With the usage that i normally see during the month, it wouldn't be cost effective to me, because my data overages would exceed (or at least come close) to the cost of home internet. If you don't use that much data, it may work for you...but keep in mind that data is used across a pretty large spectrum of activities (not just internet usage)...games, apps, updates, internet browsing, messaging, emails, etc...this all uses data (in my case, A LOT of data).
