The partnership between Facebook and Opera Mini offered several benefits for both parties. For Facebook, the collaboration enabled the company to expand its user base by providing a fast and accessible experience for mobile users. Opera Mini users benefited from a streamlined and user-friendly interface, which made it easier to navigate Facebook on their mobile devices. The partnership also facilitated the growth of mobile internet usage, as Opera Mini's data compression technology made it possible for users to access Facebook and other websites on limited data plans.

The browser's popularity soared, and by 2010, it had become one of the most widely used mobile browsers globally.

The integration touches upon the controversial "Zero-Rating" debate, famously highlighted by Facebook’s "Free Basics" program.
