While standard Hulu service will work on a cellular device, Hulu Live is their live TV service that uses your IP Address to show you local programming. Since your service is cellular-based, the IP address changes often which causes Hulu Live to kick out the connection. We feel like they need to change their system to a more modern approach and not punish rural area users that use cellular and satellite for Internet communications.
We welcome you to call Hulu at (888) 265-6650 to let them know you want to be able to use their Hulu Live with your cellular or satellite service.
Other live tv streaming services like Youtube TV, Sling, and Philio work on cellular connections.
