The unlimited data plan wars continue to heat up. AT&T has announced that customers of its Unlimited Plus wireless plan who also subscribe to AT&T-owned TV services like DirecTV, DirecTV Now, and U-Verse will also get HBO for free. In addition, streaming HBO will not count against the 22 GB soft bandwidth cap. Unlimited Plus customers will also receive a $25 per month credit toward the aforementioned TV services. If you live in an AT&T service area, that’s a sweet deal if you want unlimited mobile Internet, TV service, and HBO (which usually costs about $15 per month on its own).
