T-Mobile is reportedly in talks with Facebook to bring the social media site on board as its next Binge On partner.

According to a report from Recode’s Ina Fried, T-Mobile and Facebook have been working for some time on a plan to add Facebook video to Binge On.

In order to add a new partner to Binge On, though, video services must make certain technical tweaks to make sure their streams can be identified by T-Mobile’s system. That technical work is still ongoing with Facebook, the Recode report said.

T-Mobile and Facebook are also reportedly looking into offering a version of the social media giant’s Free Basics program, which allows users to browse certain parts of the Internet for free. Though the companies have been mum on this front, some T-Mobile users in March reported encountering a “Free data” message when using the Facebook app.

The addition of Facebook to Binge On would mark another big win for T-Mobile, which initially faced pushback on Binge On after it was launched last year.

In November, Binge On launched with 22 video partners, including HBO, Hulu, Netflix and Sling TV. Notably absent from the list, however, was Internet video giant YouTube.

T-Mobile finally managed to woo YouTube, adding it to Binge On in March after agreeing to address some of Google’s concerns about how Binge On treats services that are not included in the “free streaming” portion of the program and how users could exercise control over the Binge On’s options.

Earlier this week, T-Mobile announced its sixth expansion of Binge On. The Un-carrier said the service now has nearly 90 video partners.
