Two slots available for Youtube TV $25 per month, Month to Month. $20 per month if you prepay for three months.
They cut off your service after 3 months if you're not located in the same area.
I should clarify, they cut off service outside of the primary's home region. Out of region you get a message saying to go back home or update your new home address. They don't allow multiple locations on the same account after 3 months time.
