Telecom is one of the world’s largest and most established industries, yet open source software still has limited presence in many of its core systems. Despite billions in annual revenue and thousands of mobile network operators (MNOs) and virtual operators (MVNOs), most rely on closed, proprietary solutions that limit flexibility and drive up long-term costs.

This gap creates a real opportunity. As networks become more complex and market demands grow, MNOs and MVNOs need software that adapts quickly, integrates easily, and offers full visibility and control. Open source solutions are built for this—removing vendor lock-in, reducing time-to-market, and enabling real collaboration between operators and developers.

At PAiCore, we build open source Core Technologies designed to support real telecom environments. Our solutions give operators full ownership of their stack while remaining compliant, scalable, and easy to integrate.

For MNOs, MVNOs, and system integrators, open source should be more than just a development choice—it should be a way to stay competitive, reduce 3rd party dependencies, improve margins and move forward with confidence.
