Is there anyway I can get mobile number of both SIM cards in android Java?

I want to add the functionality of login similar to UPI apps. The user will select the SIM card from his phone and I will send an SMS from that SIM and will verify his phone number using that SMS. But I have to compare the number in the back-end or in API. So, I want to acquire the phone numbers of both SIM cards or the phone number of the SIM card user selects (Get the phone number from SMS or while sending SMS).
I am putting a generic class that I made for SIM selections and SMS. I have tried getting the mobile number from SubscriptionInfo, but it gives the operator name and all details right except the mobile number which returns an empty string. I have found in different blogs or my R&D that it is up to the operator whether to put the number there or not. So, if I am getting the mobile number, it is not 100% guaranteed that I will get the mobile number every time.
Here's my generic class: SimUtil.java

setupPermissions();
return;
}
List<SubscriptionInfo> subscriptionInfos = SubscriptionManager.from(context.getApplicationContext()).getActiveSubscriptionInfoList();
for (int i = 0; i < subscriptionInfos.size(); i++) {
SubscriptionInfo currentCard = subscriptionInfos.get(i);
SimCard simCard = new SimCard(i,currentCard);
simCards.add(simCard);
}
}

return this.simCards.size();

The response from the onResponse method from Retrofit Library is always returning null

I'm using retrofit to get some data from the API for user login, but when I write all the code for the retrofit and check it's implementation on the emulator it always returns null response in onResponse method.

Your definition of loginUser is:
public void loginUser(String username, String fullName , String cardid)
whereas, when you call loginUser :
session.loginUser(username,response.getString(KEY_FULL_NAME));
You call it with 2 String parameters. You need to provide another parameter, cardid or change the function definition to require only 2 parameters, like this:
public void loginUser(String username, String fullName)

How to pass data collected in arraylist from json asset file in one activity having recyclerview to another activity again having recycler view?

I have an activity named Cardview Activity which has a recycler view associated with it and i am fetching data from a JSON asset file in that. But now when i click on an item of Cardview Activity, I want to send data related to that item only to another activity i.e. People_List_Activity which is again having a recyclerView.

how can i send the Person_Id, Name and Designation to the People_List_Activity ? Please help as i am stuck in the code.

You can send using Intent , by passing your data in Bundle and then pass Bundle into Intent Extras.When you go form one Activity to another .
Intent intent=new Intent(CardViewActivity.this,PeopleListActivity.class);
Bundle bundle = new Bundle();
bundle.putString("key1",value1);
bundle.putString("key2",value2);
bundle.putString("key3",value3);
intent.putExtras(bundle)
startActvity(intent);
And You can retrieve Data in next Activity OnCreate():
Bundle bundle = getIntent().getExtras();
String value1 = bundle.getString("key1");
String value2 = bundle.getString("key2");
String value3 = bundle.getString("key3");

Arraylist keeps overwriting the last entry i added

sorry for troubling you, i am new at android, and i need a little help. I am doing a simple ampplication in which you sign up some people to a club. What it keeps happening is that the last person i add to the arraylist overwries the old one. I really don´t know what it could be. If you can help i would be grateful.

Every time you called the grabar to add the user you have to create a new Socio object. Using the same references will only change object's content
