Sonim Technologies Announces XP3plus Ultra-Rugged Flip Phone Award with Major U.S. Carrier

Austin, Texas--(Newsfile Corp. - August 25, 2022) - Sonim Technologies (NASDAQ: SONM) announced today a new award for the XP3plus flip phone with a major U.S. carrier. The new Sonim XP3plus builds on the legacy of its ultra-rugged, and very popular, predecessor, the XP3, to deliver enhanced capabilities for those who work in demanding environments and need simple, fast and reliable voice communications.

"Just as the XP3 was Sonim's highest volume product in recent history, with this new product award and partnership, the XP3plus is on the same trajectory," said Peter Liu, Sonim chief executive officer. "Popular among construction, field service, first responders, transportation and logistics workers who are constantly on the go, we anticipate the XP3plus will be the most widely available rugged flip phone in North America by 2023."

The XP3plus features a larger display, additional programmable buttons to improve productivity, and a new intuitive user interface with dynamic soft keys. A larger battery, strongest in its class, offers performance that will last extra shifts. Large, tactile and glove-friendly PTT and Emergency/SOS buttons offer instant mistake-free communication when it matters most. The XP3plus is compatible with a wide range of industrial-grade accessories including headsets, remote speaker microphones, vehicle mounts and more.

This compact flip phone meets Sonim's Rugged Performance Standards (RPS). Based on more than ten years of feedback from customer usage in the world's most extreme environments, Sonim Rugged Performance Standards consist of 12 benchmarks of endurance and durability and reassure Sonim customers at work or play. The XP3plus is drop proof and waterproof. It can withstand drops from 1.5 meters onto concrete and be submerged in 1.5 meters of water for 30 minutes. Audio quality in Sonim devices is superior and the XP3plus is no exception. The 100dB+ ultra-loud and clear audio speaker with noise-cancellation is loud enough to be heard in the noisiest construction site, manufacturing floor or family gathering. The flip phone comes with Sonim's industry-leading 3 year comprehensive warranty that practically eliminates the cost of device replacement due to breakage.
