AT&T U-verse and DirecTV Free Channel Previews Dec 7-13, 2020 (from FREEPREVIEW.tv)
AT&T is offering free previews of EPIX now thru December 13th.
I noticed it myself (U-verse), and then found reference to it at https://www.freepreview.tv/free-preview-of-epix-and-movies-extra-pack-3536 (DirecTV).
Not sure if this applies to AT&T TV or not.
Channels will vary based on which service you have.
