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...
I was trying to find a good rate for a flatrate AND telephone costs - but somehow either on or the other sucks for me. I heard of phones which have dual sim, but the Galaxy has only one slot, so an idea came up:
Would it be somehow possible to backup a sim card and simulate it much like cdrom drives etc can be simulated on a pc? Possibly not I guess since it is read by hardware and all that stuff is hardwired, but I don't really know about this much so I wanted to ask you guys who know alot about the internals of the phones.
Its just a crazy idea ... it would probably not be "allowed" either but I'm just interested =)
the galaxy s has a setting that i noticed before it says ''dual sim - no'' was in txt document somewhere in system. what you propose would be a major security issue i certainly wouldnt want anyone else to get my cloned sim so such apps should never be made. you can buy a dual sim adapter they even support 3g and are pretty cheap you can take look at few here browse to second item.
http://www.fonefunshop.co.uk/dualsim/dualsimcovers.htm
Even if it could be done, it would certainly be illegal. The developer who made this possible will face lawsuits from all the major (and perhaps the smaller one as well) carriers.
This would be great feature/software and not only for illegal things. For example - I have a phone, which has something broken in SIM card reader - it gives me "No Sim card in Phone" whatever SIM I use... So with such software I could make an image of my valid SIM card on another phone and would be able to use it with "half-broken" phone
Unfortunately, this is not possible at the moment and my phone is almost useless
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.
I got my Pixel 5, but I don't have esim yet. And I do not want to use physical sim-card anymore. My old phone is Google Pixel 2XL.
I have been thinking how to transfer my old phone to my Pixel 5.
Here is what I thought
1. Make sure old phone is backup (via system settings, backup)
2. Turn off old phone, and take out nano sim card
3. Insert the nano sim card on the Pixel 5 (for temporary while waiting esim)
4. Turn on Pixel 5 and connect to Wifi
5. Restore from the account I use to backup on my old phone
6. Continue setup
I think that would transfer my old phone to Pixel 5.
Once I received my esim, how do I change my nano sim card to esim?
- Turn off Pixel 5, take out nano sim card
- Turn on Pixel 5, configure esim (settings, mobile network, etc.)
Would that work?
And about Google account backup restore, will that also restore all my phone call history? SMS? MMS?
Thanks.
you'll have to contact your provider to arrange them to transfer you from physical sim to esim, generally done with a QR code and pin (at least that's how we do it in Australia).
I done mine through Vodafone Account online, I selected replace sim > esim > they sent an sms to confirm it was me > they then sent a pin by sms > then I got an email with QR code.
After that I went into Settings > Network and Internet > hit the + next to Mobile Network and selected Download a SIM > scanned the QR code and entered the pin, then a few seconds later it was setup and working great. Took out my physical sim and binned it as its now useless.

I did pretty much the same except with a work sim (o2). SAcanned the QR code and notified my work phone people that i wanted it transferring, was on the esim within an hour.
Have my personal number as the physical sim in the phone too. love having not to carry two phones around anymore
Thanks all! Yes, I called my provider and they sent me the esim package with activation code via post, not yet received. But I want to setup my phone now
I have never done this before, coming from Pixel 2XL.
Some companies may charge you for an eSIM, this varies among different countries and different companies. The QR code is for one time use, so if you change your phone, or something happens that you are forced to factory reset your phone, you will need to ask them to send you another one. The second eSIM may carry a cost to you even if the first one is free, and then there is the trouble of not having a SIM while you are waiting for the replacement. I would rather use a physical SIM for the primary carrier that I use in my own country, and use the eSIM for traveling.
(There's an option to keep the eSIM when you factory reset, but who knows what may happen)
In some advanced countries you will easily get the eSIM for free and you can get the eSIM QR from your home probably in a couple of minutes via email or some portal.
In more precarious or corrupt places you will have (like me in Spain with Movistar carrier) to pay 14.90€ to get a piece of cardboard with the disposable QR code (and you need to go to a store to get it) and spend at least 20 minutes to do the entire process until you finally activated the eSIM in the new Pixel
I just did this today. Second time i did this process.
I do this because I like to have work SIM + personal eSIM in one device.

I'm still waiting for Three (UK) to fully roll out their eSIM program. At the moment you can only get them from select stores but they're all Northern stores that I can't physically get to.
FYI, your Pixel 5 will only work in 4G mode when using 2 SIM cards.
Is there any advantage to an esim apart from not having to have a physical card in the phone?

Only if you have two providers. Some don't have eSim technology and you are stuck with a physical sim. And if your second provider is the same you are out of luck. Other than that I don't think there is much difference.
Hi all,
I was wondering if it's worth moving to an eSim from a physical sim. Are there any specific advantages with eSims over a physical sim? I've tried researching this online but there's not much write-up on this...if there's anyone who's using an eSim exclusively, pls do share your thoughts..
I've only been using normal SIMs, but I thought about eSIMs for a while now and this is the way I see it:
SIM:
- easier to change in case you shuffle between more than 2 providers
- can break easier (I've seen a couple of broken SIMs over the years)
- maybe harder to get hit by fraudulent swap
- faster to switch between phones
eSIM:
- all the advantages/disadvantages above become disadvantages/advantages here
Personally I would only go for an eSIM in the following 2 situations:
- my provider forces me to
- my phone has more radios than SIM slots (like iPhones seem to have)
Anyone know if the eSIM can have an impact on regional limitations?
I.e, can one use an eSIM to unlock certain limitations like "Good Lock", "Beta Enroll" etc? Especially if paired with the correct CSC (and VPN if it has to be).
It's incredible to think that all this depends on these four lines that require root to change
Code:
gsm.sim.operator.numeric
gsm.operator.numeric
gsm.sim.operator.iso-country
gsm.operator.iso-country

Oh...I was thinking if there would be better reception through eSim or better battery life given that it's part of the phone's hardware...Any thoughts on this line?
i've been using an eSim only since i got my s21
is a bit of a headache to transfer it - but once its done - is so much easier
i dont need to ever take the sim out or whatever not
and i had better reception and less heating or battery drain
also is easier to control it if someone steals your phone etc
I tend to disagree with @tim2london on a couple of aspects:
- The SIM card is just a means of authentication. SIM or eSIM, the radio transmission is done by the SAME radio module. It makes no sense that one would impact the operation of the said radio module.
- The difference in consumption should be very, VERY small. I'm talking maybe 1-2 mAh per battery cycle. Something impossible to notice even in lab conditions.
So unless the above two paragraphs can be disproved via strict lab tests, I consider them true.
@tim2london how is it easier to control the eSIM in case someone isstealing your phone? As far as I know the procedure would be the same: call your provider and ask for the SIM to be disabled.
Oh, yeah, moving an eSIM to a different phone (for whatever reason) is cumbersome at best.
so you've only used SIM but you seem to know everything and be super sure about it when it comes to esim
even tho i only used esim for nearly a year and i speak from experience
im not interested in justifying what i just said - you want to believe it believe - you dont - DONT
the man asked a question and i answered it - as someone who is only using esim atm
as for the safety thing - someone can easily take the sim out and use it - they cant do that with an esim - they'd have to steal the phone together - they also cannot remove the sim from a phone to avoid tracking as removing an esim is not that easy either
all in all - there are no massive differences - and is mainly about convenience - you can use multiple esim profiles - from different networks - all you need to do to change is click a button

I dont think esim will be better on battery or reception for the simple fact that esim/physical sims have to provide just a number to the phone to catch a signal and register on network which is similar in both cases
I don't know how it is now, but I used esim in the past on project fi and it was a pain in the butt when doing a factory reset. With the physical Sim, it would just my number a text to verify, whereas the esim would not be recognized until the phone was done setting up. Had to use the backup codes.
The reason why I use esim is so that someone can't just take the simple out in case I lose my phone. Unless the person knows my password, he can't turn off mobile data, nor can they disable the Sim, which means I have a higher chance of relocating my device.
@tim2london @aj7400 @calbrs @daniel_loft thanks for the inputs. I didn't think my post would generate so much interest. From what I've read so far, eSims are good to lock the phone completely and even help in tracking in the event of pilferage along with the ease of adding providers based on service - call vs data...there seem to have no battery advantage or network coverage with eSims over physical sims...
Thanks all once again..
Given how little information @amirage has found online before starting this thread, I believe this would make a nice start for a full article on the subject.
I tried to enable 2 eSIM at the same time, that does not work !
So if you are using more then one provider then you will need to leave at least one real sim inside !
Also eSIM it a bit of a pain in my country, because i cannot transfer it to another phone without disabling it and asking the provider (KPN) for a new real SIM, when send i can then replace it for a eSIM.
I have been using an eSIM with Vodafone UK for almost a year now, and I can confirm that there is no difference in signal or battery performance compared to using a physical SIM. Personally, I prefer to use a physical SIM over eSIm's as eSIM's can be a pain to setup! They are supposed to be easy, but the networks make it extremely difficult and its common place on Vodafone UK for things to go wrong, and when they do, expect to be without phone service for some time.
