San Diego, California--(Newsfile Corp. - March 21, 2024) - Sonim Technologies (NASDAQ: SONM) today announced that its new next-generation flagship 5G rugged phone has been selected by four leading carriers in North America for launch later this year. These most recent awards continue Sonim's growing momentum since commencing a strategic expansion in late 2023 and diversifying its product lines into new markets.

These most recent customer awards represent a significant milestone, securing now a total of 13 carrier slots for Sonim's upcoming 5G portfolio of rugged phones and wireless internet solutions, which underscores sustained growth and the market's confidence in Sonim's innovative products.

As a key part of the company's strategic portfolio expansion announced last year, this new 5G flagship phone, powered by the Snapdragon® 7 Gen 3 Mobile Platform, merges unprecedented design innovation with Sonim's hallmark quality and durability standards. This anticipated phone promises superior connectivity, thanks to Qualcomm Technologies' advanced 5G solution providing fast and reliable connectivity, resilience, and performance for users facing the toughest challenges in their work environments.

Chuck Becher, Chief Commercial Officer at Sonim Technologies, commented on the achievement: "The continued recognition of Sonim's expanding 5G portfolio from top-tier carriers is incredibly exciting for us. It validates our strategy of combining innovative rugged design with the unwavering quality that Sonim is known for. These additional carrier awards represent Sonim's strengthened foothold in the rugged mobile market and are a clear indication of our team's dedication and hard work coming to fruition."

Industry experts have also recognized Sonim's strategic direction and execution. Bryan Bassett, a research manager at IDC, remarked: "The fact that Sonim has secured these additional carrier wins is a significant endorsement of their new 5G rugged phone lineup. Sonim is not just maintaining its place in the rugged device market; it is actively advancing the standards of what these devices can achieve in terms of durability and functionality."
