Android smartphones have become an integral part of our lives, and with the advent of dual SIM technology, managing multiple phone numbers has become easier than ever. If you’re an Android app developer looking to retrieve the phone numbers associated with dual SIM cards programmatically, you’re in the right place. In this tutorial, we will guide you through the steps to get dual SIM numbers on Android using code implementation.
Step 1: Import the required libraries and permissions.
To begin, open your Android project in your preferred Integrated Development Environment (IDE) and make sure you have the necessary permissions for accessing telephony information. In your app’s manifest file, add the following permissions:
"`xml
"`
Step 2: Create a method to retrieve the dual SIM numbers.
Next, create a method in your app’s Java code to fetch the phone numbers associated with the dual SIM cards programmatically. Here’s an example implementation:
"`java
private String[] getDualSIMNumbers() {
String[] dualSIMNumbers = new String[2];
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
try {
Method getSubId = TelephonyManager.class.getDeclaredMethod("getSubId", int.class);
TelephonyManager SIM1 = telephonyManager.createForSubscriptionId((int) getSubId.invoke(telephonyManager, 0));
TelephonyManager SIM2 = telephonyManager.createForSubscriptionId((int) getSubId.invoke(telephonyManager, 1));
dualSIMNumbers[0] = SIM1.getLine1Number();
dualSIMNumbers[1] = SIM2.getLine1Number();
} catch (Exception e) {
e.printStackTrace();
}
return dualSIMNumbers;
}
"`
Step 3: Implement the method in your app.
Now, you can call the `getDualSIMNumbers()` method wherever you need to retrieve the dual SIM numbers in your app. For example, you can set up a button click listener to display the numbers in a TextView:
"`java
Button getNumbersButton = findViewById(R.id.get_numbers_button);
TextView sim1NumberTextView = findViewById(R.id.sim1_number_text);
TextView sim2NumberTextView = findViewById(R.id.sim2_number_text);
getNumbersButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String[] dualSIMNumbers = getDualSIMNumbers();
sim1NumberTextView.setText("SIM 1: " + dualSIMNumbers[0]);
sim2NumberTextView.setText("SIM 2: " + dualSIMNumbers[1]);
}
});
"`
That’s it! You’ve successfully implemented the code to fetch the dual SIM numbers programmatically in your Android app.

How do I get my Contacts from my second SIM?
To access the contacts stored on your second SIM card, you can follow these steps:
1. Open the "Contacts" app on your iPhone 14.
2. Tap on the "Groups" option located at the top left corner of the screen.
3. Here, you should see a list of available options, including your iCloud account, local contacts, and any synced accounts. Scroll down and select your second SIM card.
4. Once you’ve selected your second SIM card, the contacts associated with that SIM should appear on the screen.
5. You can then browse through the contacts, search for specific ones, or perform any actions you need, such as calling, texting, or editing the contact details.
Keep in mind that the method might vary slightly depending on the iOS version and any customizations made by your carrier. However, these steps should work for most iPhone models, including the iPhone 14 with iOS 16.
It’s worth noting that if you want to transfer the contacts from your second SIM to your iCloud or another account for backup and synchronization purposes, you can do so by exporting them from the SIM and importing them into your desired account. This process can vary based on the specific options available on your iPhone and the operating system version you’re using.
How to get dual SIM number in android programmatically?
To get a dual SIM number in Android programmatically, you can follow the steps below:
Step 1: Check if the device supports dual SIM
First, you need to check if the device hardware supports dual SIM functionality. This can be done by calling the appropriate APIs provided by the Android framework. You can use the TelephonyManager class and the getPhoneCount() method to determine if dual SIM is supported on the device.
Step 2: Handle permissions
Ensure that you have the necessary permissions in your AndroidManifest.xml file. You’ll need the READ_PHONE_STATE permission to access the SIM card information. Add the following permission to your Manifest:
Step 3: Retrieve SIM card information
a) Obtain an instance of the TelephonyManager class:
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
b) Get the SIM card information:
– If the device supports dual SIM, you can use the getLine1Number() method to retrieve the primary phone number associated with the SIM card in slot 1 (SIM slot 0):
String sim1Number = telephonyManager.getLine1Number();
– To retrieve the SIM card information from slot 2, you’ll need to use the SubscriptionManager class and the getLine1NumberForSubscriber() method instead:
SubscriptionManager subscriptionManager = (SubscriptionManager) getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE);
List
if (subscriptionInfoList != null && subscriptionInfoList.size() >= 2) {
SubscriptionInfo sim2Info = subscriptionInfoList.get(1); // SIM slot 2 (index 1)
String sim2Number = telephonyManager.getLine1NumberForSubscriber(sim2Info.getSubscriptionId());
}
Step 4: Handle the obtained SIM card numbers
You can now use the obtained SIM card numbers, sim1Number and sim2Number, to perform any necessary operations in your Android app. Remember to handle any null or empty values appropriately.
Keep in mind that Android versions and device manufacturers may have variations in accessing dual SIM functionality programmatically, so it’s recommended to test your code on multiple devices and Android versions to ensure compatibility.
Note: The steps outlined above are generalized and may require adaptation based on specific Android versions and manufacturer customizations.
How do I find my SIM card details on Android?

How to get sim number in android programmatically?
To obtain the SIM number programmatically on an Android device, you can follow these steps:
Step 1: Request necessary permissions
Ensure that your application has the necessary permissions to access telephony-related information by including the following permission in your AndroidManifest.xml file:
"`xml
"`
Step 2: Write code to fetch the SIM number
In your Java or Kotlin code, you can use the TelephonyManager class to retrieve the SIM number. Here’s an example in Java:
"`java
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
if (telephonyManager != null) {
if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED) {
String simNumber = telephonyManager.getSimSerialNumber();
if (simNumber != null && !simNumber.isEmpty()) {
// You have successfully obtained the SIM number
// You can now use it as per your requirements
} else {
// SIM number is not available or empty
}
} else {
// Permission to read phone state is not granted
// You can request the permission from the user at this point
}
}
"`
Alternatively, if you’re using Kotlin, the code would look like this:
"`kotlin
val telephonyManager = getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager
if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED) {
val simNumber = telephonyManager.simSerialNumber
if (!simNumber.isNullOrEmpty()) {
// You have successfully obtained the SIM number
// You can now use it as per your requirements
} else {
// SIM number is not available or empty
}
} else {
// Permission to read phone state is not granted
// You can request the permission from the user at this point
}
"`
Remember to handle permissions and error scenarios as per your application’s logic and requirements.
It’s important to note that accessing the SIM number may not be available on all Android devices, as it is dependent on hardware and software configurations. Additionally, it’s crucial to handle user privacy and secure the obtained information in an appropriate manner.
