Mozilla announced Sunday that it will begin making $25 phones in a chip deal with Spreadtrum.

The company made the announcement in a press release before the kick-off of the Mobile World Congress in Barcelona.

Mozilla, a non-profit, will be turning to mobile OS with smartphone capabilities with a focus on developing markets and global carriers looking for a third option, Forbes reported.

Mozilla launched its Mobile OS in 2012. Then Chinese manufacturer ZTE announced it would collaborate with the company on an open software-based device.

“It’s all part of our wider plans to create a better balance of products using various operating systems. We won’t just rely on Android or Windows,” said ZTE Director of Corporate Branding & Communications David Dai Shu.

Firefox OS is slated to move into Argentina, Costa Rica, Ecuador, El Salvador, Germany, Guatemala, Nicaragua and Panama this year as Telefonica expands to those countries. Deutsche Telekom will contribute markets in Croatia, the Czech Republic, Macedonia and Montenegro.

While Windows has targeted the lower-end of the mobile market, Mozilla may be emerge the victorious underdog, according to Forbes.
