Sonim XP3300 Force

“The Sonim XP3300 Force is the toughest cell phone we have ever reviewed. Not only that, it has the longest talk time of any phone we've ever reviewed: a whopping 22 hours and 29 minutes. It also has the best warranty out there: a three-year comprehensive policy that even covers accidental damage. And Sonim plans to update the phone with enterprise resource management apps, which could add some utility. Those things combined make this phone our Editor's Choice as the ultimate rugged phone. It's also one of The Best Unlocked Phones.”

“It's hard not to be impressed by a phone you can submerge in 6.5 feet of water for half an hour without it drowning, drop into antifreeze, and break out of a block of concrete without it sustaining damage. This is exactly the rough-and-tumble toughness that spurs rugged-phone maker Sonim Technologies along in its quest to outfit construction workers and others in outdoorsy occupations with cell phones sturdy enough to withstand a range of environmental hazards. Its latest effort, the Sonim XP3300 Force, has the same military specifications for powering through shock, dust, extreme temperatures, pressure, oil spills.”
