Android How to get phone number from Dual sim phone

Question

Hi, friends in my application, I want to show the user their phone number on the SIM card, but using a mobile phone with two SIM cards does not indicate the number of any number, I search a lot on Google, but I do not get exact.please help meto get phone number from dual sim. Note the following does not work on dual sim to get the number:

       String phonenumber = telephonymanager.getLine1Number();

Answer 1

telephonymanager.getLine1Number() It does not guarantee the return of the Sim number, since the phone number is not physically stored on all SIM-cards.

The best alternative is to ask the user for a phone number once and confirm it by sending a message to this number.
