get phone number from sim card with telephonymanager

Question

I want to know that how I can get actual phone number from sim card instead of sim serial number.I have also tried (manager.getLine1Number) but it is giving me null.

Answer 1

A null reference might indicate that the phone number can not be accessed.

Documentation:

Note that access to some telephony information is permission-protected. Your application cannot access the protected information unless it has the appropriate permissions declared in its manifest file. Where permissions apply, they are noted in the the methods through which you access the protected information.

Required permissions:

READ_PHONE_STATE, READ_SMS, READ_PHONE_NUMBERS link to method doc

I have also found another question facing a quite similar issue "not working" with the method you named. Someone mentioned a duplicate question there, too. This could also be helpful: Link

If the code there is not helping you, I would recommend checking the exact documentation of your method to find details, why the null reference has been returned.

Answer 2

Ref: How to get the mobile number of current sim card in real device?

TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE); 
String number = tm.getLine1Number();

The documentation for getLine1Number() says this method will return null if the number is "unavailable", but it does not say when the number might be unavailable.

You'll need to give your application permission to make this query by adding the following to your Manifest:

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

(You shouldn't use TelephonyManager.getDefault() to get the TelephonyManager as that is a private undocumented API call and may change in future.)

OR

Ref: TelephonyManager give me null

> getLine1Number(); returns whatever is stored on the SIM card's MSISDN,
> which isn't filled by some operators.

In your case i am pretty much sure The MSISDN is unfilled.

You should keep one thing in mind.

getLine1Number() sometimes return with null value or with the phone number originally stored in SIM card.
