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)
Hi,
So I was thinking, is it possible with some driver may be to make a virtual copy of a physical SIM card, possibly copy 3-4 cards and make the phone work in multi-card mode without the need of SIM cards being physically present?
now that would be nice, a great idea, im pretty sure someone could make something like this since like other phones like sprint dont have a sim card sometimes are programed directly to the phone maybe its the same prosses.
also would make it easier for many like me that have 2 or more sim cards i myself have a T-Mobile (US) and Movistar (Mex.) sim cards and its a bother to have to change them when visiting like right now im in Mexico at the moment.
but it also would bring up another problem to have something like that.
for example someone gets your sim card (if you dont know anything about such program and if made) and someone with mischeif on their minds saves your sim information and uses it as they please. (then again. its just like stealing your phone, you would call your provider and disactivate it so no further charges would apply the second you knew that something was up. its just harder to know since you would have to wait till the bill comes in)
but if at all possible i would use it for good. would be nice

Indeed, i hope it is possible. I dont think theft would be any problem at all, because the gsm network should not accept simultaneous login from the same SIM card. It just makes sense to be this way. I myself have to use up to 5 cards and growing. Ultimately, virtual SIM cards would also enable purchasing cards from the internet and also cheapest route selection, things like this..
point made.
you have a point.
i forgot about the network not allowing you to have two at the same time.
but yeah then again, it shouldn't be much of a problem i think. 5 cards is alot.
but you're right if such a program where made, it would open the market so mucho more and one could actually buy online sim card info. and if this program where made, one could save the info to the phone then back it up to a computer (where it's safe, most of the time atleast) and maybe the same program could write back to a sim card thats not activated (for purposes just as loosing a sim card, but not the info.) now there's an idea for ya.
would be super nice!
too bad i have no clue on how to program such things, but ideas i have
if anyone takes the challenge to create it, if at all possible i would gladly donate since i would use it surely.
Possible, but..
It's possible if you have the Ki and IMSI values from your SIM. The IMSI is easy, but cracking the Ki is only possible in old SIM cards, using COMP128-1 encryption.
All the SIM cloning tools on eBay can clone only these old cards.
A virtual sim card is a really cool idea. No more swapping sim cards between you primairy phone and your backup phone... (I only have only one sim)

Hi
No they give you the IMEI number not the IMSI.
The problem you would have is that sooner or later the networks would block your phone because they will see the fact that your phone is running 4-5 mobile numbers with ONE IMEI no. Ebay is littered with Cheap dual active SIM phones. They only have one IMEI and sooner or later the network(s) will switch off your phone.
The way round this is to have 2 IMEI numbers to run 2 sim cards at the same time...abit like the Samsung D880. This basically means you have 2 phones with 1 screen and 1 keypad...i have one and i know these work great!!.
Regards
Wasim
The will not block you for changin sims, right?
And also GSM won't allow you to register simulteniously two sims, only one at a time...
Cos TD has only ONE GSM inside, not two as Samsung DuoS
What the progress of the topic, people?
I certainly hope this is not possible. I wouldn't want to know anyone can copy and use my simcard. That would be an unacceptable breach of security for any mobile phone user.
This might be a good breach, and it exists, just need a tool to use it with windows mobile! I can even now COPY MY SIM to another sim, yes - it's need a liitle crack with it, but card itself intact, and i can have a copy
So - What are solutions now for windows mobile?
i really like to know if it is possible. but i dont think an emulator is a must because in ppc we can easly turn off the cellular connection and turn it on again. that way (if you've used old 3in1 sim cards, you'd know) you can change the operator. every time you restarted the gsm connection, your operator will change.
and what about connecting to more-than-one operator at the same time?
cheers

I am in Saudi & have 3 sim cards(STC) with the same number. One in my laptop, One in my Samsung, one in my Diamond. All work for internet at the same time to use for phone I activate by *123$ (this is then primary card for incoming & texts). When in Spain I have 2 cards(Movistar) both of these work & ring at the same time, but text messages only goes to one of them.
Virtual Sim Card
hello ladies and gentleman this is a very good idea i was thinking about the same idea today... In the virtual sim card there should be a tracking device installed in the phone so that when it is stolen you can track down the phone or the company can switch of the phone and it will have no use and all your data is safe... I am all the way in africa Botswana and my name is delmar dube i am willing to do more research on this because i want to see it come true
I would be surprised if this was possible... the GSM chipset firmware is pretty much sealed off from a phone's operating system except for the AT command interface. Otherwise people would be able to fiddle with transmit power which would invalidate the phone's FCC/etc certifications.
Any progress??
Heyy like most on this forum thread I just thought of this last night, I have an unlimited plan with Wind Mobile (who's coverage is um.... not great) with Unlimited internet and talking and texting for $29/mo. Unfortunately I spend the majority of my time outside their current coverage area, and would like to get one of Telus' "One Number Unlimited" voice plan ($7/mo) for when I'm outside of Wind's area but still want to call my girlfriend. Virutal Switchable SIM cards would be a great solution since my phone doesn't exactly like to co-operate with me when I try to turn it on after having the battery removed to get access to the SIM slot. Plus I don't want to be carrying around a little tiny piece of plastic that'll give me chaos if I ever lost it.
Anyways I'm running a Samsung Galaxy Exhibit 4g (4g is the name of the phone, it's just LTE of 3G though), It's running ICS 4.*something.
Oh yeah, sorry for being a grave-digger
I love this idea. I mean apple now has patents for virtual simcards, I really hope the android market follows suit. I have 6 sim cards and counting (Afghanistan, Switzerland, United States, Korea, Philippines, and UAE), and would love to be able to purchase and activate my "virtual sim card" off of say the Google Play Store, prior to flying into a country.
I wouldn't mind some kind of DRM or whatnot, just being able to buy service before I go into country, and then have calling and data capabilities as soon as I walk off the plane would be worth it.
I have a korean Galaxy S2, which has the sim tray damaged, being impossible to connect any SIM card.
If I could use virtually my SIM card, I coud use this phone.
Is this possible??
I just wanted to use one SIM card just for phone calls, dont even need services like internet...
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:
http://www.amazon.com/LOPURS-Adapte...6-6747327?ie=UTF8&refRID=103H6N95BRG8HE3ZM64C
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.
