single vs. dual SIM - Moto Z Play Questions & Answers

i got a Mot Z Play from Amazon.de.
Unfortunately it is a "single"-SIM version. Is it possible to get DUAL-SIM functionality applying a specific firmware? Or is it hardware dependend, too. The SIM-slider has a glued dummy which can be removed.

I would say it' the same then the X play. Maybe you need only remove the glue

I removed the plastic thing on mine and installed a sim on there, my phone did nothing. I'm almost sure its just firmware, if you look down in the hole theres pins for both sims

Also would like to know whether it's HW limitation or SW(like the moto x play), I'm using a dual sim phone so this is a must for me.

sorry for over topic
is "single sim" xplay from amazon can make 2nd sim work by flashing ds firmware?
thanks

Yes it's been proven and done by many people, just search in the Moto X Play forum. This is the Moto Z Play forum.

Where did you put the 2nd sim in? In the micro SD slot?

If you have a dual SIM version, then obviously you put it in the 2nd SIM slot.
If you have a single sim version, there is nothing you can do right now to use 2nd SIM. There might be a way in the future to convert single SIM version to dual SIM by flashing dual SIM ROM, but that's not guaranteed. If it's possible, you also need to remove the plastic that's blocking the 2nd SIM slot.

Or I'm sure someone will make cyanogenmod for the z play and enable dual sim

It's not just a software thing, for this to work, the hardware needs to have an IMEI for the 2nd SIM slot (but 2nd SIM slot is disabled in the ROM and also physically blocked by the plastic). If the phone doesn't have a 2nd IMEI, it won't work regardless of what you do with the software.

What would that mean? A dual sim firmware would enable a 2nd imei? Other than that you can let the sim part print by a 3d printer there are shops in my town which do that

A Dual SIM firmware will not enable a 2nd IMEI, IMEI is assigned to the hardware, there is nothing you can do in software that can add an IMEI. If 2nd IMEI is not present the firmware will see it as all zeros, and most likely cannot use the 2nd SIM, A Dual SIM firmware will allow you to use the 2nd SIM slot IF there is a 2nd IMEI.
I"m not sure what you mean by your second sentence, what's a SIM part?

I mean that you could let a 3d printer create a sim tray with a hole for the second sim

You definitely can, but it's probably easier and definitely cheaper to remove that piece of plastic. A lot of people have done it.

That you cannot change or assign an IMEI is just not true. It´s not legal and so on but there are Xposed modules that let you do it for example. With MTK-Devices it would even be just an command in engineers mode, for wich you don´t even need root (Done that many times). With Qualcomm devices its a bit more difficult, but still managable (step-by-steps can be found via Google)

There is so much wrong with this post, I don't even know where to start.
"It´s not legal" - if something is legal or illegal is always based on your jurisdiction. The vast amount of countries and states have no law against modifying one's IMEI. Hence, there is absolutely nothing "illegal" about it. There are a few notable exceptions, those are mostly the countries that won't let you use a device with a blank IMEI in the first place (like the UK).
"there are Xposed modules that let you do it for example"
Please, point us to one that works with a current or even semi-current Qualcomm SoC. Given that the IMEI is controlled by the baseband it sounds exceptionally unlikely that they actually change the IMEI that is broadcast to the cellular provider.
"With Qualcomm devices its a bit more difficult, but still managable"
Again, please give us a source for such instructions for a current or even semi-current Qualcomm SoC.
There is a reason why nobody ever found a way to change the IMEI on the X series dual sim mods. This is unlikely to change with the new Z series.

Hi,
okay, i´ll be honest with you: I havn´t done that on any Qualcomm device since maybe 2 years. Maybe you are right, maybe not. After about 15 sec Google-work I found many posts like this one:
http://www.androidbrick.com/ultimat...agon-xiaomi-mi5-imei-and-baseband-repair-fix/
They are talking about the 820, so I guess thats "current" enough Might be, that Lenovo did some stuff to prevent this, but obviously its not totally false to assume, that with some (most, many) Qualcomm devices you can still get/change the IMEI.
Sure there are always exeptions from the rule (with Gionee M5 Plus I wasn´t even be able to enter fastboot lol), but to say, that an IMEI is assigned to the hardware is at least as false as my - maybe to hasty submitted - reply.
About the "legal"-thingy: Yeah, sorry for not thinking about that. All regions I ever where it was illegal (UK, GER etc). But I guess, thats not to important here

No SIM insterted, advices please

Hy guys,
I have a situation and need some advices
I have the opportunity to buy NOTE2 for a very fair price, BUT device cant read a sim card :-S (with sim card inserted)
Device does not have a waranty (because it is bought out of my country, to be specific it is from austria), and seller said he is not take it to a service center. so there is no diagnosis what is wrong with it.
I have not seen the device yet, but i will see it in about two days. Seller said that the device is almost new, and it is fully functional except the sim card.
I was ask him is maybe sim slot is broken (people cut regular sim card, and stuff), he said no (he also not sure, because he exchanged it for something else etc).
But nevermind, I will see if it is hardware problem (lets say that I am experienced in this ). I would like to see broken sim card slot, because it is replacable . But lets get to the part where I need advices. possible software problems
I read through forum, and there is various problems and solutions, and also there are few with no solution
I need help with my check list:
1: I will check the IMEI. If there is no one, I will give up
2: If there is IMEI, lets say that there is a chance (maybe someone flash a different rom etc). My qouestion is: Will I be able to make a proper backup of EFS? ,Then try to flash different, modem, kernel, rescue rom, etc... Without a chance to loose IMEI? (properly getting back with efs backup)
3: I read that there are few guys who bought a retail version of the note (the one without radio chip at all). Is there a way to recognize such? (i dont remmember if this version have imei, or not)
4: Is there a chance that device is only locked. What message appear in that situation (no sim, wrong sim, type unlock code or something similar ?)
5: What are the chances that maybe the radio chip is blown , If we assume that the device is relatively new and not dissasembled or something (I know that this is hard to recognize, but maybe, some services code or something)
6: Is there a some kind of service mode to check if the radio chip is functional
So to conclude: If you guys can help me with the check list, feel free to add tips.
I am sorry for this long post.
Thanks in advance
wow, posted a question last nigh, and now it is on a third page lol
lets bump
So once again, my main question is: Is there some service code/mode to check whether the radio chip is functional/or whether is the radio chip existing in a device?
the rest I will leave to chance
again, thanks in advance
Go to a your local telephony service provider, give them the phone's IMEI and inquire about it if it has been black listed. If your device's IMEI has been blacklisted IDK if there's a tool to clone/change it to a newer one. Once the device's IMEI has been blocked, that process is irrevocable unless the previous owner clears the issue for you.
Blocking IMEI happens usually to phones with unsettled payments for the phone unit.

Thank you, that is sound intersting, and when I've thought about it can be possible cause.
This device came from Austiria to my country, so If we assume that the IMEI is black listed; Whether this can be checked by any carier/service provider? or just one where phone is bought?
thanks again
if it is carrier locked then you should still able to dial emergency number isn't?
in hardware issue you can't.

Just like what dr.ketan said(which is the easiest way to troubleshoot it), try dialing the emergency number wait for the ring(a single ring, then put it down - don't try to call again if it does ring) and if someone answers your call - say the matter has been solved. The phone is network locked.
Thanks guys, I was reading a lot through forum, and my head is full of ...:laugh: so I overlooked the logical solution
Thanks again, will try check phone maybe tomorow, and I will let you know

Is it possible to use two SIMs on a single SIM S9+

Evil Samsung does not sell dual sim models in Australia... Is there a way to use two sims in their single sim phones? Was this ever possible with S7 and S8 phones?
I have an international model S7 edge but decided to get an Australian S9+ because they receive better service and support here, well, actually I broke the screen of that S7 edge, again, and the repairing cost by a 3rd party just made it pointless, all because Samsung Australia won't repair it for me (for a more reasonable A$210) for it is an international model (UAE).
If this is technically possible, best case scenario I just need to find a correct SIM tray?
You can use two different SIMs if the phone is not locked to a particular network.
However, if the phone is not Dual SIM, you will not manage to use both cards at the same time.

So you are saying the hardware is there, but the software won't allow me to use both SIMs at the same time?
I take it as flashing dual SIM ROM would not only void warranty, but beats the purpose of buying an authentic local market device in the first place?

No, what I mean is that you can use two SIM by switching them and having only one at a time inserted in the phone.
If the phone is not dual SIM, you can have two SIM cards working on it only if the phone is a Hybrid Dual SIM.
If the phone is SINGLE SIM, you can't do anything about it.
Hope that this answers your question.

yeah there are 2 versions, if you picked up from a network chances are it is a single SIM variant, if you purchased unlocked through the likes of Samsung it will have "DS" on the end of the model number meaning it is a dual SIM variant.
it's confusing but it's just the way it works unfortunately as it cuts cost on network provided phones.
basically if you want dual SIM your best bet is to purchased direct from Samsung or a third party who sells the dual SIM version, but a network provider is likely to give the single SIM to stop people using 2 networks and to cut the cost of a second modem.
So there is no way to mod or activate the dual sim in the SM-N975F (without DS) model? Is it hardware limitation?
If I remember correctly the single sim Note 9 did have a mod for this.

There is no 2nd SIM to activate on your phone, it is physically lacking the hardware to support a 2nd SIM:
SM-N975F : Single SIM
SM-N975FD or SM-N975F D/S : Dual SIM
If you want to eliminate all doubt as to whether your phone indeed does have a physical 2nd SIM, the only other possibility that I can think of is if you buy a Dual-SIM Card Tray & flash a (compatible?) Dual SIM firmware, but, doing so at your own risk.
As others have stated, the carrier branded versions are Single SIM & in all likelihood, are not capable of being converted to a Dual-SIM model.
The firmware for N975F and N975FD is the same, there is no specific FW for dual SIM.

Thx for clarifying that firmware for both is same. My phone specs shows that model is SM-N975F but it is dual sim and it does not show anywhere that it is SM-N975F/DS or SD.
Why it is like that. Is there something wrong or just becoz they both have same firmware so it just shows N975F.
Nothing wrong, I think only the box showed that it was DS.
Mine also N975F/DS, but does not show on outside phone nor in phone info in settings.
It does show 2 IMEI-nrs both on outside/back of phone as in phone info, that's the giveaway!
Hi you can convert a single sim note 10+ to dual sim, it does have the hardware as does the s10+ I have done it to both. Once you have activated and tricked system into thinking its a factory dual sim device. you have to write another imei to the second sim other it will be 000000000+ but But thats easy to do using any number of commercial tools i used chimera tool

IMEI numbers are assigned to a specific logic card serial number, anybody assigning an imei
Number the way you point out, is performing an illegal action
Does somebody make it works?
See on the box it's written
SM-N975F
ON THE QUICK START GUIDE ITS written SM-N9750
ONLINE when I search the IMEI it's written SM-N9750
INSIDE THE DEVICE ITS SELF AT ABOUT
ITS WRITTEN SM-N975F/DS please I'm confused. Is this phone 2 SIM , is it 5G also when I on it, it shows 5g but I can't find the network inside the phone
It came with a single SIM tray and slot two IMEI shows all zeros

Question Single to dual SIM possible?

Is it possible to convert network locked single SIM models to dual SIM?
im not familiar with this, but how does that even work? There's only 1 sim slot on the single sim version, and only 2 on the dual sim version. I guess you might be able to get some sort of modification or adapter board to connect for dual sim, but that would be a bit janky wouldnt it?

It has a single slot in the SIM tray, yes, but I hoping the internal hardware might be the same as a dual SIM model. That might be unrealistic as I can't find a region that offers both dual SIM and NFC. What I do know is that it is possible to convert at least some Oppo models from single to dual SIM by changing the region and flashing other firmware and of course replacing the SIM tray. After that, it works like a bought one.
just sell yours and buy a dual sim model, why go through all this trouble?
it will probably cost the same, if not a little bit more, but it would be a genuine dual sim model.
most dual sim budget phones dont have nfc anyways.
i dont know any other information, so sorry for not being much of a help
Yes the phone is dual Sim variant , just need to buy dual Sim card tray or if inpatient, and a steady hand, just cut the Sim card holder for second Sim out.

Sorry if this is a dumb question, but why the heck would they cover up a second sim slot if available? Isn't a second sim slot better for their marketing of the device? Wouldn't the device show up as dual sim in the about phone section of settings, despite only having one usabale slot? It doesn't sound like a smart thing to do.
They're also wasting that "precious" in-phone space, not to mention the manufacturing costs to make a dual sim model (which is single sim), only to sell it for the same or less than an actual dual sim model with a usable second sim slot.
Usually what they do is they remove the second slot to make room for the nfc module. That's why you don't often see dual sim phones with nfc in the budget/mid range, it's either one or the other.
Mate, completely agree, but you need to ask mtk/Oppo/realme
The only explanation I can think is, that in Australia, it is extremely rare to be able to buy dual Sim straight off the shelf, usually havego order in(from my experience abut that could also just be Sony phones as well) only my second realme and the C3 that I had before this phone was exactly same
Again, question needs to be asked off manufactures lol
I can only tell you what is and what can be done, as I modified the Sim card tray as stated and put Sim In and there you go.
Wow. I thought that they might disable dual sim since the model is a "single sim" one, despite it having the hardware capabilities.
It is disabled in Australian firmware. That is not surprising for a carrier locked model for obvious reasons but what is somewhat surprising is that the carrier unlocked Australian version which seems to be only sold online direct from realme is also the same model at the same RRP. I think it might be realme's only single SIM model sold in AU. I suspect you might lose NFC if you install dual SIM firmware on it but smiley.raver would know for sure.
I can only speculate that since Australia is a relatively small market it is not worth the effort of manufacturing a special hardware variant for it. OTOH, if that is true that suggests the model might have latent NFC characteristics in other markets which seems a bit of a stretch, so it maybe that it is harder to subtract the 2nd SIM contacts than add NFC. TBH, for such a low power CPU its a bit surprising to see NFC anyway but Optus would only care about the end result for the cheapest cost and maybe the different firmware and modified SIM tray is the cheapest manufacturing option.
As attached. Wish I had some spare tags lying around to show working but screenshot is best J can do lol
What combo of region and firmware are you using or other magic? It's interesting that the firmware you are using has auto-detected either the 2nd SIM or NFC when that combination is not sold in any region.

Also interested in knowing how to use a second Sim. Out of curiosity I modified the Sim tray, but the 2nd Sim was not detected. Android 11, rmx3201AU_11_C.09
If you search the Oppo threads you can find the odd guide on changing the region for example this thread I don't know whether that is sufficient and if its is whether the mix of Australian firmware and different region causes a problem with future updates. I'm lead to believe that changing the region via the process in the linked thread is not possible with Android 11 or at least after some particular update on Android 11. If changing the firmware is required I don't know whether there is a suitable image that will flash itself but there are programs that will do that e.g. mtkclient.
Hopefully, smiley.raver will comes back and provide some more pointers or maybe you will if you're braver and less patient than me.
Good luck!

Just an update, phone automatically updated with rmx3201_11_C.11 but still only detects one Sim.
It won't happen by itself. You need to change the region code and/or install firmware from another region to have the 2nd SIM detected. If you need to rollback to Android 10 so you can change the region code there is a link to a rollback package in the post introducing realme UI 2.0 / Android 11 on the (Indian) realme community site. If you can't find it let me know and I'll have a look later.
Yes you will need to roll back to adtod 10, to change region for firmware, as I said in running Australia Optus prepaid region and I get the updates as well as the dual Sim and nfc(if you need a quick way to test of nfc works use a bank card with a chip on it , turn nfc on and putghw card near the phone, phone will either do nothing or say no process to view the data or something along those lines which means it has recognised a nfc device near it.
I'm not sure I was able to parse that properly. Which region did you change to? Are you saying that you didn't reflash the Optus firmware and continue to receive updates?
Just used the region changing method, selected the Australia Optus prepaid, , phone restarts no data lost.
Done on 2 c21 phones, both have working nfc and 2nd Sim.
I will back up my other 'testing' c21 and try make short video to show it all working,
Region changing in android 11 requires god like access it seems to access that same section, there is probably a way to do it. But just easier to roll back to android 10, change region, reflash you backup, then wipe (this is only if already upgraded to 11, that there is a data loss) mdc, usereata, metadata and then you will be on working android 11, dual Sim, and nfc
I will see if I can find an old sim card, and uploaded short video with both those features working, the 2 c21 phones I have were also brought from different supply chains as well

Don't do a video just for me. I never watch them, but I wouldn't mind reading your comments on one of the existing guides about any gotchas or steps that can be eliminated. I don't really understand what the software is doing apart from enabling the region change and possibly other codes. Would be good if there was an open source version of the tool.
BTW, according to a post on OzBargain there seem to be 2 versions or perhaps production runs of the Optus C21. The later one has a screen protector applied and there is no carrier lock. Looks like even the one realme sells directly is also (Optus?) locked as their web site changed recently to state they woud supply an unlock code with the phone.

Question Does the T-Mobile version have dual-sim capabilities ?

Can anyone confirm that they have the le2127 model and was able to get dual sim working even after flashing it to the global ROM ?
I just went through all of the steps and converted my le2127 t-mobile version of the 9 pro, only to find out that there is no dual sim functionality. All of the other older OP phones have it.
I do see the pins in there for 2 sim cards but I can't get it to work.

Also, when I check the IMEI's using *#06# only one imei is shown. At one point during the updates, to android 12 especially, two empty sim slots did show up but, both had the same IMEI #. Upgraded to 13 and now only one IMEI. I do see pins in there for dual sims so this is a very confusing phone out of the 4 Oneplus phones I own.
So I need to get this figured out before my return window closes.
On the box your phone came in, how many IMEI codes are shown?

Ok no worries
You've more than likely thought of the below, however if you haven't
Possible approaches to find both IMEI numbers
Does the tmo variant actually have 2 imei numbers?
Did you backup any of your phone before modifying?
What info did you have to submit to tmo, so that you could unlock the bootloader.
The vendor you bought it from, if official may have a record of your imei numbers
Have you used Sims on both slots of the phone? If so your Telco will have a record of the IMEI against the call.
There maybe a simplified approach, I'm sure someone else may also be able to help
Did you get it with any paperwork?
Was there an imei sticker on the back of the phone?

I guess to sum it up now with those questions. I do remember that when I applied for the unlock.bin I had to provide the IMEI number(s). And I remember there only being one through *#06#. Plus the sticker that was on the back, which I have, states only one IMEI number.
On top of that. Last night I did some more flashing. And I flashed the EU version to see what would happen. Well two IMEI numbers showed up. BUT, thwy were the exact same IMEI number.
So I think it's safe to say, and from reading other articles last night that, either the second slot(if really there), is blocked by the software or the extra set of pins inside are just not connected to the main board.
Unfortunately, I have given up on the idea of trying to get dual sim out of the TMO variant. I had read on the Oneplus forums last night of people complaining about this exact problem. And their conclusions are basically what I just said. They have given any hope of this phone having any chance of dual sim activity.
Apparently when TMO first advertised the phone they advertised it as dual sim. But the next day their ad was changed to say that it was only a single sim phone. And that seems t be the case here.
People have also said that anything made after the 8T, will not have dual sim anymore on Oneplus phones. esim/nano sim is apparently the future
But thanks everybody for all your help. It was fun but ... you have to cut your losses at some point.
And too bad for Oneplus. This is really going to backfire on them.

Update: Duh ... I just looked at the back of the phone for the first time while packing it up, lol !! And there is an IMEI printed on the back cover. Only ONE IMEI ! It was being hidden behind the sticker that was on it. And I never bothered to look.
It's good that you've got to the bottom of it!!
Would you consider looking at the other models NA, Global and Eur checking which bands you need.
If you then find the one that suits, you can always give that a go and have 2 Sims.

No I didn't. I went through reading about it and thought the risks outweighed the chances of it being successful. So I returned the phone unfortunately. But those phones only have one IMEI # and what this method does is use the same IMEI and just adds a zero or two at the end. It's not a long term solution.
