Sonim Technologies Launches New XP3plus Ultra-Rugged Flip Phone

Popular, Affordable, Phone Gets Upgraded and Delivers Simple, Fast and Reliable Communications

Austin, TX (Sept. 13, 2021) — Sonim Technologies (Nasdaq: SONM) announced today the launch of the XP3plus flip phone, now available at T-Mobile. 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.

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. For construction, field service, first responders, transportation and logistics workers who are constantly on the go, the XP3plus is compatible with a wide range of industrial-grade accessories including headsets, remote speaker microphones, vehicle mounts and more.

“There’s a large base of frontline and field workers who need reliable, durable and simple communications, and for the last two years the XP3 rugged flip phone has met those needs to become Sonim’s highest volume product,” said John Graff, Sonim chief marketing officer. “Now we are building on the tremendous customer feedback to further improve the performance, usability and simplicity with the introduction of the XP3plus available at T-Mobile.”

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 prevents the cost of device replacement. To see the XP3plus in action, click here.
