As Answered here  Use below code    TelephonyManager tMgr    TelephonyManager mAppContext getSystemService Context TELEPHONY SERVICE   String mPhoneNumber   tMgr getLine1Number      In AndroidManifest xml  give the following permission     lt uses-permission android name  android permission READ PHONE STATE   gt     But remember  this code does not always work  since Cell phone number is dependent on the SIM Card and the Network operator   Cell phone carrier   Also  try checking in Phone--  Settings --  About --  Phone Identity  If you are able to view the Number there  the probability of getting the phone number from above code is higher  If you are not able to view the phone number in the settings  then you won t be able to get via this code   Suggested Workaround    Get the user s phone number as manual input from the user  Send a code to the user s mobile number via SMS  Ask user to enter the code to confirm the phone number  Save the number in sharedpreference    Do the above 4 steps as one time activity during the app s first launch  Later on  whenever phone number is required  use the value available in shared preference

From the documentation      Returns the phone number string for line 1  for example  the MSISDN for a GSM phone  Return null if it is unavailable    So you have done everything right  but there is no phone number stored   If you get null  you could display something to get the user to input the phone number on his her own

If the function you called returns null  it means your phone number is not registered in your contact list   If instead of the phone number you just need an unique number  you may use the sim card s serial number       TelephonyManager telemamanger    TelephonyManager getSystemService Context TELEPHONY SERVICE       String getSimSerialNumber   telemamanger getSimSerialNumber
