Hi everyone,
I know this is an obscure one and I may be the only one who wants this sort of thing but I live in the mountains and like to use T-Mobile but also keep a Verizon (PagePlus) SIM on hand with a cheap plan as sometimes I have to enter T-Mobile roaming areas and need more data than is allotted for roaming use.
Anyway, I have a Verizon Moto X (XT1060) and a dual sim adapter which works awesome (i.e., I can switch back and forth between T-Mo and Verizon service without rebooting using the Sim ToolKit (STK) app, which pops up when the phone sees the dual sim adapter installed).
I've installed the dual sim adapter in my Nexus 6 (Play Store unlocked version) and while the Sim Toolkit does seem to pop up once the adapter is inserted (and the T-Mo SIM seems to work still - see attached screenshot) it then crashes when trying to switch between sims and disappears from the launcher altogether (you can try and resurrect it via a "Activity" in Nova Launcher but it still doesn't work and just says the app isn't installed). In doing some research it seems like the STK apps in AOSP ROMs don't work very well (which might explain why this scheme works well in the Moto X) but I was curious as to if anyone has had any experience with this problem.
Since the Nexus 6 has such unbelievable cellular radio support across pretty much any network, CDMA and GSM/LTE alike, it seems like it'd be a great platform for the use of a dual sim system, which is why I'm kind of surprised it wasn't a dual sim phone to begin with...expecially since Android 5.1 is allegedly adding dual sim support but I think that may be mostly just a GUI to facilitate switching more than anything else.
I'm running the May 14 Euphoria 1.1 (OFFICIAL-20150514) with baseband MDM9625_104446.01.02.98R. I've tried a the .95 baseband as well, to no avail...and rebooting after switching SIMs doesn't seem to work either (and neither does just "waiting" a minute or two). I've also tried the stock ROM and it doesn't seem to work either...same sorts of issues. Finally, I should concede this might work better with a GSM / GSM SIM situation as opposed to a GSM / CDMA/GSM situation so perhaps it's a lost cause.
So yeah I just thought I'd throw this up in case anybody had any ideas on how to make this work.
No idea how, but out of interest, which adapter have you got? I'd like one.

Hi! I got mine on Amazon...XDA won't allow me to post a URL but the name of the accessory is "LOPURS 2 in 1 (Dual SIM Card Multi-SIM Card + Tray Holder) for iPhone 5/5S/5C(Dark blue)." Even though it's for iPhones allegedly it does seem to work ok on the Android platform as well (at least, on my Moto X).
It's definitely weird looking but with a case around the Nexus it seems to fit alright.
Here's one for the Samsung Galaxy S5 on Amazon, but seems there's quite a few different ones to choose from:

Curious with the 5.1 update if this will work natively. It's been advertised that dual sim support is built into 5.1.
What's your experience? Any updates?

Unfortunately the adapter doesn't work with 5.1 or 5.0...one is able to launch the 'Sim Cards' activity (this gets you to the new SIM Cards settings menu in 5.1) via Nova Launcher by setting up an Activity widget but since (I think) the adapter can only work with one SIM at a time (it seems to block one or the other altogether depending on which is selected) the new functionality in 5.1 appears to not be useful in working with the adapter...I think it'll only work with phones that are dual-SIM by default.
I accidentally destroyed my last adapter (they're extremely delicate, and are hard to install with SIM tray-type phones) so I'll try this again once I get a new one using the Android M developer preview...fingers crossed!
Thanks for the update! 'Preciate it.
So...this can be marked resolved. It turns out that the Nexus 6 accepts the dual SIM adapter just fine (takes a reboot or two, but it eventually settles in and works great) and I successfully used it with two T-Mobile US SIM cards. The issue was the Verizon SIM containing some sort of CDMA code that was (I'm guessing) fouling up the changeover and crashing the adapter's firmware and/or the STK app. The odd thing is that it did work on my Moto X XT1060...but after trying again I noticed that voice support never actually worked on the Moto with the SIM adapter installed (nor did eHRPD or 1X data - only LTE worked) so it appears that CDMA just isn't compatible with the adapter(s) I've been using. I did see that MagicSIM offers an adapter that's allegedly compatible with CDMA but I'm a bit skeptical honestly and these adapters are just too delicate to spend $30-$40 on.
So, in conclusion, this functionality is absolutely do-able but it requires two GSM SIM cards as opposed to one GSM and one CDMA/LTE.
In any case it'd be totally awesome if LTE/CDMA-GSM changeovers could be accomplished with a different adapter...so if anybody ever has any luck with that please post! Thank you for the replies.

With the GSMx2 sims, how much functionality did you get? Could you receive calls on both numbers? Did you get a prompt when dialling which number to call from?
Unfortunately you only get very basic functionality. All the adapter is capable of is switching between the SIMs...once it's switched to one or the other it can only see that one SIM. You can set it to automatically switch back and forth in time intervals but I bet that can get really annoying sometimes if you're in the middle of a call or web browsing session or something...not sure if the adapter is smart enough to know not to interrupt a call or download with a switchover...I bet not!
I know that actual dual SIM phones can do what you describe but unfortunately none that I've been able to find have the vast frequency support of the Nexus 6 so it's kind of a conundrum...I really wish Google had made the Nexus a dual SIM setup...big missed opportunity IMO.
But in any case the adapter can help if you're a frequent traveller or have a work and personal phone or whatever and you don't wish to swap SIMs all the time...or if you're like me and just need two carriers to fill in each others' coverage gaps and can use Google Voice to route your main number to both carrier numbers.

That wouldn't be too bad I suppose as long as a reboot isn't required. I forward work to personal anyway and just turn work phone on when I need to make a call.

I have a work SIM and a private SIM and really do not want to carry two phones around. In my previous two models of regular (not-smart) phones I used one of those dualsim cards where you cut our the center of each sim and slip them into a new sim card with some extra electronics on it. You can then switch between the sims with a couple of key presses or even at automatic time intervals. eg. http://duosim.com/
OK, so I have two different makes of this type of dual-sim card and tried each one in the 750. The switching program shows up in the phones menu and it looks like it is going to work but it does not. When you try to switch to the second sim, the phone switches off and back on, but the the phone is still using the first sim.
I really want to find a way to get this to work. I have ordered one of those multi-sim card cloners (same link as above), in the hope that will work differently.
Has anyone found a solution to this ? Either a particular make of dual-sim or multi-sim cloner that works or maybe a tweak to get past the above mentioned problem ?

Hi gajsler,
I found myself being in the same situation: Want to use both office and private Sims with my Treo.
After some research I can say that it depends mostly on the combination of SIMs you are using. If you are using any UMTS/3G SIMs then a digital DualSim-application wouldn't do trick, especially if you are using a H3G-SIM (Hutchison 3G).
You will need an analog DualSim-holder for these SIMs.
I've got one from HongKong (Ghost SIM, no cutting) but it doesn't work correctly. Only the first SIM card is being used ... don't know how to get past this issue.
Seems to be tricky. Will post any additional experiences.
Greetz,
TreMax

I'm using Simore Gold 2 and it works perpect.
http://www.simore.ch/en/mobile_phone_accessory/HTC/P4550.html
any1 tested?
I want too, but i want to be sure the today plugin is working correctly
Also if you are roaming, will it switch automaticly ? Or do you need to manually switch provider?
wow that looks pretty good...
i am really interested too....
i think it switches automaticly.
anybody?? this sound really good
Word of advice, while I've been investigating various dual/multi-SIM solutions available on the net, it's become apparant that many of these are quite "fishy". I.e. they don't work as advertised. A lot of issues especially with the newer 3G-SIMs. When it comes down to Simone, they are incredibly expensive and also get quite some pepper on various forums. Don't be fooled by a fancy website
If you absolutely do want to test out a dual-sim solution its probably better to risk a way cheaper solution from e-bay as it seems its mostly the same one or two producers behind most of these products, just sold by many different people/resellers.

i have used the dual sim adapter without succes. it seems that cutting the original sims has to be done very acurate which i did but no results. Also a lot of pressure has to be aplied on the sims/apapter for good contact otherwise it would work.
may be in near futere i would like to try a non-cut version.
cheers, Steven
There is another way to do this : instead of inserting two, cut, sim cards, you just insert one sim card but programmed with two different sim cards.
I made a thread about this, I just wanted to know if anyone had experience in that : http://forum.xda-developers.com/showthread.php?t=349410
This sim card programmer can be found here :
http://www.duosim.com/supersim.html
As it's not very expensive, it could be interesting to test it.

The problem with this thing is that it cannot backup the newer SIMs. I tried this with my Cingular 3GSM SIM and it would not work. It only works with older SIMS. So if you have two older SIMs you could be in business.

I am using Simore card in my Kaiser for 2 months now...
FYI, Simore cards do not support 3G protocols: I had problems with it (freezes, no access to 3G or 3G+) and phoned Simore company and they confirmed it. I can only use Edge as the best protocol available for data.
For avoiding any problem of freezing, you need to set in the "band" index of the phone parameter menu the type of network you use (GSM or CDMA) instead of leaving the default "automatic" choice. You can leave "auto" for "GSM /UMTS" Band parameter (even though Simore told me to set the first choice: "GSM (900+1800)+UMTS (2100)"...)

This is true. It is not yet possible to copy a 3g sim. Someday the code in the sim will be cracked though.

Hi there,
would like to ask you several quick questions:
1. are you mounting two GSM SIM-cards on your SIMore?
2. are you using "SIMore Gold #1" model for the adapter?
please advise (laubet / anyone that has tried it before).
thanks for the reply.
kaiser wrking with gold simore 1
I finall figured out how to get this dual sim card to work. You need to first manually switch the network. For me its T-mobile and AT+T. Once you manually choose the network, then use the sim program to choose the appropriate sim card. For some reason automatic selection of network does not work. Any other way hangs card, or makes network unavailable.
Hi,
Tried using the search function here but nothing came up in the X1 forums. I have been thinking about getting the X1 but given my normal needs, I need access to two numbers during the day.
Is anyone already using a dual sim adapter (cut or uncut version) or knows of a reliable one for the X1?
Thank
Hi
I just ordered one the other day. When I get it i'll report if its any good or not!

How do you plug it?
You must remove the battery cover.
Hi
I think its the usual "saw up your sim cards" job, then fit the important bits into a holder thats the same size as a normal sim, then stick this in the sim slot.
For the most part switching between sims involves powering off/on the phone. I did have one in the distant past that would swap sims when you set it to flight mode then back out again.
We shall see, it was only £6 quid iirc.

The dual sims also have phone numbers to switch sim.
Ps. could you share link. I also wanna buy a good one.
please tell us of the HSDPA works with the dial sim card thing because most of the time only 3G is supported
Any news?????
So what happened?
Anyone know if there are adaptors which will always use one SIM card unless told otherwise (rather than switch when power-off)? Ta.
i guess no updates on this but i did see this:

Do dual sims work in the X1?
I'm using the dualsim adapter of simore in my xperia
switching from sim1 (vodafone) to sim2 (simyo/eplus) works realy fine - it durate max 15 seconds
but switching back to sim1 making sometimes trouble...so that i has to softreset the phone
i dont know if that is a global problem with the xperia and the simore adapter or if somethin is damaged in the simcards/adapter?!
additional i have to change the sms service number after changing the simcards...
has someone problems with that too? or a better solution?
sorry for bad english O
Simore
Yeh, Simore are meant to be the best, I was looking to get one also but for the good Simore one you are looking at paying 70euros which is far too much.
Unfortunately, the design of the Xperia means it is only possible to use Sim Adapters that chop the sim card to pieces and fit them in the size of 1 sim.
Edit: http://www.simore.ch/en/mobile_phone_accessory/Sony-Ericsson/Xperia-X1.html
Curious to know if that works on Kaiser. They are charging exorbitantly high. wish to know if there are any other reliable agencies offering same service. Cheers.
I ordered few different models from eBay but either of them didint work. If someone succeeds on this please report.
I had an older dual-SIM adaptor that I've been using for the last couple of years. I tried it in the X1 and it worked okay (flight mode to switch). The problem was that it didn't support any 3G at all, so in a 3G area it was constantly attempting to get a 3G lock, dropping the signal, then trying to get a lock again. In the end I had to disable HSDPA.
Then I got a new SIM from O2. I just put the SIM in directly without the adaptor. BLAM! Better signal and HSDPA access. So I've been on the lookout for another adaptor that still allows for switching but supports HSDPA. I keep ending up at simore.ch as well and wonder if their "Black 1" is up to the task. I don't want to pay out €40 just to see if it works though... I need to hear from someone else who has bought one and used it for HSDPA access.
So the question is who will bell the cat. None of us are eager to try it out. So would like someone with his experience to come over here & let others know if it was a success or not. I am interested in kaiser utility.Cheers
i have to disable hsdpa and umts while using my simore black1 adapter...if hsdpa is enabled the connection always broke down
it show the symbol that the signal is good and after 30-60seconds my xperia search for signal...endlessly...
i dont know if that is a problem with one of my sims (but without the sim adapter they both connect to hsdpa) or if that is a problem of simore
i think the last one
It's the sim adaptor.
My old one does EXACTLY the same thing. It attempts to get a H or 3G lock, then loses the signal and recycles back again. It sounds like simore are just the same as the £6 one that I got from eBay 2-3 years ago.
I just cannot understand why it's so problematic to build a sort of cartridge (like those dual-SIM adapters) with two EEPROM of Flash elements inside and sell it together with a USB SIM reader-writer?
So any basic user could copy his/her two SIMs to this cartridge and skip all the mess with improper cutting and loosing two SIMs?
AFAIK any SIM could be fully read. Why it cannot be simply copied?
I've got very cheap dual sim adaptor (11th generation) and it fully works in new itje's ROM. I also copied STK from this ROM to memory card and tried it in older itje's ROM Touck-It 4.0 RC1.1 I could connect to internet via HSDPA and simply switch SIMs, so you don't need too expensive SIMORE adaptor.
Edit: I have tested internet connection short time and I didn't have signal lost, I'm out of credit right now but I will report more after I'll top-up and do more tests.
(sorry for my poor english)
Well, here I go again with not only another smartphone but I finally got my hands on the GT-N7000 International model with the physical home button. So I get it home, check it out, everything appears to be working fine:
- battery is brand new, just manufactured in January 2014, not a fake one (I checked that out with Samsung directly based on the battery serial number)
- was originally on Android 2.3.6 and upgraded to 4.1.2 through Kies without issues
- no hardware problems noted, everything works great, no damage to the phone at all
Here's where it gets a bit confusing. This is the International version which means it should be unlocked without me having to do anything to or with it, so - when the phone was on 2.3.6 - I took one of my newer T-Mobile microSIM cards and using the adapter to make it a proper miniSIM I slid it into the SIM slot, put the battery back in the phone and turned it on, and nothing gets detected at all.
I pull the battery, find another microSIM, do it again, still the same result. In fact, every microSIM I have (4 T-Mobile, 1 AT&T, all within a year old but none of them are currently activated - whenever I use the T-Mobile SIMs it will still connect to T-Mobile and allow me to pull up the billing web page; the AT&T SIMs never do that and just complain about the SIM not being provisioned).
Since my intention is to use the $30/monthly plan with T-Mobile that I've had in the recent past, I went looking into my little canister of older full size miniSIM cards and found two of them that I used with T-Mobile over the past few years. As most devices use microSIMs and even nanoSIMs nowadays, I figured I better keep them around just in case.
SO... I put one of them in and voila, I get a connection - or so I thought. When inserted, and again when using 2.3.6 I was able to get into the service menu (*#*#4636#*#*) and it would show the number assigned to that SIM originally, etc but it wouldn't show the network. Tried the second SIM card, it gets recognized, same thing - it just doesn't show T-Mobile.
Now, I've never had an International Galaxy Note so I'm kinda confuzzled here so the primary question is this:
Is the GT-N7000 simply incompatible with some SIM cards, even when they're in an adapter so they fit into the SIM slot proper? I know this isn't an LTE capable phone, that's not a concern at all - I suppose I'm not 100% sure that it's even compatible with T-Mobile given the bands but since T-Mobile works nicely here in Las Vegas (at least for me) and they're using more bands nowadays, I'm very interested in attempting to figure this out.
I went ahead and performed the Kies upgrade to 4.1.2 and it's working great so far, but again the same issue: the phone can't or won't see or access anything but these two older T-Mobile miniSIM cards - not anything else that I happen to have which includes two brand new T-Mobile microSIMs I ordered a few weeks back.
Could it be that perhaps the leaf-spring contacts inside the SIM slot are just not making contact on some of the other SIM cards that I'm trying to get recognized, or could this be something with the phone itself due to it being the International variant, or maybe it just not supporting the bands that T-Mobile happens to be using nowadays...?
Any help or info is greatly appreciated as I'd really love to get this thing up and running. If it means I have to get yet another SIM card from T-Mobile to get it working then that's what I'll have to do I suppose.
Thanks for any input...
ps
Just for the record I popped the back housing (not the battery cover, I mean the back housing held down by screws) off just now to get a look at the SIM card slot itself, it appears to have a 3-2 configuration (meaning the 3 visible leaf-spring connectors and the other two are not visible unless you remove that back housing). Maybe a lead snapped off, perhaps? Seems like there should be 6 leaf-spring leads...
pss
And after looking at parts on eBay it does seem like there should be 6, I guess one of them snapped off at some point with the previous owner and probably the reason they were selling it. Odd...
I am contemplating purchase of one of these phones, and tried entering some of their IMEI numbers in the imei checker at https://www.t-mobile.com/resources/bring-your-own-phone , and was shocked to find they are ALL described as "Incompatible".
This is a bit confusing after the articles saying the AT&T and Verizon versions would not work after Jan 2021 but that the T-Mobile version would continue working. I tried looking for a later article saying that support for the T-Mobile version this model was being cancelled but could not find any such announcement.
Is that IMEI checker correct? Or is it because the samples I checked may not have gotten the last modem update installed from T-Mobile?
Is anyone still using this phone (specifically the T variant) on T-Mobile in USA? I'm assuming that last update will be important, but does this still work once it is installed?
If yes to the above, do phone calls work as VoLTE, or is it doing the fallback to 2G?
I've also seen threads about enabling more LTE bands, has anyone done that on this phone? In particular is it possible to add support for B71 (600MHz), or is this radio hardware just too old to allow that?
Thanks much, I would really like to know whether I can use this phone or if I would need to find a different model.

SM-N910T with 2ETI1 OTA modem update works fine. 4g/LTE Data, WiFi Calling works. Does not drop out of 4G/LTE for voice. SM-N910V w/ MODestROM v11 (6.01 TW-based N910VVRU2CQI2 ) w/ a vzw 2CTI baseband update, has working 4gLTE data, but no WiFi Calling, or VoLTE (falls back to 2g, but I still have 2g coverage here, so it's usable, if not optimum. Here's the thing: on the VZW phone, if I set the the salescode to TMB, suddenly VoLTE works, but the Setup pages/menus/statusbar are screwed up, so it's not really useable. Here's where it gets REAL interesteing. On a VZW phone w/ VZW 2CTI1 baseband, & VZW BL, flashed with a custom TMB ROM (trltetmo_N910TUVU2EQI2_Stock_Deodexed, debloated, but still TW), EVERYTHING works. But it's not stable, it periodically loses 4g/lte. What it tells me is that the VZW h/w is NOT THE PROBLEM. I've been at this all day, everyday since VZW turned off CDMA on 01/01/23 and killed my service here. Be warned: If you go down this path, you're gonna be mostly on your own. A LOT of dead links, 'retired' devs, etc. Everyone except you, me, and three other people here have long since moved on from this awesome phone. I'll help you if I can. I bought an SM-N910T , but the damn usb port is dead. Already changed the charging board, not the problem. It's the mobo. If I could identify the usb chip (if it's not the 805 itself, I'd change it. So I have a phone with no adb that I can't unlock/root. I'd much rather get my VZW phone fully working on TMB, since I'm heavily invested in the MODestROM. Haven't given up yet. But search my posts, you'll hear the deafening silence, lol.
Seeing this forum has so little activity, on 1/21 I ended up getting a used Moto E6 (XT-2005-3 is a tmobile aka carrier unlocked MetroPCS version). While overall this is not as nice a device and has fewer features than Note 4, it does cover what for me are the essentials - removable battery, SD card slot, support for 5.8GHz wifi. Best of all, it supports B71 which will be helpful for, well, making phone calls!
I still ponder someday getting one of these as a hobby device, but that would be second place to the E6 for use as a phone, and won't be for a couple more months yet (too many expensive household issues are taking their toll on my "toy" budget right now).

SM-N910T with 2ETI1 OTA modem update works fine. 4g/LTE Data, WiFi Calling works. Does not drop out of 4G/LTE for voice.

Thank you, this was the part I needed to find out. With that in place, the only thing missing would be the B71 coverage but the E6 is already in place for that.
Re your Verizon adventures, I have no experience with any of that. What I read about T-Mobile dropping support for the verizon version in the last network update is all I know, and I don't have the skills to dispute what they say there. The best I could do is offer some links to threads on this forum but on double checking them it seems you've already been there and got no answers.
The only thing I see that might help you with that is if you could update just the t-mobile modem without disturbing the verizon bootloader. I see you tried that but it didn't stick when using Odin. I don't know if it would be any different using SmartSwitch that seemed to work for MarineWonder as he posted at https://forum.xda-developers.com/t/...pgrade-on-jan-29th-2021.4224237/post-87464609 ?
Then again he may have been putting it on a t-mobile phone rather than mixing with the verizon bootloader so who knows?
My guess since it has been so problematic for you on the verizon phone is that you may need to only use a tmobile phone since that may be the only way to get the last t-mobile modem update. Bummer that the one you bought has a dead usb port. How are you charging it? Is there any chance you could return it to the seller since it came pre-broken? Then put the refund money toward another, hopefully working, tmobile phone? And would that MODestROM work on a non-verizon phone?
The only other thought I had is there are apps to connect to ADB over wifi. Sadly most of these need root. The ones that don't, seem to need at least once using a usb connection to do the "adb tcpip 5555" command to set it all up. . . . how annoying that it is all so circular!
There is also https://telnetd.en.aptoide.com/app?store_name=apps&app_id=59202144 , maybe a telnet connection could do the "adb tcpip 5555" command instead of using the USB connection? Sadly the documentation (at https://waxrain.com/docs/010.html ) appears to be written in Chinese, and I never had much luck with google translate.
The N910T still supports VoLte.. It is still compatible with cellular networks.
