This offer is open to both new and existing Box users. Even if you already have the Android app installed on your phone, grabbing the update will automatically bump you up to a generous 50GB of free cloud storage.
50GB of storage in a Personal level Box account would normally cost $19.99/mo.. However, you’re still stuck with the 100MB maximum file upload size. In short, you might be hard-pressed to put those 50 gigs to good use.
Still, it might be worth trying to talk your Dropbox-using friends and colleagues into making the switch.
