This is the ATT model of the SONIM XP6, the rugged smartphone with numeric keypad. Basically, XP6 is an Android-powered device, so don't get me wrong to call it a rugged smartphone. However, it’s also an old-model cell phone with typical numeric keypad, or may be more appropriate to see it as a cell phone with smart brain in an old body. Moreover, it did not seem appropriate also refer to the keypad as an old-style, because the fact is, the most comfortable tool to write short messages is via keypad , and clear up the current 'old style' it still has many fans.
Back to Sonim XP6 ATT model (there are another XP6 model, XP6 band 14 model and one other model), it is equipped with other features as well as ordinary smartphones. But it seems that, although it can be a touchscreen, 2.6-inch screen size is definitely not designed for touch screen technology. So, the only way to control is via the keypad. This obviously does not solve the problem, if the use is like usually smartphone. Outdoor workers would say a different course. As long as it is able to PTT and shock-resistant, the problem goes away.
As written above, Sonim XP6 also equipped with Android in general, including main camera, FM radio, WiFi tether, 3G connections via HSDPA up to 4G connectivity via LTE or HSPA + network. Meanwhile, unusual features including a series of certification relating to its status as a rugged cell phone and its huge battery capacity. Capacity of 5000 mAh battery which is almost, can last up to 3 days more talk-time and stand-by time up to one month and a half.
