Single SIM to dual SIM - Nokia 8 Questions & Answers

Hey guys,
This is sort of an odd question but I thought it would be worth asking anyway.
I recently bought this phone but then realised it's the single SIM variant. At the time of purchase I didn't appreciate there were two versions. I mean, even the manual says you can put a second SIM instead of the memory card.
Anyway as you can imagine this is very annoying because the shop won't take the phone back "just because". So I looked on eBay and I can buy the dual SIM variant SIM tray.
Do you think I can just replace the single SIM tray with the dual SIM tray and use two SIM cards like a champ? I guess the OS wouldn't recognise the second SIM, would it?
I'd be grateful if someone could shed some light on this issue and let me know what my options are (if any).
Cheers

I mean that is impossible, but you can try to ask a question to Nokia support, maybe

I think it's not possible, dual sims are being flashed with a different firmware version from HMD. Let us know.

Differeent rom flashed? Ok but then this must be because of the second imei that got to be written somewhere in a flash partition. Would the Android os-code be really that different?

I think it would not be possible not because of the different firmware or missing imei2 but because of a possibly missing sim2 slot connection
Check attached pictures of the different sim trays attached and an inside view of the sim slot!

The second IMEI exists!
Trying to type the code *#06# I've found two IMEI number for my TA-1004.
In Settings -> Network menù, there is SIM Cards section
The only test to do is to buy the dual sim tray and check if it works.

dual sim

hello all. this question may be stupid, but esentially for me: can i made 2 sim cards to work both on my diamond in the same time? I mean to can receive a call on the orange sim card and to receive also to vodafone sim card without to be need to change the sims, or to change the operator? to function both.
I guess there are a couple of mobiles (with two antennas) able to do that (seen one, can't remember the brand and model). With only one antenna what you can do is clone both SIM cards into just one and with a reboot you have the option of starting up with one network or the other (I reckon you can have more than 2). I don't know if it's possible with current SIM cards and can't remember the hardware and software needed to do that.
Oh.. And it's illegal The best option is to have more than one mobile
yes i know about that devices that have 2 antenna's. i was wondering if i can do it on diamond. i know also about that method with 2 sim and after restart to choose the network operator. thx for the answer.

Exynos Note 8 models are (probably) all dual SIM hardware - see pic

Just to put to rest the rumor that the hardware is different, here is a picture of the SIM/SD slot on my N950N (Korean single SIM model), which you can clearly see both SIM slot pins, as well as the SD pins.
Mind you the single SIM models only come with one IMEI so I have no idea if you can use one for a dual SIM setup, but the hardware most certainly is the same.
Also, bonus pic showing that this part is apparently labeled for an N95OU which is the north American Snapdragon model. Must be sharing quite a few parts even with those ones eh?
Hi Kalm_Traveler,
I buy a N95OU1 north American Snapdragon model. I buy a dual SIM tray in Amazon. How can I make the 2 SIMs works? It's possible?

That's the thing, as Kalm_Traveler is pointing out, you only have one IMEI. Dual sim phones have 2 IMEIs. How would you obtain a second IMEI to use to use legally? And you would need root access to configure it to work even if you did happen to have a second IMEI to use.

I legally own 3 old phones (Blackberry & other model) where I could easily get valid and, again, perfectly legal IMEI's;
so besides the legal concern, which does not apply in this case, it would be interesting to know if it's possible (or will be) to root the phone and enable somehow its dual sim capability having a 2nd IMEI (owned and legal) available to set up.
If the hardware is really the same we have just to wait, maybe

Try changing this line in build.prop and see what happens.
ro.multisim.simslotcount=1
To
ro.multisim.simslotcount=2

On my Note8 monosim brand HUI Italia and rebrand Vodafone Italia in build.prop have already line ro.multisim.simslotcount=2 but not have any menu for dualsim. My phone not have root access.
To make the menus appear, do you need the dualsim cart?

On my N950U1 (Snapdragon US Samsung unlocked, non-dual SIM), using Shortcut Master app, I found the working dual sim menu. See attached ss.
So also SD Notes could be dual sim capable.

Can you please tell me how to do it? I own the sm-n950f single sim European version.
1. Install Shortcut Master (lite) from Google Play.
2. Select 'app explorer' from menu.
Select 'system apps' from pull down list.
3. Scroll down to and select
'Mobile networks' (com.samsung.networkui),
4. Scroll down to and select
'MobileNetworkSettingsTab' (com.samsung.networkui.MobileNetworkSettingsTab)
5. Press 'Launch'
I have not been able to actually test whether 2nd slot works, as I am waiting on delivery of dual-SIM tray...
I don't think it has the software to work - you would need to have some way to add Stk2, and more importantly the libsec-ril-dsds.so libraries.
Your probably right, but will see what happens when $3 tray arrives ...

Thank you so much for your help! Did you flash the dual sim rom yet ? I have also read at the forum that it actually works but we need to change some files with the similar of the dual version. (https://forum.xda-developers.com/galaxy-note-8/help/galaxy-note-8-n950f-modding-dual-sim-t3685255) May i ask where did you get the dual sim tray from? Here in Greece it's unavailable. Thanks again and i hope everything goes well!
I did not flash anything yet... As I have SD, will /can not root easily..
Just search 'SIM tray Note 8' on Ebay...
Ok i have already subscribed to this subject so if you receive the tray and you make the dual sim work please write something here so that I will try it also to my device. (please forgive my English)
Thanks again for your support and best wishes to you for 2018!
wonder if you can just flash the duos firmware without root if you have the OEM unlock option available and get a dual sim tray?

same on my unlocked exynos model
ok, scratch my first question, firmware is the same for both Single and Duos anyway.
I have a second dual sim tray coming in the post and also have an old Samsung phone I can use imei number from to be legit so will take it from there, once I set up my dual sim I don't think I'll mind rooting this single sim as you still get OTA as long as you don't install custom Rom
just did a quick check here in case it helps anyone...
took the tray out of my dual sim to stick into my single sim Note, dual tray won't go in unless I put a sim into slot one so did that with an old inactive one and put my own sim into tray 2, rebooted just for the sake of it, can still make and take calls etc... but looking at sim info in settings... about phone... it showed sim as inactive and no mac address, I'll try with 2 active Sims when I get my hands on one over the next days.
Hopefully any small info gathered can help determine how easy/hard it will be to get dual sim out of single sim
@Kalm_Traveler looks like you'll need to add dual sim capabilities to your zip once you get wifi calling working xD
On the N950F, could it perhaps be as simple as installing a dual SIM tray and then flashing the N950FD firmware? Or just editing some files on the current firmware.
Maybe the second IMEI will come from the hardware?

Single Sim phone with two IMEI numbers

Hi, i'm looking for an answer.
My xz3 is single sim model but in settings you can see that i have two IMEI numbers, mabye there is an option to rebuild it to support two sim cards?
Edit: just checked that, it's dual sim phone, in PLUS(polish vendor) was sold as single sim version.

Dual sim version showing only 1 IMEI?

Hello everyone. So i bought a used Moto g6 3gb variant from market last night. So far good experience with the phone so far except one thing.
It was sold to me from dealer saying its a single sim variant but when i came back home it had 2 sims + card options in the tray so i've searched the IMEI on various sites and turns out its a XT1925-2 so it is indeed a dual sim variant.
But when i put *#06# on Dialer it just shows me 1 IMEI number instead of 2? How is this possible?
I could be mixing this up, but I thought the IMEI is based on the device and not the SIM, so a dual SIM device would still have just one IMEI?

Dual-SIM devices are supposed to have two IMEIs. You can't have two SIMs on one IMEI. Avoids problems.
Anyone? Why my cellphone has 2 sim options when theres only 1 IMEI? Is this the work of gypsies? xDDD
Could be that the phone was originally single sim but then flashed with dual sim firmware and had the tray replaced with a dual sim tray. I'm actually waiting on my dual sim tray to do the same on my xperia xz2
SIM TRAY
You can find both imeis on SIM TRAY.
I bought Galaxy S9 plus with dual sim G965FD, and it has same identical imei numbers for both sim slots. I am confused how? Both sim cards are working fine.
I'm having the same issue on my moto g4 after flashing the stock rom usually whenever I flashed the stock rom earlier my imei's turned down to 0 but this time only one imei is showing and even in the settings I'm getting one sim please help
Not the same phone, but I owned two Xiaomi Redmi Note 3 (broke the first one after a month...). The first one had different IMEI for each slot. The 2nd one had the same IMEI for each slot. Despite the oddity, I have not run into any issue by using two SIMs in the last 3 years.

please send me imei in a private message. i know a way to find correct details through imei.
too late but maybe is not original phone but chainaillegal copy on mediatek
well after all, imei is more like just an identification of your device for the antennas, so there should be no problem it is as if you just swap your sim card every time you want to use one or the other number, so I dont think there should be any problem using a single IMEI

Question Help me fix it

Hello guys. I bought a s21 ultra 9980 512gb.
However, i cant use it with sim card as its not detecting the network. I dont get it what could be the problem. I cant even untick the automatic network search as i get error.
Will post you guys here some photos maybe you can help me out. I dont think is locked because i dont get any message when i insert sim to enter the unlock code. What could be the problem?
Please help. Thx
Are you sure its an active sim card?
Yes. I have the card in an iphone as its my current sim..

Is the Samsung running official FW?
Yes… original .
do you still have the imei number present in the settings and if you type *#06# ?
Might be sim locked by the carrier, you could theoretically still use the esim I believe if it isn't giving you an option to enter an unlock code.
Yes.. both imei show up.
How can i check for sure its sim locked?
Also, when i insert any sim, for one second the “no signal sign” near the battery goes away then comes back instant.. and it doesnt ask for any pin…
Thanks for your inputs
I have read about this issue before as well. Is this a "dual sim" model? Try the other slot if it is, and also try leaving the sim in and rebooting. You could also try "reset network settings" under settings. I'll have a look to see if I can find the thread where people said they had a fix.
is it yours from brand new? and have you checked to see if it black listed? also, there seems to be an issue with some Samsung where they are forced into airplane mode the only way you see this is the notification panel the airplane model toggle is half-lit blue I could be something to do with that. Failing that it could also be if you have dropped the device the ribbon may have come loose as this is a common issue with Samsung a range and that's all I'm seeming to fix lately
Hello. No, didnt buy new. I got it used.Yes its dual sim model. It doesnt appear as blacklisted.
Its not in airplane mode for sure. Also i did factory reset and also wrote all stock firmware ap cm bl csc from samfirmware..but its the same as before.
Also, esim doesnt show up under the sim card manager.
try *#2263#* to change bands, or *#0011#
Maybe also try to put the sim in the other slot, and see what happens. If all the same, try someone elses SIM card for a minute to see. Maybe your sim has become slightly damaged but your iphone still manages to read it, while for some reason the s21 is not managing.
Just tried the sim in my sisters s20 and works. Also tried her sim into this new phone and same . Even if i put in sim1 or sim2.

Found this online:
"In Settings go to network mode and set this to 3G only. Then restart your phone. This works in my case."
Thanks for your sugestion. But its the same…
I had the same issue on single sim korean unit...but factory reset resolved the issue. Actually i used to disable carrier apps which was causing this issue.
