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;
    }
