Hulu + Live TV subscribers can upgrade to Unlimited Streams for an additional $9.99 a month. The unlimited streams apply to devices within your home internet network. Unfortunately, you can only get three streams on mobile devices outside of your home network. Unlimited Streams is not available for Hulu subscriptions minus Live TV. The Unlimited Streams upgrade also doesn’t apply to add-on premium networks like HBO Max, CINEMAX, SHOWTIME, or STARZ. With them, you’ll be limited to five streams within your home network, and three on mobile devices outside of the network.
