How can I check whether the Sim Card is available in an android device?
Thanks @Arun kumar answer, kotlin version as below
fun isSIMInserted(context: Context): Boolean {
return TelephonyManager.SIM_STATE_ABSENT != (context.getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager).simState
}
Found another way to do this.
public static boolean isSimStateReadyorNotReady() {
int simSlotCount = sSlotCount;
String simStates = SystemProperties.get("gsm.sim.state", "");
if (simStates != null) {
String[] slotState = simStates.split(",");
int simSlot = 0;
while (simSlot < simSlotCount && slotState.length > simSlot) {
String simSlotState = slotState[simSlot];
Log.d("MultiSimUtils", "isSimStateReadyorNotReady() : simSlot = " + simSlot + ", simState = " + simSlotState);
if (simSlotState.equalsIgnoreCase("READY") || simSlotState.equalsIgnoreCase("NOT_READY")) {
return true;
}
simSlot++;
}
}
return false;
}
You can check with the below code :
public static boolean isSimSupport(Context context)
{
TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE); //gets the current TelephonyManager
return !(tm.getSimState() == TelephonyManager.SIM_STATE_ABSENT);
}
Use TelephonyManager.

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
