The device comes under the model number Sonim XP3400, thus it's likely a CDMA version of the Sonim XP3300 Force, the handset with the world's longest talk time, so it should carry its 2" Gorilla Glass display, FM radio, GPS, and battery which provides 24 hours of talk time and 800 hours of standby times. A microSD card up to 8GB is supported in the XP3400, says the manual. Actually, the only difference between the Sonim XP3300, and the XP3400 we spotted at the FCC, seems to be the CDMA frequencies of the latter.
As any self-respecting Sonim phone, it also withstands dust, shock, vibration, extreme temperatures, and water. The Sonim XP3400 is tough as a nail, since the FCC photos of its back show the IP-68 seal of ruggedness approval, which means you can immerse it in water continuously for it's hermetically sealed. The manual actually says it can go up to 6 feet (2m), and stay there for 30 minutes without being damaged.
There is also a 2MP camera on the back with LED flash, which doubles as a torch. The camera does video recording as well, and there seem to be dedicated torch and browser buttons on the sides of the phone. The Sonim XP3400 comes with the hefty 3 years of warranty and... a screwdriver, should you wish to change the battery.
