Things are rather straight forward for new customers as what they need to do is just register for a new package. As for existing customers, it is not exactly complicated since they just need to renew their contract in order to obtain the free Internet until the end of this year but we do know some customers would rather keep their out-of-contract status intact.
Meanwhile, not unifi package are eligible for the new Pay Nothing promo though. Among the packages that are excluded from this promo include the unifi Basic 60GB, unifi Lite, and unifi Air. Also do note that unifi Mobile as well as CCTV add-on, Video On Demand, call usages, and one time charges are being excluded too. (Source: unifi.)
