[Nexus 6P General] FuMMoD:
Is the potential second slot recessed at all like the original sim slot?
[Nexus 6P General] r32inc:
Here's the other side.
[Nexus 6P General] Phazmos:
Is it me, or is the 2nd slot not notched like the primary?
[Nexus 6P General] 640k:
i can't see the detail. is there a "bracket" for the SIM card to rest in? what i'm getting at there is, could the SIM just be shoved/slid down in the lower portion?
[Nexus 6P General] a7ad67:
Any update
[Nexus 6P General] cliff p:
Unfortunately, the time has come to put the testing and modification to a close. While he still believes he could reach a solution, he no longer has the time to dedicate to the testing and writing the kernel.

If anyone wishes to continue the testing, I will provide whatever notes and code he has written, so long as he is willing to provide it (I'm sure it's not a problem).

Sorry :(

[Nexus 6P General] drago10029:
So did someone else pick up the project? just curious, i have no skills too offer unfortunately.
[Nexus 6P General] cliff p:
No one has contacted me thus far.
[Nexus 6P General] Skreelink:
I'd love to give it a go, but I lack all the hardware and software required for some of the legal gray areas. (Such as trying to clone the imei to the second slot, or setting to 0).
[Nexus 6P General] amcferrin90:
Trying a tag here

Question for those here. I've read a lot of your discussion about the dual sim slot and trying to get it working. Somewhere around page 27 caught my google search where I'm looking for a .MBN file to use with QPST QFIL. This is totally unrelated to this thread but you all kept throwing around things my phone is doing so maybe you can help me.

My phone is in a state where the display will not turn on, I cannot enter fastboot, the phone does not show up with either fastboot/adb devices command but the Qualcomm QDLoader 9008 COM6 does show up in the device manager. I've managed to get my hands on QPST with QFIL and a couple other flash tools that are alleged to do the same repair. What I am missing is a firmware image which is supposed to recreate the bootloader and fastboot which would then allow me to push a ROM to the device and flash away. It is rumored that I need a .MBN file to do this. I do not have a backup of my EFS, I've read if it gets borked to wipe it and the phone will recreate it properly. Can you offer any assistance or guidance?

Thank you.

I only have the file that tenfar shared to me.

I don't know whether it would works.The package seems just for old qualcomm software.And it doesn't include EFS.Hope your fsg partition doesn't fail.

I think you should send it back to google for RMA.That is the best solution for now.There is a rumor that some nexus 6p have hardware failure,the emmc has soldering problem.Some people who used this phone in China had met this problem.
[Nexus 6P General] amcferrin90:
I tried that link earlier, it's been removed. I tried Google and Huawei, they refused which I thought was odd. Two things I need, SPC and flash image file and some sort of XML file, probably tells the QFIL what to do. Seems just like my Galaxy phones when they got really borked, Odin fixed them.
[Nexus 6P General] akaHardison:
Then buy a new phone.I have switched to iphone,it was pretty good though.
[Nexus 6P General] tenfar:
i will upload a firmware later today, you can try to fix it using MiFlash ,since your device is in 9008 EDL mode.

[Nexus 6P General] GalaxyIV:
have any a good news?
[Nexus 6P General] E:V:A:
Interesting topic, but TL;DR. Would have been great if [MENTION=1632145]FuMMoD[/MENTION] could update the OP with currently know info and what's been tested.

In poarticular I'd try to copy many of the `getprops` from a working Huawei dual sim phone. I can only assume this is the first thing you have tried. Right?

Particularly important are the ones starting with gsm.*... such as:

[gsm.check_is_single_pdp_sub1]: [false]
[gsm.check_is_single_pdp_sub2]: [true]
[gsm.current.phone-type]: [1,1]
[gsm.data.gsm_only_not_allow_ps]: [,false]
[gsm.network.type]: [Unknown,LTE] *
[gsm.operator.alpha]: [,Tre]
[gsm.operator.iso-country]: [,en]
[gsm.operator.isroaming]: [false,false]
[gsm.operator.numeric]: [,2xxxx]
...
[persist.dsds.enabled]: [true]

[persist.radio.msim.stackid_0]: [1]
[persist.radio.msim.stackid_1]: [0]
[persist.radio.multisim.config]: [dsds]
...
[ro.config.dsds_mode]: [umts_gsm] *
[ro.dual.sim.phone]: [true]
[ro.multi.rid]: [true]
[ro.multi.rild]: [true]
...
etc

(This was for a DS phone where 2nd sim is not used...)

Anyway, you get the idea, there are plenty more that I've missed.

[Nexus 6P General] Briadark:
Is there any progress on making the phone dual SIM? :)
[Nexus 6P General] galaxys:
No, it's been abandoned.:(
[Nexus 6P General] ahasbini:
Is there any SIM adapter with radio components built in that could be connected via the USB C port of the Nexus 6p and sort of emulate the second SIM?
[Nexus 6P General] os_man:
No need for two antennas, every Chinese Qualcomm phones with dual sim slots i have opened so far have only 1 antenna, not 2.
[Nexus 6P General] os_man:
"msm8994 modem source code", maybe i can help with this, here is the list, any useful file ?
[Nexus 6P General] Debuffer:
My device recognizes my SIM at "slot 1" but I get No Service no matter what I do. Is there a way I can achieve the SIM 2 to try fixing this problem?
[Nexus 6P General] i42o:
let this die! nothing was ever gonna come out of this... the guy who's dad was "helping" knew there was nothing they can do to make this work
[Nexus 6P General] Debuffer:
Anyway I still search for a fix for it.
[Nexus 6P General] galaxys:
Take a look at Post#402 thru 413 about extender cables... maybe some information there to help.
[Nexus 6P General] Debuffer:
Which page is it at? I can't locale it via XDA App.
[Nexus 6P General] galaxys:
My pages are not default settings, it's custom 40 threads per page. Best you search "cable"
[Nexus 6P General] fuadhdmini:
Do you have all the required figures for printing?

I lost my sim tray and couldnt find the sim tray replacement locally. While for online shopping, the price for shipper is bigger than the tray's price so im thinking of having the tray printed instead of buying the replacement part.
[Nexus 6P General] RagedElimanator:
Hey there is there any chance I can try to finish where he left off, I think it would be fun and a great teaching experience?
[Nexus 6P General] jigsawcrank:
I tried to do it like this, but softwarewise the nexus 6p won't recognise the 2nd https://imgur.com/a/r4UUwgj
[Nexus 6P General] r32inc:
there's a cavity about one 1 mm where the sim rest. can't do much for the detail on the picture here at my desk at work sorry.
[Nexus 6P General] 640k:
can you try putting your SIM in it? it doesn't appear as if the bracket would interfere with the SIM based on the pics. which side are the contacts exposed (bracket or non bracket)?
[Nexus 6P General] TonyHoyle:
You can't put a SIM in the bottom half.. there's no 'in' to put it. Even if you cut away the middle part the remaining hole is too narrow and needs to be widened about 1mm each side (to match the top half it'd have to be cut away carefully to form a ledge for the SIM to rest on).
[Nexus 6P General] stennett:
Looking forward to see what the outcome of this is.
[Nexus 6P General] magooo:
I sent an email to huawei press center. Hope they're cooperative :D
[Nexus 6P General] FuMMoD:
I receive my device Monday and I have a few extra tmobile Sims I'm willing to sacrifice lol.
[Nexus 6P General] Alferboy:
Well.. Well.. Best first attack would be to take a look at the "Vendor" partition. If it's like other Huaweis it'd have like "hw/eu-single" and it'd be a matter of flashing "hw/eu" to that partition.

That did the trick on my P8lite ;)
[Nexus 6P General] Rainstalk:
Why is it assumed to be a dual-sim and not a micro-SD?
[Nexus 6P General] FuMMoD:
Because of the pins.
[Nexus 6P General] jpmadeira:

Interesting thread - Would be a golden find!
[Nexus 6P General] Poke_N_PDA:
I'm surprised the ifixit treat down made no mention of the dual sim design.
[Nexus 6P General] yomomma7826:
They kind of did, but without actually saying anything. Here you can see that the dual sim is actually there.
[Nexus 6P General] kirandanduprolu:
The guy in the video below talks about a dual sim card slot on the Nexus 6p though one of them appears to be unusable.

https://youtu.be/zmNryj9pxFo?t=427
[Nexus 6P General] Steb6891:
Is it me of does that video not work?
[Nexus 6P General] r32inc:
Works for me. It maybe just you.
[Nexus 6P General] Steb6891:
Thanks Tapatalk is buggy as. Worked on my PC.
[Nexus 6P General] magooo:
Seems like it's now all up to a early hero with programming skills who will try to bring the second sim to life. :fingers-crossed:
[Nexus 6P General] TonyHoyle:
The biggest problem at the moment is getting/3d printing the tray for it. The software side probably isn't that hard, provided it's actually physically connected.
[Nexus 6P General] 640k:
maybe? if earlier videos are any indication, maybe we just need the EU/INTL version.
[Nexus 6P General] magooo:
The devices in some older videos with a dualsim tray and two IMEInumber-Stickers on the back are prototypes. I'm from germany and i will get my n6p in the next two weeks. DualSim is not common in europe rather in asia. But as i know asia and europe both will get the international version.
[Nexus 6P General] CarlJenkins:
For a desktop / home 3d printer it might be too fine of detail and too small of a part. Something like shapeways with a ultra detail material might do the trick.

I think the 6p is based on the same reference design as the huawei mate 8 which is about to drop at the same time. Maybe thatll have the sim card desired that could be ordered as a spare part.

---------- Post added at 04:22 PM ---------- Previous post was at 03:48 PM ----------

The honor 7 sim tray dimensions are 28mm by 21.5mm by 3mm l x w x t

Longer by a couple mm but might be worthwhile trying if the dual sim assembly matches

Aliexpress has that tray listed
[Nexus 6P General] irononreverse01:
Should be possible to print with a SLA 3d printer.
[Nexus 6P General] FuMMoD:
I have no access to a 3d printer but what I can see is if you mill it, you could possibly create another slot.
[Nexus 6P General] Rainstalk:
If someone works up a model I can print it.
[Nexus 6P General] matteventu:
Me too, I have a 3D printer accessible :)

My N6P should come in the next days...
[Nexus 6P General] Rainstalk:
I'll draw up some sketches soon and digitize them. Afterwhich i get a working prototype ill upload the designs.

Sent from a phone that isn't a Nexus 6p
[Nexus 6P General] jonmorris:
Glad I found this thread. I suspected dual SIM support from those prototype photos and the two IMEIs on stickers. Guess Google didn't want dual SIM support OR maybe will add it on an updated model in a few months.

It would certainly be a nice feature to add, and Huawei now produces most of its models in dual SIM variants, especially the Honor branded kit.
[Nexus 6P General] Rtistique:
Here is a good picture form ifixit. it does seem to have a dual slot but not the tray.
[Nexus 6P General] magooo:
o rly? close that thread! all question answered! :D
[Nexus 6P General] ern88:
My question is will the phone recognize dual sim cards?
[Nexus 6P General] FuMMoD:
We're hoping it's similar to the Moto x play which came hardware capable. The only thing they had to do was flash the rom for the dual sim version.
[Nexus 6P General] mazubo:
Subscribed! This thread is great, and I'm looking forward to the development of a dual sim ROM, to work with the hardware here. Awesome!
[Nexus 6P General] CarlJenkins:
Ive finished my model of the dual tray available for printing on shapeways

I don't think I have enough posts to upload the model here as an attachement at the moment but will if there is enough interest and if someone is willing to offer an sla print send to me as a trade for the upload

---------- Post added at 06:17 AM ---------- Previous post was at 06:12 AM ----------

If you look up nexus 6p on shapeways it should be the first result

I tried to take into all the chamfered edges in the design that were by design on the original sim tray

Broke out the handy digital measurement caliper for this
[Nexus 6P General] TonyHoyle:
Hmm.. Wouldn't mind trying this on the office 3d printer. Always wanted an excuse to use it..

Could you put the file on something like createthis.com for a small fee? Not much point in me printing it then paying shipping to the US.
[Nexus 6P General] wera750:
Hmm I might print one too. Got a .stl?
[Nexus 6P General] Rainstalk:
I'm sure we would be will (i would)to give you funds in exchange for its publication. I would like to print out a prototype a lot of work will need to be done before this thing is ready.
[Nexus 6P General] CarlJenkins:
Alrighty, I posted the design file .stl on github.com

If you search "Nexus 6P dualsim" it should be the only result. I'm releasing it under Creative Commons license CC BY-NC-AS 4.0

Please consider supporting the hours put in for the design work with my patreon page or by being the first hooking me up with a working print. Donation recommendation per asset download, patreon link and license details are on the github as well.

Feedback on 3D print results are encouraged and further design iterations, versions (for printer type and materials), adjustments should be easy to do or collaborate on now too.
[Nexus 6P General] magooo:
oh yeah ... this is the nexus spirit :D

like a bud bloom in the hand of the user
[Nexus 6P General] FuMMoD:
Do you have access to a 3D printer? I'm assuming no since you're asking for a working copy. Hopefully someone here with one can work in collaboration with you. I wonder how sturdy the model will come out.
[Nexus 6P General] CarlJenkins:
The 3D printer I have, realistically, can only print 150 microns (0.15mm) in abs or pla which is insufficient accuracy for this model. If you have one that does 50 microns you might be able to pull it off.

Looking at some of the sla printers out there they seem to be limited from 140 microns to .4 mm for some design details / layer thickness.

I found this service 3dhubs.com to outsource prints locally for anyone that needs to do that.

If you know how to cast bronze, brass or tin I'll post a castable wax option on the shapeways site additional to the high detail options.

If anyone might offer me a print for the design work done, almost like a trade, I'd greatly appreciate it.

I think software side if we could do a MOD similar to:

http://xdaforums.com/showthread.php?t=3002528

We could use stock roms from the Huawei Mate 8 and Huawei P9max for how to do it properly I think. Those are likely the closest in reference hardware design.
[Nexus 6P General] fodawim:
Oddly enough, after checking my phone (built on 10-29), it seems my sim card tray has the indentation to hold a second sim card correctly but still has the bar.
[Nexus 6P General] magooo:
wtf! google/huawei is watching us!

[MENTION=2021504]huawei[/MENTION]: can you please make a predeterminated breaking point in the bar in the next version? :D
[Nexus 6P General] atamkaan:
That shouldn't be hard to cut the bar off.
[Nexus 6P General] geoff5093:
I'd be curious if someone with the new SIM tray would take a dremel tool and just remove that bar and let us know how it works!
[Nexus 6P General] Win_Wizard:
Pease try this as i want to see if dual sim will work.
[Nexus 6P General] Slacker101:
Huh, I thought everyone's was like this (mine is) I was kind of wondering why you all were going through the trouble of printing them lol.
[Nexus 6P General] jpmadeira:
b a n.
[Nexus 6P General] designgears:
Had a few these made, should be receiving them soon.
[Nexus 6P General] FuMMoD:
Looking forward to an update! I would love to get my hands on a tray if possible.
[Nexus 6P General] jonmorris:
Surely it won't just work? I mean there are no menus for managing multiple SIM cards. Or am I missing something?
[Nexus 6P General] Steb6891:
You will have to load a duel sim rom
[Nexus 6P General] rbwsmith:
Where did you get them made?
[Nexus 6P General] geoff5093:
I've never used a dual-SIM phone before, is it possible you don't see any menu options unless it detects two SIMs?
[Nexus 6P General] jonmorris:
Not in my experience. Also, if it was that easy then someone would definitely be making alternative SIM trays and revealing the news to all.

As it stands, the need for a different ROM, and assuming it works even then, means most people won't be using it as a dual SIM phone.
[Nexus 6P General] Hunedit:
I can confirm that. I have a ZOPO ZP999 and if I just use it with one sim than the settings menu just show me one sim options. If I had two sim, its is appear two sim icon.

[IMG="One sim used"]http://logout.hu/dl/upc/2015-11/31316_screenshot_2015-11-14-16-44-50.thumb.jpg[/IMG] [IMG="Two sim used"]http://logout.hu/dl/upc/2015-11/31316_screenshot_2015-11-14-16-42-36.thumb.jpg[/IMG]
[Nexus 6P General] jonmorris:
Yes, but there's still a SIM management menu that isn't present on the 6P. I am not convinced that it's as easy as changing the SIM tray and it just activating. I think we'd have seen one of the major tech sites revealing that, and someone already selling SIM trays - as well as Google having been asked for a comment about why they weren't dual SIM in the first place.

Let's remember, there's no IMEI sticker for the second SIM. So that in itself might be a problem that has to be figured out. The prototype photos DID show two stickers, of course.
[Nexus 6P General] FuMMoD:
The major tech sites don't really innovate. Some independent group or person is always trying new things. We are that independent group working on the 6p dual sim. Once we succeed then all those tech sites you keep talking about will report it. For the second imei it can be set to 0 as it has been done in other devices with dual sim disabled. The sim management menu has been baked into stock Android since lollipop perhaps even earlier. There's been a lot added to this apk since lollipop. It doesn't just do simple sim stk stuff anymore.
[Nexus 6P General] jonmorris:
That's fine. I do hope it gets sorted as I'd love dual SIM functionality.

I would say I'm surprised nobody else has even reported this discussion. I first mentioned dual SIM in early September. I've also linked to this site more recently.

I suspect it is being monitored and at some point, if there's a break through, you're going to see the likes of the Verge breaking with an exclusive and trying to claim the credit.
[Nexus 6P General] FuMMoD:
Yeah they'll try but we already laid claim to it. I'm going to disect some dual sim roms and compare them to similar variants and see if there's any major overhaul. From what I've encountered it's just minor stuff and settings. The sim toolkit since lollipop has been managing the dual sim so it will run on all devices as to cause less problems with compatibility. What I'm hoping for is a minor addition to build prop like we did to enable multi window in marshmallow. It's in AOSP it just needs to be activated.
[Nexus 6P General] RED_:
Has anyone done a teardown of the phone to see what that extra slot does in the sim tray? If the metal was removed, or a new simtray with both slots open were used, would it suddenly just work? Would both sims get recognized, or will it do nothing because there are no connectors there? Would love the chance to have dual sim in this phone just with a new sim tray or other small tweak.
[Nexus 6P General] magooo:
Google added native dualsim support in 5.1 lollipop. So i think it's also included in 6.0 marshmallow. Menu and all we need should be already in the OS. But i don't know how to make it usable. I'm sure someone in this forum knows how to.

edit: i didn't see that there has been already page 13 in this thread when i wrote this :D
[Nexus 6P General] FuMMoD:
Have you bother reading any of this thread? All of that has been addressed already.
[Nexus 6P General] RED_:
No I haven't read 13 pages. Thanks for letting me know.
[Nexus 6P General] FuMMoD:
No worries that's all in there.
[Nexus 6P General] geoff5093:
He's agreeing with you lol
[Nexus 6P General] jonmorris:
Huh? Never said anyone was disagreeing with me?
[Nexus 6P General] RED_:
So anyone with a metal sim card tray able to take a dremel to theirs? First step is getting a sim in there, second step will be any software tweaks that are needed, if any.
[Nexus 6P General] CarlJenkins:
As per post #104 of the thread if default dualsim support doesn't bare fruit here are some sources for where to start on that front:

"I think software side if we could do a MOD similar to:

http://xdaforums.com/showthread.php?t=3002528

We could use stock roms from the Huawei Mate 8 and Huawei P9max for how to do it properly I think. Those are likely the closest in reference hardware design."
[Nexus 6P General] deeproot:
is their anyway that the dual sim spot is big enough to hold a micro sd card?
[Nexus 6P General] designgears:
no.
[Nexus 6P General] kilowatt95:
Great thread. I've been following it intensely ever since its inception.

However, one potential issue I haven't seen discussed in this thread is the second IMEI - yes, I'm aware that someone said that we could just change the IMEI to 0 in this case, but wouldn't that be illegal?
[Nexus 6P General] Rainstalk:
I don't think it is. I believe it is analogous to changing the MAC address (computer identification). People do this all the time. There are also IMEI changers AND IMEI cloners(cloning may be illegal). In this case we are doing neither. We are using a backdoor IMEI to access a network provider's service.

https://groups.google.com/forum/m/#!topic/misc.legal.moderated/2EpAdivJXBg
[Nexus 6P General] RED_:
I sent a message to iFixit in the hope they'll explore it, since they have the right tools, but otherwise maybe some sites like androidpolice would be willing to have a go? Only so much they can do before software tweaks may be needed but at least we can see some progress.
[Nexus 6P General] rbwsmith:
In addition to the 6p, I have a Galaxy S6, dual SIM. The lollipop firmware for the S6 I have (920F) is the same for the dual and single SIM models. As someone wrote earlier, Lollipop and Marshmallow are supposed to have native dual sim support. It seems he (or she) is correct.

My bet is if the 6p can recognize a second SIM, the firmware Will accommodate it.
[Nexus 6P General] jcsww:
I hope a viable dual SIM solution for the 6P comes available soon. RIght now, I am using a Nexus 6 and a Nexus 6P for the two phones I need to carry around. I would gladly retire the Nexus 6 if a reliable way for the 6P becomes available.
[Nexus 6P General] PaisanNYC:
Just ordered one using the template that was provided. It won't ship until "by Dec 1st", but I will definitely update you all when it arrives. I ordered one using the "Extreme high detail" printing, hoping it makes a difference for the better :)
[Nexus 6P General] morpheousrx:
This would be awsome...I'd use Verizon as one and Fi as the second...sweet
[Nexus 6P General] flyer_andy:
Hi, just a heads' up - adding the following line to build.prop (I'm using a Nexus 6 but I'm sure the 6P will be similar) makes visible the SIM Cards setting menu in the settings UI:

persist.radio.multisim.config=dsds

I'm sure there's much more to enabling dual SIM in the 6P than just this but at least it's something...I would be completely overwhelmed with joy if the 6P could be used as a dual SIM phone so I'm on pins and needles reading this thread!

Oh - one final thing...this build.prop mod does seem to mess up my N6's radio as it shows "No SIM Card" as the Carrier upon reboot...but of course switching build.prop back to the original version fixes everything back.
