@Miss-TinaWhy don't you directly ask the rumour-monger guy who's spreading this news??
Last year in Pak, there was some rumour that WARID TEL was offering free internet to some users having special WARID SIMs. But there was no truth at all. And i doubt same is the case with ZOnG....
Anyhow i'm not sure but check the following forums. Could be helpful for you.
