The Good The Sonim XP3 is extremely rugged and durable. It offers GPS support and decent call quality.
The Bad The Sonim XP3 lacks multimedia messaging. Speakerphone calls were average.
The Bottom Line We're astounded by the lack of multimedia messaging, but the Sonim XP3 Quest should withstand most torture tests.
Sonim XP3 Quest (unlocked)
The Sonim XP3 Quest is the update to the Sonim XP1 that we reviewed last year. If you thought the XP1 was strong--and believe us when we say that it was--the XP3 goes a step further by being completely waterproof like the G'zOne handsets. If that isn't enough, the XP3 is certified to military specifications for salt, fog, humidity, shock, and vibration. You can use the XP3 as a hammer, store it in freezer (its operational temperature range is minus 4 to 131 degrees Fahrenheit), put it in a vice, and drop it on a concrete floor. We tried a few of these tests and the XP3 didn't get a scratch. You can check a full range of torture tests and its rugged specifications on Sonim's Web site.
Inside the phone you'll find midrange features that include a 2-megapixel camera, an FM radio, Bluetooth, and GPS with turn-by-turn directions. It also comes with a bright flashlight for use in all those extreme situations, but we're annoyed that there's no multimedia messaging. The sound quality is satisfying and the controls show improvement over the XP1. As the GSM handset is only available unlocked, it won't come cheap ($399) but that's the price you pay for the pleasure of throwing your phone against the wall when it drops your call.
