Use this to disable services: https://play.google.com/store/apps/details?id=cn.wq.disableservice&hl=en But I don't think if this approach is really so good. If people use Google's services they can't expect that Google will ask them...

I don't see how this issue is related to detecting IMSI-Catchers. I'm against implementing it. If someone wants to disable some google services he can use the mentioned app.

Check if service is running - I have -not- found a way to list all components of a package (like DisableService app does). ``` shell dumpsys activity services | grep...

The approaches for extracting Kc and TMSI I found use AT+CSIM command to issue raw APDUs. We can't send APDUs to the SIM, because AT-commands like +CSIM are not supported...

I know now why I couldn't obtain Kc and BCCH. I have a USIM which has an other file structure.  [\- source](http://www.in2eps.com/fo-uicc/tk-fo-uicc-df-gsmacc.html) [Complete File Structure of USIM](http://www.in2eps.com/fo-uicc/tk-fo-uicc-adf-usim.html) I could...

@SecUpwN It's a little more complicated. There can be multiple applications on the SIM (UICC) which have different file structures. USIM was developed for 3G networks. _"SIM cards" in developed...

I went through [EVAs post about the CRSM command](http://forum.xda-developers.com/showpost.php?p=20923894&postcount=2). Reading the ciphering indicator works, but the command for enabling the ciphering indicator doesn't change anything. When I execute `AT+CRSM=214,28589,0,0,3,"010001"` for...

- You can't clone a SIM card to another with the keys. The SIM Card is performing security checks to prevent this. - It would be great to have a...

API 21 is for Android 5 and it is good news to see that there is now a [public API](https://developer.android.com/reference/android/telephony/TelephonyManager.html#iccOpenLogicalChannel%28java.lang.String%29) for transmitting APDUs.

I don't know why this should be relevant. Stock ROMs don't offer a SmartCard API so you can't communicate with the SIM card. Without [patching Android source code](https://code.google.com/p/seek-for-android/wiki/BuildingTheSystem#SmartCard_API_support) for Smartcard...
