Visitors cannot contact Advertiser problem on real estate and classified themes

Premiumpress themes have this problem that visitors cannot contact advertisers directly.

Visitors have to use contact form instead of calling or sending sms to advertisers mobile handphone.

This is because such mobile handphone details if captured on registration page via customised fields are not displayed on individual listing page.

Can someone please help on this – to create a table that displayed customised fields results onto individual listing page? What is the coding to insert onto individual listing page?

This is a very basic feature for real estate or classified script but yet this is not available.
