Sonim Launches the XP3300 Force - a Mobile Phone With the Longest Talk Time in the World

Ultra-Rugged GSM Phone Designed for Mobile Resource Management (MRM) Applications in Vertical Industries

BARCELONA, Spain, February 14, 2011 - Mobile World Congress — Sonim Technologies today announces the Sonim
XP3300 FORCE (www.sonimtech.com/products/xp3300force.php) GSM mobile
phone, an ultra-rugged MRM-ready handset designed to help enterprises and
government organizations locate, track and manage mobile workers, their tasks
and assets. Built on lessons learned from serving half a million customers
with the toughest jobs on earth, some who work 16 hour shifts, Sonim's XP3300
FORCE helps maximize workforce efficiency, minimize downtime and enhance
safety in industries such as transportation, logistics and utilities.

"The XP3300 FORCE takes Sonim's legendary ruggedness to the enterprise
segment," said Bob Plaschke, CEO of Sonim Technologies. "There's no question
it's a power tool of communications. We continue to dream up new ways that
showcase how Sonim's handsets stretch the limits of phone engineering such
as:

    - submerging it in an antifreeze mixture
      (www.youtube.com/watch?v=aYbxs6CQJAk);
    - dropping it from 30 meters
      (www.youtube.com/watch?v=2zFhuJ2evvU);
    - casting it in concrete
      (news.bbc.co.uk/2/hi/programmes/click_online/9369639.stm)."

WORKFORCE EFFICIENCY

With the XP3300 FORCE, Sonim's objective is to help companies with mobile
workforces reduce operating costs, increase productivity, improve customer
satisfaction and ensure employee safety. The handset has professional-grade
Assisted GPS that delivers highly accurate locations and faster location
fixes due to the excellent signal sensitivity. With 20 to 24 hours of talk
time or GPS tracking time of up to 26 hours with MRM applications (at 5
minute location update intervals), the XP3300 FORCE has the power to work
through the long 16-hour shifts endured by Sonim users. The 2 MP camera with
a bright LED flash and digital zoom captures critical job site information.
Sonim has further improved the reliability, speed and available memory for
JAVA applications and the Sonim JAVA Application Manager (JAM) store will
offer a range of pre-tested and certified third party workforce management
applications for download. The handset is a quad band GSM unit with GPRS and
EDGE data capability.

The MRM applications being integrated with the Sonim XP3300 FORCE offer
workforce location monitoring, fleet tracking, monitoring, timecard
reporting, real-time work order updates, alerts, job scheduling, event
confirmation, data collection and reports. "Integration and field testing is
underway with some of the world's leading MRM application providers, who have
recognized the XP3300 FORCE as the ideal rugged MRM phone," said Sanjay
Jhawar, VP/GM of Marketing and Applications.

A software revision for the XP3300 will be released following final MRM
field-testing and the following will be commercially certified and available
in Q2 2011:

    - mComet from Actsoft: www.actsoft.com
    - Timecard from Econz Wireless: www.econz.com
    - Track & Trace from Spotmaster: www.spotmaster.com
    - TimeTrack from Xora: www.xora.com

Other applications for the XP3300 include an Opera Mini(R) browser and
City Cruiser(R) navigation. NoteVault, a voice note transcription and
project-reporting tool specifically for the construction industry, is also
available. Subscription fees will apply for NoteVault and MRM applications.

RUGGEDNESS TO MINIMIZE DOWNTIME

Sonim's Rugged Performance Standards Certified (RPS) surpass the military
specifications for ruggedness.

Even wastewater 2 meters deep is no challenge for this IP-68 rated, water
and dust proof handset, which can also be dropped from 2 meters onto
concrete. The 2 inch high-resolution display is protected by a class-leading
1.5 mm thick Corning(R) Gorilla(R) Glass lens for the highest scratch and
shock resistance. Sonim has added a fiberglass mix to the phone's housing to
give users the confidence to truly take it anywhere. The phone is certified
against salt, fog, humidity, transport shock, and thermal shock and operates
in temperatures ranging from -20 degrees C to +55 degrees C.

SAFETY

The Sonim XP3300 FORCE enhances the worker's safety by enabling calls
under the worst conditions. The phone features strong antenna performance,
the industry's longest talk time of 20 to 24 hours and 800 hours of standby
time, an active noise canceling microphone, and loud audio with a 23mm
speaker, protected by a GORE(R) protective vent. Enhanced usability with
widely-spaced keys for ease of use with gloved hands and a higher resolution
display with good outdoor visibility also contribute to dependability that
saves lives.

Rugged and reliable, the XP3300 FORCE is backed by Sonim's 3-Year
Comprehensive Warranty.
