Try this :

            Secure.ANDROID_ID);
    Toast.makeText(this, deviceId, Toast.LENGTH_SHORT).show();

android.provider.Settings.Secure.ANDROID_ID

A 64-bit number (as a hex string) that is randomly generated on the device’s first boot and should remain constant for the lifetime of the device.

Try this:

// IMEI No.
String imeiNo = TM.getDeviceId();

// IMSI No.
String imsiNo = TM.getSubscriberId();

// SIM Serial No.
String simSerialNo  = TM.getSimSerialNumber();

// Android Unique ID
String androidId = Settings.Secure.getString(this.getContentResolver(),Settings.Secure.ANDROID_ID);
