The XP 3400 Armor™ features a combination of hardened rubber molded into a reinforced fiberglass casing to give users the confidence to truly take the device anywhere.  The phone is certified against salt, fog, humidity, transport shock, thermal shock and operates in temperatures ranging from -5° F to 130° F. 

“This strategic partnership with C Spire brings Sonim’s legendary ruggedness to the nation’s first personalized network, meeting the growing demand among users for a reliable phone in the enterprise segment,” said Bob Plaschke, CEO of Sonim Technologies.  “The ultra-ruggedness of the Sonim XP 3400 Armor™ coupled with the dependability, reliability and coverage of the C Spire network make this a must-have device for workers in demanding jobs within the enterprise.”

With the XP 3400 Armor™, companies with mobile workforces can 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 superior signal sensitivity.  With up to 9.5 hours of talk time or 850 hours of standby time, the XP 3400 Armor has the power to handle long work days.
