Not sure about the Castillo, but you can .....
Combine an IPTV Service provider
https://www.geeksforgeeks.org/best-iptv ... criptions/ ($10/mo to 50/yr, single connection.)
with an iOS or Android client
such as PerfectIPTV ($20 lifetime)
Most options have short, no or low cost trials so you can sample several. Be aware that these services can take 24 to 48 hours to activate, so plan ahead of your favored events. Providers sometimes get shut down, so use caution with yearly contracts. During the NFL playoff season, I will typically set up at least one shadow account for one month (about $10).
The provider I use offers 167 ABC, 167-CBS, 176-Fox, 194- NBC affiliates along with all the sports channels including ESPN U. It also provides foreign channels so you can watch events from Scottish Futbol (go Hearts!) to Albanian RTV Fontana (music videos, but don't expect any Dua Lipa). I also get access to thousands of Video-on-Demand TV Series and Movies. No VPN required, but I use one for anonymity.
I use an iPAD mini and cast content to my TV. I use that iPad with a cloud backup service so that I can back it up to the cloud and reset it periodically or before taking it through customs. I use this iPAD exclusively for hobby and related content. Nothing is associated with my real identity or even CRT handle.
