How can I check whether the Sim Card is available in an android device?

Question

I need help checking whether a device has a sim card programatically. Please provide sample code.

Answer 1

Use TelephonyManager.

http://developer.android.com/reference/android/telephony/TelephonyManager.html

As Falmarri notes, you will want to use getPhoneType FIRST of all, to see if you are even dealing with a GSM phone. If you are, then you can also get the SIM state.

TelephonyManager telMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);     int simState = telMgr.getSimState();             switch (simState) {                 case TelephonyManager.SIM_STATE_ABSENT:                     // do something                     break;                 case TelephonyManager.SIM_STATE_NETWORK_LOCKED:                     // do something                     break;                 case TelephonyManager.SIM_STATE_PIN_REQUIRED:                     // do something                     break;                 case TelephonyManager.SIM_STATE_PUK_REQUIRED:                     // do something                     break;                 case TelephonyManager.SIM_STATE_READY:                     // do something                     break;                 case TelephonyManager.SIM_STATE_UNKNOWN:                     // do something                     break;             }

EDIT:

Starting at API 26 (Android O Preview) you can query the SimState for individual sim slots by using getSimState(int slotIndex) ie:

int simStateMain = telMgr.getSimState(0); int simStateSecond = telMgr.getSimState(1); 

official documentation

If you're developing with and older api, you can use TelephonyManager's

String getDeviceId (int slotIndex) //returns null if device ID is not available. ie. query slotIndex 1 in a single sim device  int devIdSecond = telMgr.getDeviceId(1);  //if(devIdSecond == null) // no second sim slot available 

which was added in API 23 - docs here
