I want to get calls from Android CallLog.Calls which were made from a specific SIM. Is there's a way to check which SIM was used to make call? The following method allows to check SIM when call is performed and app is running. (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE).getSimSerialNumber(); How to check which SIM was used to make calls before app is installed?

In the CallLog.Calls class, there don't seems any field that keeps SIM Information (like which SIM is used while making an outgoing call).

So, I guess it make no difference if your app was installed or not installed, the Call Log Content provider does not seems to maintain SIM-Sepcific, such as from which SIM the call has been initiated.

  • Does it mean that if user changes SIM card in a single-SIM device, it's impossible to check which one was used to make a call from log? – Dubrovin Feb 03 '15 at 11:15
  • i guess you may try `telephonyManager.getSimSerialNumber();` to get SIM serial number which is unique within the operator. Save this value and later if you change the SIM card, it should return you different value. This way, in a single-SIM device, you can still obtain info. I myself didn't try that though but worth trying once I guess, if it is your core functionality – AADProgramming Feb 03 '15 at 12:30
  • @ AADTechnical, thanks for the advice, it works. But I need to know if it's possible to check which SIM was used to make a call before app is installed. – Dubrovin Feb 03 '15 at 16:41
  • AFAIK, this can only be acheived by "sticky" broadcast , to which your app can query as and when it is installed on device. But I never heard of any Android system broadcast that populates SIM Info when SIM is added/pulled from Device, which is STICKY. There is a Broadcast in Android when SIM state change `android.intent.action.SIM_STATE_CHANGED` .....but your app can only get it when it is already installed on device. – AADProgramming Feb 04 '15 at 04:41
