile sim
just orange israel sim is the same as t-mobile

Take a working SIM to the carrier you want it to work with and see if they will sell you a SIM that matches that type.

i don't think they have that type of sim
because they new carriers that sell just the new one
there is no service that can unlock it to work with all the sim cards types ?
or this is done deal ?
It not the carrier type that is the issue. This is the hardware on the mobo. If your SIM reads, but the phone is carrier restricted then it will tell you. Unless you are getting a message to that effect this is H.A.R.D.W.A.R.E.

as u said , i am not getting any requset to put any pin or puk or any unlock code...
but there is one carrier that the phone read his sim card (with the bigger chip on the sim card), but it's just 1 from 7 carriers , because the others have different types of sim cards.(the one with the smallest chip on the sim card)..
what about cellphone labs ? they can't replace the part that read the sim to one that can read all the types of the chips (that on the sim cards)
i am the first that stuck with that problem ?
i really don't want to buy another phone
i like that phone
there is no solution for this hardware problem ?
thanks
Cell phone labs? What? Dude it's part of the motherboard. It's engineered for and soldered to the motherboard. You just need the correct style of SIM card.
There are dual SIM adapters out there that MAY work. You could try that, but it will require cutting of the SIMs to make them fit under the battery.

thanks again
i don't know why they bother to release phone that accept just one type of sim
that most of the phones can accept all the types
Hi Guys,
A new guy here. As per subject, I have a hybrid dual sim version of the S7 Edge.
In the SIM card manager you can select a "preferred" SIM card for voice/text/data calls, or set the phone to "always ask".
As I'm using a 2nd SIM card to call only 3 of my 500+ contacts I'd like to have the SIM 1 as preferred for everything, but somehow assign those 3 numbers to the 2nd SIM, so when I make a call it ALWAYS calls from SIM 2.
Is that possible?
Kind regards
Paul
Anyone..? I'm having same trouble...
Bump..
I've not seen a method to do this on the S5/6/7 Dual sim phones

Thanks for your reply.. That means this functionality is removed S4 onwards.. [emoji19]
If someone wants the S7 international version, the correct model is G935F.
Aside from availability, why would anyone not want to buy the dual SIM instead, G935FD? Are there any downsides to the dual SIM vs the single SIM?
No difference if you do not use 2nd sim, if you use 2nd sim then cell activity will increase obviously and risk of higher battery drain when there are poor signal strength
Not sure if your ROM modding options may also be more limited if you wish to keep 2nd sim fuctionality
I just bought one and can't figure out how to get Samsung Pay to work. The stub app is there but it always fails to download. :/ (And on Play Store, says your device is incompatible with this version.)
Other than that, I can't think of any other downsides. But I do wish Samsung Pay worked...

Samsung Pay is available only if Samsung has it officially released on your country. Or else it will show as incompatible (happens to my S6 edge)
I have one... so far so good using 1 SIM

Be aware the second sim uses the SD slot, so you can't have an SD card if you use both sims.
No downsides so far using the 2-sim model. Actually I followed a video tutorial on Youtube and got the SD card to work with both SIMs (regarding to last post).
My only worry is that maybe we won't get as much ROMs as the single SIM variant.
The main feature difference, at least between the Dual SIM international version (this one came with a lot of chinese written on the cling film phones get shipped with, default language was chinese, and even after selecting, the Dual SIM selectin menu still display still shows a couple of chinese characters) and my single sim international version (I believe it is a ME version as using Samsung info, it showed localisation to Egypt) is that the DUOS version only allows 2G/3G connectivity, there is no 4G or LTE option at all when you go into Network Mode, whereas my single SIM version allows you to choose b.w 2G only, 3G only, 3G/2G (Autoconnect) AND LTE/3G/2G (Auto connect).
I believe only SIM1 allows data, SIM2 is calls only, and its not active standby, i.e. if you're on a call on SIM1, and someone calls SIM2, they'll get a busy tone, no call waiting.
I haven't really noticed any major difference in terms of battery usage
If you're not bothered about 4G or LTE, then the Dual Sim is the way to go. It IS possible, with a bit of DIY to use 2 SIMs AND the SD Card at the same time.

Thanks for mentioning that YouTube. I was curious and found one instruction: https://youtu.be/GpRaHpF3cNI. It quite a surgical procedure but doable.
Any 93xF ROM works on the corresponding FD variant.

SIM 1: 4G
SIM 2: 2G only
That's on the S7 specs page (HK or Chinese site). You could also see the youtube video above. Toward the end it's showing exactly that.

Absolutely incorrect information;
I am using G935FD. Both the sim's are 4G Capable.
Any one 4G Sim is active at a time as it is a technology limitation and not phone.
Also can receive call on both sims simultaneously and there is a special setting for same.
And Yes you can use 2 sims and a SD Card together with some efforts.

At first I was going to say that your post is totally false, but then I realized that you have the Chinese/HK SD820 935FD version....
On the Exynos version, contrary to common belief, LTE/4G/3G/2G is ALLOWED on BOTH SIMs..... BUT ONLY 1 CAN HAVE DATA AT A TIME. See attached pics. I've already proven this by using two different SIMs, both with data, in different configurations (1 at a time, both inserted, swapped), and sure enough, SIM2 is capable of DATA.
So SIM2 is NOT JUST CALLS ONLY.
Difference in battery? Don't know really. Haven't been using both SIMs simultaneously enough to make a sound judgement.
The fact that you CAN use DUAL SIM & Micro SD at the same time (with a bit of work), AND have LTE on either SIM, AND be able to root/TWRP/custom ROM - the Exynos 935FD is the way to go....
In the messages app you will see either the sim 1 or sim 2 icon to show which sim you sent the messages with. Thankfully it doesn't show in the status bar

You meant *partially* incorrect, not absolutely as if everything I said was incorrect.
Glad you can chime in.
Hello, I planning to buy a Galaxy S7 Edge with dual-sim and have read that originally only one sim of two can be active (other stays inactive). So my question would be : Is there a ROM in which would be active both sim-cards ? Thanks for little help.
That's correct. If you are on a call with SIM 1, SIM2 won't be inactive.
I'm not sure if there's any way to change this. I would guess it's a hardware/firmware function that cannot be modified.
Does anyone know if you can replace the sim tray on US branded S10's with a dual sim tray from the Global? And would the Dual SIM feature work?

Usually it doesn't work that way as there should be pins connected to the motherboard inside the phone for the second sim card.

If they make a conversion for the S10 then of course it would work. It worked for the S7 and S8, but without looking I don't know what version phone they're making the conversions for but I know that Simore and MagicSim made adapters for the older model phones. You need to realize though that it's dual sim standby and not active dual sim since both Sims will be sharing one modem and only one can be used at a time.
