CONX Corporation said Monday it acquired a controlling stake in MobileX, a wireless service provider based in Orange County, California, for an undisclosed sum.
The transaction adds Charlie Ergen, founder and chairman of EchoStar, who also serves as CONX’s chairman, to MobileX’s board of directors. CONX chief executive Jason Kiser will also join the board as part of the deal.
MobileX offers customizable wireless plans starting at $3.88 per month, excluding taxes and government surcharges, and uses artificial intelligence to tailor plans based on customer usage. The service is accessible via iOS and Android apps, online, and through approximately 3,700 Walmart stores and 5,000 independent dealer locations nationwide.
The investment will fund customer acquisition, expand dealer and retail distribution, and support development of the AI-driven platform. CONX also plans to explore opportunities in global connectivity and AI-enabled wireless services, according to the company.
Peter Adderton, MobileX founder and chief executive, said the partnership aligns with the company’s vision and provides capital to scale operations and compete more broadly.
