Answer 1

I think Sim serial Number is unique. You can try this.

TelephonyManager telemamanger = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
String getSimSerialNumber = telemamanger.getSimSerialNumber();

Let me know if there is any issue.

Hi Prabhu, Could you mention the solution you have got for your issue? – Peddle

What about multi sim mobile? – Heavily

Answer 2

This is a known issue. Many SIM across the globe would return null. You should rather use IMEI number however even that can return null.

TelephonyManager.getDeviceId()

Overwork

Answer 3

Look for TelephonyManager.getSubscriberId(), this will give the unique id for each SIM.

Hey, TelephonyManager.getSubscriberId() gives same id for two different sims of same network. I am using serial number of sim to uniquely identify sim – Paralysis

No, getSubscriberId return you unique IMSI value for GSM phone, even if you have two different sims of same network. Check this developer.android.com/reference/android/telephony/… – Formication

On some phones or networks only the first 6 digits of the 15-digit subscriber id is returned. – Boilermaker

Answer 4

With API Level greater than or equal to 22 : You can access all the SIM details using SubscritionManager. Use following command to list all Sim numbers(Works well for Dual Sim also):

List<SubscriptionInfo> list = SubscriptionManager.from(getApplicationContext()).getActiveSubscriptionInfoList();
for(SubscriptionInfo s : list){
   Log.d("SIMMANAGER",s.getNumber());
}

Note : This only works well when the operator stored their mobile number in sim card. Else, this method returns null.
