I would like to make APP which simulates SIM card in software on android. I would load 2 or 3 SIM cards into phone and then I would chose which one I need in android.
Do you think that it`s possible to be done? I don`t know how phone communicates with SIM card, it`s by SW or HW?
Thanks for any advice.
to make it more clear what I want, I want it to work like deamon tools in Windows for cd-rom, but i want to emulate sim cards
You can get most of the source code from market enabler or market access. It does that in order to allow users to buy apps
XDA App
Actually I doubt that it's possible to emulate SIM card, take a look at http://en.wikipedia.org/wiki/Subscriber_Identity_Module at least.
The SIM card is designed not to allow the Ki (Authentication key) to be obtained using the smart-card interface. Instead, the SIM card provides a function, Run GSM Algorithm, that allows the phone to pass data to the SIM card to be signed with the Ki.
Thanks for reply. Market enabler doesn`t do what i really need. As I looked in the source code of it I found that it only rewrites system variables in which is stored Operator ID and string ID of Operator.
I know SIM cards have protection, but I know that there are ways to copy it, don`t know how yet but it`s not my problem right now. My problem is if it`s possible to emulate it in android or not if I will have it copyied.
Thanks.

Maybe some of you heared about the "magic card", which contains more than 1 "real SIM card" (in fact, KI/IMSI pair) in it, and can switch to any one by restart and enter the right PIN code. Please follow the link to see more detail.
And I found a Simen SL45 patch named kvSIM may simulate a "magic SIM card".
So does it exists such a application that may simulate one (better more) SIM card(s) running on Windows Mobile system (hence, phone may operate without a real SIM card in it)? or anyone is intersting to develop one?
I believe that the applicaiton will great benefit the vast users. :lol: :lol: :lol:
i'm interesting
does anyone know?

Hi!
Could someone point me to info how can I use SD card as real Secure storage of data?
What I need to do - to use it under Win Mobile platform?
is Any 3-rd part software available?
thanks for any information.

I guess it depends on how you define secure?
If you mean 'nobody else can access the data if they get a hold of the card' ... there are many articles on the web discussing this issue - here's a decent (but slightly dated) one: http://www.windowsecurity.com/articles/Securing-Pocket-PC.html
There are a LOT of app's which will provide you with varying levels of encryption for your data - Resco Explorer has an option to encrypt, for example.
Use google (or your preferred search engine) to search for "pocket pc" and "security" (or perhaps "encryption") and you'll get plenty of hits.
I must point out though that we are talking about an extremely portable device. A PDA is just so easy to steal! An SD card is even more so. So if you are talking about data which really MUST remain secure ... you may well be better served by not putting it on your unit in the first place.
Hi
Actually we wanna do a simple thing.
we wanna put our application and data on SD card and allow access to this storage only to someone who have right to do it. (it isn't top secret )
SD category 3 of levels of SDMI security requirements will be fine for us.

But as I understand - there is some problem with it. It is a little bit strange - because every normal SD card has to provide this feature (and it is), but just there is no any suuport of it from OS? even there is no some 3-rd part File System Drivers?
It isn't sounds so hard to implement.
Why do I feel like we got gipped again?
I believe SD is a scam over MMC cards just like 1.44MB 3.5" floppy disks was a scam over the 720KB version... :x

I did some research into SDMI last year, as a part of a contract I was on. I've dug into my notes and found this:
http://www.microsoft.com/windows/windowsmedia/drm/sdksandversions.aspx#version
It may be of some use to you. Probably not ... frankly I find the whole approach of DRM to be a joke
Hello,
I am trying to access to a SIM application, I have some questions and I have been reading more or less the entire Development and Hacking section before posting. I hope you can help me:
1) We are able to create new applications for the SIM (we have some Test SIMs from a manufaturer). Is posible to select among diferent applications in the SIM by their AID?. How can I do that using RIL?
2) In the post http://forum.xda-developers.com/viewtopic.php?t=41182&highlight=season, it was said that a season interface can be used to sniff the traffic betwen the sim and the mobile. I have also a season interface prepared and attached to the mobile phone. But the logs I obtain don't make sense. Which program can be used to obtain logs?. If developed individually: In that case which connection speed, parity bits, stop bits, bps speed... are necessary to access that data?. I am using 1 start bit, 8 data bits, one parity bit (even) and two stop bits. My mobile phone is a Qtek 9000.
3) Does anybody have some sample traces among the card and the host?
4) Somebody have some working code to interact with the application?.
5) Mi mobile phone has a driver called SIM, and another SCARD. Do you know if it is possible to access directly to the card using that driver?.
Please any help will be appreciated.
Thanks for this forum and for your comments!!

Please, can anybody help me?.
Thanks in advance
Please, any help?
the STK service is most of the time a icon that looks like a sim card and gives u info like credit balance on [payg] and the phone number to that certain sim card and other options etc.
the problem i am faceing is that whatever ROM i have tryed when i select a item that has to get in touch with vodafone [as that is who i am with] i get a internal error.
example- i choose to check my balance left on [payag] and i get = internal error, code 2E04
but doing the same thing on a run of the mill mobile, example- a sony ericcsonn k750 all is ok!
the windows mobile device is a o2 xda II himalaya running ROM'S from this very excellent forum.
any ideas or workarounds greatly appreciated and thanks in advance!
Hi everyone,
the SIM I use in my android phne contains some strange settings. The Line1 number field is empty (which is a bit annoying to identify the correct SIM in my dual sim phone) and the operator name field content is weird since it contains "Willkommen" (german word for welcome) instead of the company name that sold the SIM, which is the usual content. In case you figure out similar behaviour of your phone, validate the SIM's field contents with SIM +.
I've found out, that there is an API class "TelephonyManager", that can deal with these issues by providing the methods "setOperatorBrandOverride" and "setLine1NumberForDisplay". So at least on the lowest level of customization there is a way to get rid of the described issues. Since I am (still) not familiar with Android application programming, can someone tell me, whether there are apps around, that can fix thebehaviour or whether there is a method how to deal with the API without designing a highly sophisticated app?
Thanks a lot in advance! :good:
