Despite the rapid development of the smartphone market, fans of feature phones have by no means died out. Most often they are chosen by the elderly, unpretentious users and people who do not need a pocket super-computer, but a simple dialer that does not require constant charging. It is for these categories of customers that X-style feature phones from Sigma mobile are designed.


Most X-style handsets are classic entry-level push-button telephones with a minimum of bells and whistles. Their capabilities are usually limited to a flashlight, an FM receiver, a primitive camera, a memory card slot and an optional second SIM tray. A simple display, as a rule, does not impress with its dimensions and quality; it is needed solely for displaying system information. Most models have LCD screens with a diagonal of 2.4-3.5 inches and a pixel density in the region of 150-160 ppi. In addition to them, X-style phones with a monochrome display are occasionally on sale.

At the same time, X-style phones do not need to be constantly charged, the displays here do not fade in the sun, endless push notifications do not distract from everyday life, and in the event of a breakdown or loss, the owner does not have to bite his elbows. The average price in this line does not exceed $40, and some samples can even be purchased for $15-17, which is cheaper than many cases, chargers, wireless headphones and other peripherals for smartphones.
