Industrial Workers Benefit from Cellular and Radio-like Capabilities in One Rugged Device

Austin, Texas--(Newsfile Corp. - August 29, 2022) - Sonim Technologies (NASDAQ: SONM) today announced the availability of the XP5plus in Canada through a major carrier. The XP5plus builds on the legacy of its predecessor, the XP5s, one of the most widely used PTT-over-Cellular ultra-rugged devices among industrial workers who need instant reliable two-way communications when it matters most.

The new XP5plus is purpose-built for critical communications and includes features that enhance the Push-to-Talk (PTT) experience including a version of the device with two easy-to-use control knobs - for channel select and volume control. PTT can now be accessed without users ever taking their eyes off the mission in front of them.

With longer battery life and a larger screen, the XP5plus raises the bar on what a communication device can do. Third-party tested and validated to MIL-STD-810H, the XP5plus is drop proof and waterproof and will thrive in the most punishing conditions. Sonim is long recognized for the superior audio quality built into all its devices. The XP5plus does not disappoint with Goodix echo and noise cancellation technology built into the new 100dB+ speakers, which is loud enough to be heard in the noisiest conditions.

"We are pleased to continue to expand on Sonim's portfolio of mobile devices in the Canadian market," said Sonim CEO, Peter Liu. "It's our mission to equip users who work and play in some of the most extreme conditions in the world with ultra-rugged, user-friendly communications they can rely on day in and day out."
