I just got off chat with Sprint rep. I’m an existing customer with Sprint for about an year. I saw that Sprint was offering HULU on their website. I asked the rep if I can be eligible for it and she sent me a link for it. One HULU account per account (meaning 1 account per family plan) but she did say you can share credentials with the other phone lines in the account.
