Switch to AT&T for Free HBO
Switch to AT&T if you want free HBO. If you need an Unlimited data plan with all the features that AT&T offers, you may as well get free HBO with the service.
With the AT&T Unlimited Plus plan, you get a lot of added speed and features that you don't get with Choice. You also get free HBO, which is close to an $18 value.
If you have DirecTV or U-Verse, you get HBO through that service. If you only have a phone or use DirecTV Now, you get HBO through one of those services.
The timing is right as you prep for Game of Thrones Season 7.
