Product overview
Rugged essentials. The sealed body can be submerged and shrugs off drops, and the battery is replaceable, which is why a screwdriver is included in the box. Backlit keys and a simple menu keep the phone usable with cold hands or in poor light.
Connectivity and power. The Rock LTE runs on a Unisoc T127 platform with 4G LTE and VoLTE, 3G and 2G fallback, Bluetooth 5.1, a 3.5 mm headphone jack and a separate microSD slot for cards up to 64 GB. The 3000 mAh battery gives up to 384 hours of standby or 8 hours of talk time according to the manufacturer, and charges over USB-C (power adapter not included). A 2 MP camera with flash is built in.
