About feasibility of Virtual SIM - General Questions and Answers

Hello.
I'm just studying about feasbility of Virtual SIM.
I know that every SIM has one Ki and IMSI information and there are many dual SIM holders that provides STK functions.
If I want to make a dual SIM like SIM-Max or 10-in-1 SIM, what sould I do?
Here is my idea.
Is there anyone who can tell me the idea below is correct?
1. Contacting a SIM card manufacturer like Gemplus(Gemalto).
1.1 Buying an SDK
1.2 Buying some Java Based SIM Cards.
1.3 Programming for SIM card, which is compatible with GSM11.11, GSM11.14
2. Getting two IMSI and two Ki from two existing SIM(which has COMP128 v1) for test.
2.1 Copy the information I have got to the programmed SIM.
2.2 Toggling with STK menu.
3. Contracting with two operators.
3.1 Buying a serial of information from the operators, for example AT&T(US) and Orange(UK), where the information is IMSI and Ki.
3.2 Putting the information to the programmed SIM card.
4. implementaion of OTA function.
4.1 Ki and IMSI downloaing STK applet.
If this is possible, I think I can make dynamic virtual SIM for roaming users, where user can download an IMSI and Ki information.
Please reply to this about the feasibility.
Thank you in advance.

Develop a MIDlet access to SIM and SIMToolkit through APDU

Hi,
i've to develop a MIDlet application that might access to SIM functionality (like PIN, phonebook, ecc...) and to SIM Toolkit application usign the SATSA APDU protocol. The SIM that i have to access is not a java card but a simple 128kb SIM of an Italian operator.
I read that for access to SIM toolkit i have to know the Application Identifier (AID), what does it means?!?
Someone know were i can find more detail information about this argument, in particular the specfic APDU command to comunicate with the SIM in both case?
Thank you very much
Though this is related to dev & hacking, we're keeping questions on all subjects in the Q&A section.

dual sim development

hi i was wondering if anyone has looked at dual sim development on the dream yet ive got an adapter but it isnt working
I have one on the way... here is what I've found
So far the STK hasn't been added to android yet it is due in the next release from the little "this is when this android part will be finished" list.
GSM primer
GSM is a very standardized thing, but carriers use what they want and ignore the rest, ie: PTT has been part of gsm for years, just not alot of phones support it.
So has fixed dialing, so you can control who calls into the phone and what # the phone can call, just here in the states they want money for that so the TMOB has given us the "family mins gestapo plan" that can limit the times the phone can be used and how many mins they can use and costs 4.00$ a month and AFAIK, it cant control the number which the phone can call or the #'s that can call the phone, GSM is a TCIP compatable network so in theory anything that would run on the net will run over GSM, maybe not at blazing fast speed but it will go...
STK:
STK is a little programming language of some sort, im not a coder(jack of all trades master of just a few) but it allows small applications to control the sim itself this is how multisims work, the have an stk app that will allow you to switch sims, the sim I need to use as a second in my G1 is a V2 so I'll have to do some surgery to cut them, I wont be happy if I kill my simcard as its 1 of the 3 secret KIs I have left to use in my multisim thats a fun hack that has run its course at one point I had all 4 of my family plan phones and a prepaid account all MINE and PAID FOR on 1 sim you can imagine the things I could do back then the prepaid was on another net, it was BEAUTIFUL, and I learned tons doing it, (which is the point to begin with)
disclaimer:
I NEVER USED THIS TO STEAL ANYTHING FROM ANYBODY, JUST TO DUPLICATE SIMS I OWNED, SO PLEASE SAVE ME THE MORAL DRIVEL...
bhang
I'm waiting for STK as well... just to use my dual sim adapter. That would be great, because I'm going to overseas a couple of times a year and therefore I have two sim cards. And I hate to remove the back cover of the G1!
how does your work???
The one I got requires cutting the sims down to just the gold patch, and it switches itself every 2 mins to check for voicemail sms and calls which seems a bit odd, the calls part any how...
hopefully iy comes soon
I'm sick of carrying 2 phones or wrenching the backcover of the G1 it wasn't mean to be open and closed much thru the life of the device.
STK better be in the next release, I can get an old nokia I got when I signed up with tmob a 5160 I think and it does STK just fine... C'mon guys
bhang
got scared about the cutting ang got a no cut
I got the no cut already upgraded to rc33 and no STK
Code:
Q4 2008
Localization
The UI and Application Framework for the Android 1.0 platform primarily targets English-speaking regions. To enable handset manufacturers to deploy devices in non-English-speaking countries, we will support the following localizations:
* Strings localized into various languages.
o Q4 2008: German
o Q1 2009: French, Italian, es_es, zh_TW, Ja, NL, CZ
* UI modifications (tabs, menus, homepage shortcuts, etc.) to support non-English languages.
* New date and numeric formats.
Support for multiple APNs
This feature will enable the different applications to connect to different Access Point Nodes (APNs). For example, a web browser can connect to an Internet APN connection while the MMS can connect to a separate MMS APN.
SIM application toolkit (STK)
This feature will enable the SIM to initiate actions for various operator-specific value-added services.
Guys,
do we know if this is working yet?
Having a look through the official change log from Android it states that they have implemented the SIM application toolkit
http://source.android.com/release-features
Did anyone get a dual sim adapter/ and can they try it out to see if it does actually work.
There is a STK.apk in the Hero release. No idea if it does what you want though.
Where is "Where is my stk!!!! " post?
Someone make working STK on HTC Dream?
I have performed custom build from cupcake source succesfully...
I have performed Installation succesfully...
...but I don't know how STK works.. someone saw how it works?
There is a launcher for an STK session?
I'm trying to access to STK menu on a SIM Vodafone
install the STK.apk you compiled, and run it... (adb install blah.apk, and touch it in the menu on the phone)
I would like to know about this. Should I buy an adapter yet, and if so which one?
No Activity Launcher
Source in git is wrong, in the manifest exist:
63 <!-- SIM Toolkit settings activity -->
64 <activity android:name="StkSettings"
65 android:label="@string/app_name">
66 <intent-filter>
67 <action android:name="android.intent.action.VIEW" />
68 <action android:name="android.intent.action.MAIN" />
69 <category
70 android:name="android.intent.category.DEVELOPMENT_PREFERENCE" />
71 </intent-filter>
72 </activity>
but StkSettings was removed from source.
I have removed from manifest.. but I don't know how send commands..
What version you have?
Exist a STKSettings activity?
I think that STK was removed because is not ready, and the version that it work well is one..but wich?
At STK start what it show? Menu? Input Command?
Custom STK Building with Vodafone Sim work...
Seems to be work with a vodafone sim..
In this week I will recive a Dual Sim Adapter, then test it...
Good night
Dual sim
Can anyone confirm dual sim is working on g1? and witch adapter you use for it?
i'm interested in this information, too
anyone has dualsim running on his device?
noone has it running?
I am eagerly waiting for it too.... Please let us know if any update.

[QUESTION] Two numbers on the same sim card.

Does the magic by default or any other android builds support having two numbers on the same sim card?
And if so has anyone tried how you can call/text from a specific number?
Thanks in advance ppl
My friend this is a general question.. So it should be placed on the General threads... bla bla bla bla...
Now back to the answer.. I think that the question you are making is related to Twin SIM cards. This can have two numbers on the same SIM. If android will run use this cards without prob.. why not? Never tested, but If old phones can do it why not Android?
Not an expert on this but isn't all handling of this happening outside the phone and at the mobile provider ?

Yes, is out of phone question in my opinion too.. But, we can take this question if this phone is capable of reading Twin SIM cards.
Doesn't the phone OS allow the user to choose between numbers?
I posted this under the android subforum cause my question is if the OS supports it and not the hardware.
If the sim has 2 numbers you must be able to choose for example from which one to send an SMS from, or from which one to make an outgoing call.
This is something that android will have to handle.
Am I saying something incorrect here? :/
I managed to find the proper name for this twin sim thingie.
It's called ALS "Alternate Line Service" and is NOT supported by any Android device so far.
I'll try posting on the android google group for some more info.

Dual sim? One sim - two numbers, not two sims!

Hello!.
Hector From Spain!.
I have one "SIM DUO" from one company (movistar).
It is two phone numbers from the same phone company at only one SIM.
Anyone knows about aplication, settings, etc... to manage those numbers: change number, company name, etc...
Thanks in advance!!

I am not sure whether your current ROM has enabled the futures for due line SIM management but you check it under settings--->Personal--->Phone.
In there you should see a page in which you can change the settings for each line. If you don’t have those settings visible right now then get the little free application Advanced Configuration Tool 3.3 and enable those settings http://www.freewarepocketpc.net/ppc-download-advanced-configuration-tool.html

Modify code to register with test IMSI

I am looking at modifying the ROM of an Android device and wanted to know if anyone knew where the code to register with the mobile network is located (ie. the place where the IMSI and KI are used from the sim to initially register with the GSM Network.) I didn't know if that was a kernel function or buried in some subsystem.
bump ...
I think the modem is responsible for that but don't take my word for it.
