If you are a Dish Network subscriber and want to watch WrestleMania then your best bet would be to watch at a friends house or watch it on the WWE Network. It doesn’t look like they have plans on carrying pay-per-views in the near future, if ever. Subscribers that have asked about WrestleMania have been sent this reply by Dish:
Please note that WWE is not willing to adjust PPV costs to satellite/cable companies, which is unfair to their customers. DISH needs to re-focus efforts to support partners that better serve DISH customers and other satellite/cable companies, including DirecTV, have also expressed they may no longer provide WWE PPV events in the future.
There are other cable providers considering dropping WWE pay-per-views after WrestleMania.
