Update  This answer is no longer available as Whatsapp had stopped exposing the phone number as account name  kindly disregard this answer   There is actually an alternative solution you might want to consider  if you can t get it through telephony service    As of today  you can rely on another big application Whatsapp  using AccountManager  Millions of devices have this application installed and if you can t get the phone number via TelephonyManager  you may give this a shot   Permission    lt uses-permission android name  android permission GET ACCOUNTS    gt    Code   AccountManager am   AccountManager get this   Account   accounts   am getAccounts     for  Account ac   accounts        String acname   ac name      String actype   ac type         Take your time to look at all available accounts     System out println  Accounts       acname          actype       Check actype for WhatsApp account  if actype equals  com whatsapp         String phoneNumber   ac name      Of course you may not get it if user did not install WhatsApp  but its worth to try anyway  And remember you should always ask user for confirmation

Wouldn t be recommending to use TelephonyManager as it requires the app to require READ PHONE STATE permission during runtime   lt uses-permission android name  quot android permission READ PHONE STATE quot   gt    Should be using Google s Play Service for Authentication  and it will able to allow User to select which phoneNumber to use  and handles multiple SIM cards  rather than us trying to guess which one is the primary SIM Card  implementation  quot com google android gms play-services-auth  play service auth version quot   fun main         val googleApiClient   GoogleApiClient Builder context           addApi Auth CREDENTIALS API  build        val hintRequest   HintRequest Builder            setPhoneNumberIdentifierSupported true           build        val hintPickerIntent   Auth CredentialsApi getHintPickerIntent          googleApiClient  hintRequest            startIntentSenderForResult          hintPickerIntent intentSender  REQUEST PHONE NUMBER  null  0  0  0          override fun onActivityResult requestCode  Int  resultCode  Int  data  Intent         super onActivityResult requestCode  resultCode  data      when  requestCode            REQUEST PHONE NUMBER - gt                if  requestCode    Activity RESULT OK                    val credential   data  getParcelableExtra lt Credential gt  Credential EXTRA KEY                  val selectedPhoneNumber   credential  id

There is a new Android api that allows the user to select their phonenumber without the need for a permission  Take a look at  https   android-developers googleblog com 2017 10 effective-phone-number-verification html     Construct a request for phone numbers and show the picker private void requestHint         HintRequest hintRequest   new HintRequest Builder           setPhoneNumberIdentifierSupported true          build         PendingIntent intent   Auth CredentialsApi getHintPickerIntent          apiClient  hintRequest       startIntentSenderForResult intent getIntentSender            RESOLVE HINT  null  0  0  0

while working on a security app which needed to get the phone number of who so ever my phone might get into their hands  I had to do this  1  receive Boot completed and then try getting Line1 Number from telephonyManager which returns a string result  2  compare the String result with my own phone number and if they don t match or string returns null then  3  secretly send an SMS containing the string result plus a special sign to my office number  4  if message sending fails  start a service and keep trying after each hour until sent SMS pending intent returns successful  With this steps I could get the number of the person using my lost phone   it doesn t matter if the person is charged

As posted in my earlier answer  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

First of all getting users mobile number is against the Ethical policy  earlier it was possible but now as per my research there no solid solution available for this  By using some code it is possible to get mobile number but no guarantee may be it will work only in few device  After lot of research i found only three solution but they are not working in all device   There is the following reason why we are not getting   1 Android device and new Sim Card not storing mobile number if mobile number is not available in device and in sim then how it is possible to get number  if any old sim card having mobile number then using Telephony manager we can get the number other wise it will return the    null    or        or                lt uses-permission android name  android permission READ PHONE STATE   gt    TelephonyManager tel   TelephonyManager this getSystemService Context              TELEPHONY SERVICE       String PhoneNumber    tel getLine1Number         Note - I have tested this solution in following device Moto x  Samsung Tab 4  Samsung S4  Nexus 5 and Redmi 2 prime but it doesn   t work every   time it return empty string so conclusion is it s useless    This method is working only in Redmi 2 prime  but for this need to add read contact permission in manifest       Note - This is also not the guaranteed and efficient solution  I have tested this solution in many device but it worked only in Redmi 2 prime   which is dual sim device it gives me two mobile number first one is   correct but the second one is not belong to my second sim it belong to   my some old sim card which i am not using     String main data       data1    is primary    data3    data2    data1                is primary    photo uri    mimetype        Object object   getContentResolver                query Uri withAppendedPath android provider ContactsContract Profile CONTENT URI   data                main data   mimetype                 new String    vnd android cursor item phone v2                 is primary DESC        String s1         if  object    null            do               if     Cursor   object   moveToNext                    break                 This is the phoneNumber              s1  s1  ---     Cursor   object   getString 4             while  true             Cursor   object   close             In my research i have found earlier it was possible to get mobile number using WhatsApp account but now new Whatsapp version doesn   t storing user s mobile number       Conclusion - Android doesn   t have any guaranteed solution to get   user s mobile number programmatically       Suggestion - 1  If you want to verify user   s mobile number then ask to   user to provide his number  using otp you can can verify that          If you want to identify the user   s device  for this you can easily get device IMEI number

Just want to add a bit here to above explanations in the above answers  Which will save time for others as well   In my case this method didn t returned any mobile number  an empty string was returned  It was due to the case that I had ported my number on the new sim  So if I go into the Settings About Phone Status My Phone Number it shows me  Unknown

Code   TelephonyManager tMgr    TelephonyManager mAppContext getSystemService Context TELEPHONY SERVICE   String mPhoneNumber   tMgr getLine1Number      Required Permission    lt uses-permission android name  android permission READ PHONE STATE   gt     Caveats   According to the highly upvoted comments  there are a few caveats to be aware of  This can return null or    or even            and it can return a stale phone number that is no longer valid  If you want something that uniquely identifies the device  you should use getDeviceId   instead

Sometimes  below code returns null or blank string   TelephonyManager tMgr    TelephonyManager mAppContext getSystemService Context TELEPHONY SERVICE   String mPhoneNumber   tMgr getLine1Number      With below permission   lt uses-permission android name  android permission READ PHONE STATE   gt    There is another way you will be able to get your phone number  I haven t tested this on multiple devices but above code is not working every time   Try below code   String main data       data1    is primary    data3    data2    data1    is primary    photo uri    mimetype    Object object   getContentResolver   query Uri withAppendedPath android provider ContactsContract Profile CONTENT URI   data            main data   mimetype             new String    vnd android cursor item phone v2             is primary DESC    if  object    null        do           if     Cursor   object   moveToNext                break             This is the phoneNumber         String s1     Cursor   object   getString 4         while  true         Cursor   object   close        You will need to add these two permissions    lt uses-permission android name  android permission READ CONTACTS    gt   lt uses-permission android name  android permission READ PROFILE    gt    Hope this helps  Thanks

There is no guaranteed solution to this problem because the phone number is not physically stored on all SIM-cards  or broadcasted from the network to the phone  This is especially true in some countries which requires physical address verification  with number assignment only happening afterwards  Phone number assignment happens on the network - and can be changed without changing the SIM card or device  e g  this is how porting is supported    I know it is pain  but most likely the best solution is just to ask the user to enter his her phone number once and store it

Although it s possible to have multiple voicemail accounts  when calling from your own number  carriers route you to voicemail  So  TelephonyManager getVoiceMailNumber   or TelephonyManager getCompleteVoiceMailNumber    depending on the flavor you need   Hope this helps

User · Answer

TelephonyManager is not the right solution  because in some cases the number is not stored in the SIM  I suggest that you should use the shared preference to store the user s phone number for the first time the application is open and the number will used whenever you need
