The Ukrainian company Sigma mobile, which specializes mainly in secure devices, introduced a new armor-piercing button.
Model Sigma mobile X-treme ST68 has protection againstwater and dust class IP68. Protection against falls is not specified, but the design clearly assumes that if without fanaticism, then you can drop it, nothing will happen to it. The presence of the SOS key, located on the back of the phone, allows you to make alternate calls and send SMS messages to four pre-programmed subscribers in case of an emergency. This is useful not only for a lonely tourist who has got into trouble far from civilization, but for elderly people, so the device can be considered as a grandmother's phone.
The battery for the button is very good - 2600 mAh. The screen is quite large - 2.8 ″. The camera is there, but foolish. Works only in GSM networks.
These are more or less standard features, butthere is an unusual one. Sigma mobile X-treme ST68 is perhaps the first button where the microUSB port was replaced with the modern Type-C. Another plus in the theme of “grandmother's” application - it is easier to get to such a port.
