How to auto import vcf file to android and iOS device from website button

In website, I have a anchor link for the vcf file. In android it downloads the file and then manually in need to save it. In Iphone it open directly but not auto imported the contact. Is there is any option to autosave the .vcf file to the mobile contact.

HTML Code

    <div class=button>
        <a href="<?php echo $base_url?>bcard/hamzeh.vcf">Add to Contact</a>
    </div>

.VCF File

BEGIN:VCARD

item1.URL;type=pref:https://test.com
item1.X-ABLabel:Website
item2.ADR;type=Office: #1, 1st St, Test location

END:VCARD

Expected result - The .vcf should be autosaved to the mobile contact.
