Getting SIM serial number in Android

I need to make sure the SIM card can be used without entering pin in designated device(s), but it must be required in other devices. (Devices in use are rooted, application is installed as system app)
What I want is to identify a SIM card, and enter the pin programmatically, if one is already known/saved.
I am able to enter the known pin code, when one is required, but I have a problem with SIM identification.
I found out that I am not able to get SIM serial number or subscriber id before the correct PIN is entered.
The method I am using (with permissions and etc.):
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.getSimSerialNumber();
The thing is, this method returns null, if pin is required and not yet entered.
My question is if there is some kind of workaround for this.
Is it possible at all?
Is there another approach?
Ideas and approaches appreciated.
Thanks in advance.

TelephonyManager tm = (TelephonyManager)
getSystemService(Context.TELEPHONY_SERVICE);
}
String simID = tm.getSimSerialNumber();
String telNumber = tm.getLine1Number();
String IMEI = tm.getDeviceId();
Permission:
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
Your issue:
The phone number returned is whatever is stored on the SIM card's MSISDN, which is not filled by some operators. Try Airtel, Vodafone if in India.

Get phone number ANDROID

I want get a phone number, but in device I get "" (empty). Any suggest?
This is my code:
TelephonyManager tMgr = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
String mPhoneNumber = tMgr.getLine1Number();
mPhoneNumber is empty.
Manifest has:
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

Some models return the phone number, some don't. I had the need for getting the phone number and ended up using Twitter's Fabric Digits. Easy to setup and free to use.

That API call is probing your sim card. Some telecom companies don't require the population of the phone number field in order to operate. So if your sim card doesn't have that information your string will be blank each time.

Get mobile Number on GSM Mobile using android code

I am using following android code to get mobile number and it's working on android emulators only:
TelephonyManager tm =(TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String number = tm.getLine1Number();
But when I tested it in real device (Samsung Galaxy Chat B5330) it gives nothing (Empty String)
Please help with some code snippet.

For GSM, the phone number is on the SIM card, and some carriers just don't put it on the card, and then the phone does not know what it is, but in this case you
should get an empry string rather than a null
if the carrier stores the number on your SIM, go to Settings -> About Phone -> Status -> My phone Number. If it displays unknown there, then your number is not stored on the SIM.
get IMEI use:
TelephonyManager tm =(TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
imei_no = tm.getDeviceId();

Add permission
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
See this

You have to use Telephony Manager;If at all you not found the contact no. of user;
You can get Sim Serial Number of Sim Card and Imei No. of Android Device by using the same Telephony Manager Class...
Add permission:
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
Import:
import android.telephony.TelephonyManager;
Use the below code:
TelephonyManager tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
// get IMEI
imei = tm.getDeviceId();
// get SimSerialNumber
simSerialNumber = tm.getSimSerialNumber();

Retrieve the number and IMEI of the mobile phone

I want to retrieve the own mobile number and the IMEI.
How do I get this information from the Android phone?

use
TelephonyManager tm = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
// get IMEI
String imei = tm.getDeviceId();
String phone = tm.getLine1Number();
but its not always reliable on for example non phone device.
and you should also add this following permission to your AndroidManifest.xml file
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

getLine1Number();
this method returns the phone number string for line 1,
i.e the MSISDN for a GSM phone. Return null if it is unavailable.
but what about CDMA phone?
Note : this method works only for few cell phone not for all devices
.

Obtaining the phone number and phone ID for a phone in android

everyone. I have to build an Android application and one requirement is to be able to record the phone number and the phone ID. Is there any to do this? Any help would be much appreciated.

May be TelephonyManager.getDeviceId()

Note that you can get the telephone number, but it's usually inaccurate information (whatever the user has entered manually in the settings, if anything).
This is the code to do it:
TelephonyManager tm;
String phoneNumber = tm.getLine1Number();
String IMEI = tm.getDeviceId();

Correct code :
TelephonyManager telManager;
telManager = (TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
telManager.getDeviceId();
