![]() |
A simple and concise push-button "tube" with the so-called elongated screen. It's no joke, its diagonal dimensions are 3.5", which is by no means a lot by the standards of ordinary "dialers". The picture is displayed on the phone display at a resolution of 480x320 pixels. Support for two SIM-cards allows you to choose the most favorable rates for calls to numbers of different mobile operators, as well as separate personal and business calls.
Afterwards, the Sigma X-style 351 LIDER has a separate slot for a microSD memory expansion card (up to 32 GB inclusive). The model has a modest 0.3 MP camera, a bright flashlight, an FM radio, and a Bluetooth wireless module (for connecting accessories in the manner of wireless headphones). Finally, the energy core of the device is a capacious 3400 mAh battery, which provides a long battery life without recharging (up to two weeks in a row in standby mode).

It seems that people have forgotten how to make ordinary phones and reinvent the wheel. But everything has long been invented and thought out by pioneers in the face of nokia, siemens and others. In general, for such money the phone is more or less tolerable. Relatively large screen, loud speaker, normal battery, flashlight. It would be possible to make the dimensions smaller while retaining everything else. The device feels empty. The space on the screen is not very correctly distributed, some of the text is very small, not well thought out or rather made to work. Minimum settings. Neither reassign nor make the camera available for quick access, for example. Disgusting melodies by default. Different formats of places for sim cards. In addition, there is no space on the phone at all. That is, without a memory card, not a single photo can be saved. ![]() |
I bought the phone at COMFY. After inserting the SIM card, I discovered that during outgoing calls, the screen flickers, as if something inside wasn't soldered properly. Also, the SIM card started disconnecting periodically in one of the slots. Replacing it with another SIM card didn't solve the problem. A third defect of the phone is that during incoming calls, the labels on the icons representing functions started to go beyond their fields. It seems like a flawed firmware. I do not recommend buying this phone, it's very problematic. The manufacturer needs to fix the errors and enhance quality control before selling. Hats off to the service center staff on Petrovka. After submitting the phone for warranty repair, they fixed it in three days. Let's see how it will work from now on. Battery A bunch of flaws |
Against the background of hordes of colleagues in the shop push-button "tubes" Sigma mobile X-style 351 LIDER stands out with one notable feature - an increased caliber of a color display. And this is by no means the only interesting feature of the character of the device.
big screen
The model was equipped with a large 3.5-inch diagonal screen with a resolution of the broadcast image of 480x320 pixels. The display holds more useful information and captivates with good readability. But the protective plastic on top of the screen raises questions - in the reviews of the phone there are complaints about its deflection at the slightest touch. Also too fragile is the body of the device.
Long autonomy
Under the hood, the Sigma mobile X-style 351 LIDER has a powerful 3400 mAh battery. One charge of the battery is enough for about two weeks of productive work of the device. The battery is charged through the contact group of the microUSB connector. At the same time, the "inside" of the model hides two SIM slots and a microSD card slot. The drive will come in handy for storing photos taken with a 0.3 MP camera and music tracks. You can listen to music from your phone through Bluetooth headphones.
Additional equipment
A full-fledged flashlight, an FM radio receiver and a notebook for 500 contacts got into the additional disposal of the phone - a standard set for a “button”. Of the negative factors, the models note a high percentage of marriage - users often face the problem of a flickering screen and the failure of one of the SIM cards. However, the manufacturer always listens to the user audience and repairs or replaces defective copies without any problems.
Ukrainian brand Sigma mobile was established in 2010 by a team of specialists in the field of IT technology, telephony, and radio communication to develop and offer products that would meet the needs of IT technology and telephony users not considered in mass products.
