WIZ is Globe's name for its wifi hotspots. It is short for Wireless Internet Zone.
If I understood it correctly, when you subscribe to a promo, you would be able to enjoy Unlimited Viber Chat (no extra data charges just for Viber chat) in your phone during the validity of that subscription.

Thanks. I just clarify my posts. The WiZ and The Unli Viber Promos had been ADDED to the list of Promos on *143# (i forgot to type it. TYPO ERROR!!)
So i get the point from Unli Viber Promo. But im still confusing to the WiZ Promo.I saw choices from WiZ How,WiZ Where etc.So, Can I request you sir to check *143# to see for yourself because i cant explain more about that. Just find on the "Surf Promo" list. Thanks! :-)
Anyway, i will also ask @Talk2Globe on twitter abt this promo. Thanks again sir ChitoReyes
