Library fetches phone contacts only

[hasnabbas]

I am trying to get contact name using phone number but it returns null when the contact is in sim.

This is my code:

          fun getContactName(phone: String): String{
             val query = Contacts.getQuery()
             query.whereEqualTo(Contact.Field.PhoneNumber, phone)
             val contacts = query.find()
             return if (contacts.isNotEmpty())
                 contacts[0].displayName

             else
                 ""
         }
