Hi,
I just bought a TP2 and is very happy about it - it is far better than my old Diamond.
I'm quite tired of having to carry two phones around; my private mobile and my work mobile, so I'm looking at a Dual SIM adapter.
But I first of all want to hear Pros and Cons for using this.
When I google the subject I see a lot of old Posts dated back to 2004 ~ 2007. It's hard to find any up to date review or comments regarding this subject.
So have any of you lads experience, recommendations or even advise against this?
Thanks,
CBW
im interested too! someone pls shed some light
Personally I do carry 2 phones and I have tried dual sim adapters not for TP2 but for diamond1 and pro1 they do work but the performance is not that good.
Cons:
- You can only use 1 sim at a time. So 1 sim will show as switched off even though it is there.
- Some (most) chinese adapter only work with GSM therefore your data conection will be waaaaay SLOOOOOOOOOOOOOOOOOOW.
- It takes time to switch.
Pros:
NONE that i can think of.
Advise:
Peopple just carry 2 phones working at same time both on and both working with 3G ( if your phone is capable and you need data conection)
Buy a dual sim mobile phone (samsung d880,d780) is very good for this
Chinese dual sim phones which are quite good and work perfect.
Problem with dual sim phones is that NONE of them is 3G all of them untill now are GSM. This does not work for me because one of my numbers is on Three UK so i cannot even think of a gsm phone.
Currently using TP2 on voda and SEw995 on Three. and it does the job for me.
Sorry for long post but you might find some info usefull.
I use software called magicall and I believe one of its functions can have a call forwarded to whatever number you want. It may not be exactly what you were looking for but some type of call forwarding might cut down on missing calls when you don't want to carry two phones.
or there is the acer dx900 which is a true dual sim windows mobile phone. i looked at it, but decided against it as the spec was not a huge leap from my old touch cruise. i got the tp2 instead and decided to stay with 2 phones!
Hi,
Thanks for all your posts. I got much wiser regarding this subject. The conclusion is that I will stay with my two phones for now.
Dual SIM adaptor for the TP2 doesn't work as well as either 2 phones or a dual SIM phone such as the MINI IPhone found in China. Funny thing is that a clone manufacturer can make a Dual SIM simultaneous solution. Both SIM cards work simultaneously in the phone but you don't get any advanced software features such as a real WM device >.< . If you want to use a cut-up dual SIM, they are compatible with the TP2.
Hi,
Just wondering if anyone knows of any dual sim adapters that work with the HTC Wildfire? Tried googling but the sites that come up only list adapters but do not seem to promise that these adapters work with this phone.
Have a personal number and a work number that are separate and it would be handy to just carry around one phone.
Thanks
Dual Sim for wildfire
You got me interested in this and my search came up with this company that says it does work with the wildfire
cant post the link because of forum restrictions, but if you google the company at simore.ch you will be able to find it from there. It says the platinum and platinum plus are compatible.
They seem really good and have videos showing how to do every step. The only thing that worries me is having to cut up the sim cards which I hear is normal for a dual sim adapters.
I just got a 26th gen cutting Magic Sim dual sim for my HTC Desire from a seller on ebay (he was the cheapest seller by a mile) i've also tried it in my girlfriends Wildfire and it worked a treat!
If you want info on the seller i got it off just PM me as i doubt i'd be allowed to post it on here.
Cheers
R
yeah, love to have one too
i advice you to do not do that becuas it use so much of the battery near 3x
when you have the duel sim in it.. can you be could by both numbers. or do you have to switch firts to be reached at one of the numbers..
Because i'm loocking for somthing that i can be reachable at two number at the same time..
sorry of my englisch.
Its extremely unlikely that both will be reachable at the same time by using those adapters, although I havent seen / used them personally.
If you want a dual standby phone, get a proper Dual SIM phone.

Here in the philippines its normal to have dual sim phones, also we do have tripple sims because we have 3 different network provider....
But i dont suggest to have dual sim on HTC
1 it destroys the quality
2 it voids warranty
3 it suck to put dual sim on HTC phones. it lowers the value

Hi. I'm thinking of buying a Dual SIM adapter. I would like to know if anyone has it, I would like some opinions and see if are any problems for GSII.
Thank you.
Hello,
I'd like to see you search before posting. I'd think then you would have found this: http://forum.xda-developers.com/showthread.php?t=1190250&highlight=dual+sim
No thanks!
Thanks, I did some research but I had not found this.
I doubt you did, because when you search for "Dual Sim" on the Galaxy S2 section that topic is the first hit..
Really? I tried not only in this section, I did a search in all sections and Google.
The point of a forum is to ask questions, questions will always be repeated, since new users join regularly. Dual sim is a topic that should be refreshed, since new developments could happen. But unfortunately, I do not think there are any new developments, the consensus is to save your money. None of the dual sim adapters currently available have been said to work. There are no reports of successful usage of dual sim adapters with the S2. I would LOVE to have one since I travel between HK and China frequently.

I successfully use a dual sim adapter with my S2. Naturally, it's a switchable system, so you won't get both of your sim cards active at the same time.
I'm using an older generation of Magic SIM, so sim cards work in GSM mode only.
I bought this version of Magic SIM couple of years ago for few bucks literally, for me works just fine.
P.S.: I guess this would be a first report of a working dual sim adapter you've heard about
Thanks, that's something. I look forward to some opinion, however, for those who use UMTS / HSPA, perhaps the last model.

Thanks again. I want to know if anyone has problems, and such.
is it reliable to use dual sim adapter?
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
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.
