I don't know anything about FastFish, but you might want to give hrsj800.com a try.
Did anyone else notice on hrsj800.com site, there's a new bottom banner "Premium English Version APK is launching Now. 500+ premium HD channels" that links to https://www.fasthdtv.com/? 5 day trial, 1 year service costs more, no lifetime offer. Is it the same service, just with English channel names?
