Seems to me that Gigasurf gives you 1GB++ that you can use up to 3 days. If you use up the 1GB before the 3rd day then that's it, promo's over.

Hey, doesn't Globe start throttling mobile data once you reach 800MB? Maybe the 1GB/day is "immune" to that?

Anyway, I agree it doesn't really make sense to use the 1GB/day. I guess they're too lazy to keep track of promos that are redundant. No wonder there are bugs in Gosakto. They're not even patching it up it seems.
