Hello friends in my app i want to show user to their sim phone number but with in dual sim mobile is not give any type number i much googling but not get exact.please help meto get phone number from dual sim. Note following is not working on dual sim to get number:
String phonenumber = telephonymanager.getLine1Number();
telephonymanager.getLine1Number()
does not guarantee to return the Sim number, as the phone number is not physically stored on all Sim cards.
A better alternative is to ask the user for the phone number once, and confirm the same by sending a message to that number.
Here is a better explanation for the same.
