Question Single to dual SIM possible? - Realme C21

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.

Simore - Dual SIM

Hallo everybody.
I have a corporate sim without Internet traffic, so I would have a second private SIM card to use to surf Internet.
I was looking at Simore solution
http://www.simore.ch//en/mobile_phone_accessory/HTC/TOUCH.html
I have some doubt, because the SIM insertion space is very very tiny.
Someone has tested another solution yet? Thanks
Well, if you were to look at the installation guide video (bottom of each product page), you would see that, the dual sims method they are using is by trimming your existing sim for the job. Hence, you basically cut your existing SIM to almost 1/2 size of a normal SIM, and put it into the adapter, which is a standard SIM size, hence ought to work (with all phones, size matters). Howver, it is surprising that the smaller one cost less than the bigger version
Bought a 16th gen dualsim adapter, will review it when i have it.
I have it!
It's easy work to make your sims the size it's required to be. Just use a very sharp scissor as it will make the progress easier.
My Vodafone simcard works flawlessly, though my t-mobile simcard refuses to do anything. Might be because i cut it the wrong way / too far inside / or the t-mobile sims are just *****es.
Fitting in the slot isn't that big of a problem, getting it out it.
You need some patience to get it out, but once everything works flawlessly, you'll never need switch sims again.
Ill post images if people want to see it.

Can you give us the link where you bought it please?
www.ebay.com It cost me €10 and some patience instead of ±€15 exc. shipping fees
If you know dutch here's a shop that sells them.
http://www.dual-sim.nl/
and i have a (maybe not too elegant) solution for the issue of removing.
Cut a can in pieces, cola can, bullit can, whatever can.
then cut a piece to shape so that it firmly fits between the metal "housing/holder" and your sim cards, with a piece sticking out side of the housing next to the "stop". (see pictures for more explanation)
If you see it you'll understand what i mean.
I too have this issue... Will both of the phone numbers ring when inserted or do you have to make one the master and the other one redundant if you know what i mean? I have 2 business phone numbers - dont ask! - and i would love to have them both on my Elf.
I am sick of carrying 2 phones around and would love a all in one solution... Especially since my other phone is very close to dying at the moment!
no. you can't get both working at the same time. you'll have to switch on/off (e.g. flight mode) to switch between them. only one can work. there are, however, some phone from china that uses a dual-sim phone (a whole phone, their phone, not sim adapter) that, as according to them enable both sims to work at the same time. these china folks are gooood.
So you say that there's no problem to insert the metal case into the ELF Sim slot ? This is my major question, because I think that the tool is absolutely good, but I'm concerned about the room to insert it into an ELF sim'slot.
Thanks to all.
There is no hussle to get it in there, just a bit tricky to get it out.
I got my 16th gen dual sim working fine now!
Both my T-mobile AND Vodafone sim's work.
Switch, soft reset, and voila! My other phone number is online

Hi Maseo, where did you purchase the dual sim adapter and do you think it will work on a TyTN2 ? Should it function with the DUALSIM TODAY software ?
Thanks !
i saw a simcard to which you can clone around 16 simcards, so you will have an additional menu where you can select which sim to use. you won't need to cut your sim - just a small usb-stick sized device which will read data and settings from your sim and will record it to the new simcard. you will still be able to use your original sim afterwards!
imho, this is a better solution. the only downside is that not all sims can be read.

I've heard about that. The previously mentioned dual-sim.nl has such a dual-sim adapter as well: http://www.dual-sim.nl/product_info.php/products_id/148 (the dutch version) and http://www.dual-sim.eu/product_info.php/products_id/137 for the English version.
Drawback is that only V1 simcards (the very old ones) can be used for this tool. Nonetheless, the card has a regular dual-sim function as well.

Samsung is offering a proper dual SIM phone
It has dual radio so you can have both sim cards active, with the sim kit adapter basically you can switch between sims to make calls but only one of them will be active at any one time which in many cases isnot that useful

single vs. dual SIM

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?

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

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

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.

Samsung S9 European Dual Sim

I've been given a GM960F S9 from work to use as my company phone.
From what I can read online there is no difference between GM960F and /FD in Europe and some phones have the mode 960F and are dual sim capable.
I managed to source a S9 Sim Dual Sim tray but when I put two sims in there only one shows up - is this a software restriction / is it possible to override and make this dual sim?
Thanks!

if it physically doesnt have 2 sim readers, then no. If its the g960f vs the g960f/ds then no. Do you have a dual sim card tray that you can pop in it?

We can finally order dual-SIM trays via eBay as of today. What are the odds of being able to enable that second slot?
It might need some time. I read from other post that oneplus 8 pro took a year before a low that feature. now oneplus 9 pro only have one sim tray so it might talk even a longer time for them to release that feature. I am more depending on the people who know how to customize the rom and add feature . So just stay tune at different forums.
OP9Pro normally comes with a dual SIM. Just flip over your sim tray and insert the second sim. Voila!

That's great news. I returned by OP9P NA variant, but don't have a global variant yet. Shouldn't it just work with the NA variant if we flash a global ROM on the same device? It looks like it has pins on both sides.

Not that simple I think. I already flash to EU tom but it does not second sim in the settings. I think it might need wire flash of all components including baseband

Oh no. Does OnePlus publish those components, or are we out of luck until someone figures out a way to get them? The EU variant I have on order doesn't support one AT&T LTE band, so would much rather use an NA variant with dual SIM enabled.
If the EU variant shows up at my door before someone figures out how to make dual SIM work on the NA variant, then I will just use it even with the missing LTE band.

I saw one guy on Reddit complaining of the same situation we're in- ordered the phone when it said dual-SIM and trying to return it afterward.
He claims OP customer service said dual-SIM would be enabled via update in the future. While I hope that's true, it's the first and only time I saw that said anywhere. Could've just been said to try and avoid return. Even if it does happen, it'd probably be a ways off.

I chatted with OnePlus customer service two different times. Both agents tried to talk me out of wanting Dual SIM, but were very clear that it is single slot only for the US. One even cited spouted some bull**** about doing that to optimize 5G performance on US networks.

I guess we have to wait to see if anyone can figure out how. At least, just upgrade to a newer version of EU tom does not work. Not sure if you for flash everything and reset from adb is the same
i have a bnib stellar black chinese version dual sim 8/256 oneplus 9 pro for sale. I am in SF bay area.
Will it work if i have a Dual Sim Oneplus 9 from Malaysia, install NA rom to open more BANDS ? The malaysia OnePlus 9 has the same 5G bands as in UK, but lack of some US 5G bands like n71. All CN variant do not have B13 band, therefore, not supporting Verizon LTE nicely. All ebay sellers who claimed dual sim with 12GB RAM and 256GB storage are mostly CN variant. I'm better off with EU/UK or MY. Hong Kong spec is the same as USA with dual sim. If anyone wants a dual sim and want mostly all US bands supported, Hong Kong Oneplus seems to be the right fit. Only if we can get it from HK

wait what?! both SIM fits in the same compartment ?
wouldn't that be too tight?
mine only has a slot for 1 SIM
The dual sim versions have 1 sim on each side of the tray.
Mine came with dual sim out of the box and is working perfectly.
I really like how I don't have carry around 2 phones anymore.

Do you have the US version?
I was very disappointed that the US version didn't come with a dual sim. I ordered mine at launch, when their website said that it had it.. Anyway, I finally figured out an acceptable replacement option for mine. I did have 1 sim for my personal number and a second sim for my work number (worked great on my OP 6T for a couple of years now). After playing around with things, I finally ended up porting my work number over to Google Voice (1 x $20 fee) and installed the Google Voice app on my phone. Now I essentially have 2 #'s on one phone, just like having a second SIM, but no cost to my carrier. I can receive calls and txt's for the # I ported to GV. Wasn't quite the solution I was hoping for, but now I no longer pay for that line.

I don't think is a US variant. As far as US Variant is concern, is single SIM. Anyone that is using Dual sim could be CN or EU/UK Variant. If it is indeed a US variant, then I'm interested to know where the source to get it then . Those variants have fewer 5G sub-bands compared to the US except HK. I just hope that Oneplus has the hardware embedded and is just a matter of software activation. Samsung Note20 new firmware patch also opens up their eSIM support.

You do know they make an app called second line right? So you don't need to pay for 2 plans
