    This, Sigma Mobile X-treme IP67 Dual SIM did not just dust-water resistant, but also shock resistant. He can not be afraid to get into trouble, in addition, it is equipped with a battery as big as a capacity for non-smartphone, 1700 mA * h To understand whether there is life for ordinary phones and interestingly than the listed characteristics to offer Sigma IP67, we spent with him for a few weeks.

    Packaging and delivery

    The phone comes in a box of black color on the front where you can see the name of the device and the way it looks. On the left side of the printed specifications Sigma IP67, on the lower sidewall - an explanation of each of the degrees of protection: dust, shock and moisture.

    Inside the box we found the phone, battery, wired headset with a key answer calls, the network adapter to 0.5 A, USB-cable and clip to unscrew the mounting screws located on the rear panel. In addition, there is a complete instruction manual and warranty card.

    Design and ergonomics

    The model comes in four different colors - black, black and gray, black and orange (like us) and khaki. In our view, a device of this type should be as clearly as possible, so that if anything, it was easier to find.

    Sidewall material - rubber with a tread pattern in the form of Christmas trees. At the ends of the same material is used, but with a different pattern in the form of transverse notches. The removable

    Rear panel is made in the same style and color as the sides and ends of the housing. At its center is a great logo emblazoned Sigma mobile, and at the top on the edges - two hats screws. To remove the need to use the complete clip. Beneath it is the battery capacity of 1700 mAh, which is on the box, Ukrainian language applied introductory information. The battery has three slots for two SIM-cards and one card reader. In addition to the body of the phone has the volume keys, flashlight, camera, headphone jack and a data cable (covered with a plug).

    The phone weighs not too much, 140 grams, but its thickness is knocked out of the ordinary. Twenty millimeters felt very good. On the other hand, it gives the feeling of having something of value in his hand. Build quality is excellent. After a few falls, rolls in the snow and other tests, the case remains the same as that of the box.

    Phone features

    People who are used to broad capabilities of smart phones, it is not worth considering as an alternative Sigma IP67. The phone is quite modest. On the one hand, there are inherent attributes as the phonebook, messages, calendar, calculator, MP3 player and video player, voice recorder, FM-receiver, a photo and video camera, but on the other hand, expect them something more than

    Sigma  review

    For example, each cell phone book can store one number on the caller, and the transfer of contacts from another device via Bluetooth does not lead to the desired result, the phone does not like the format of the data. As a result, the contacts have to manually make or use as carrier SIM-card.

    Sigma  review

    The main menu of the phone is made in the form of a 3x3 matrix with animated icons. First place is "Call Log". It is followed by "Contacts", "File Manager", "organizer", "Messages", "Music", "browser", "camera" and "Settings". The phone supports Java-based applications, in view of its modest capabilities, can be considered as a plus.


    During the test, the ten days of active use, so we never once had to charge the phone battery. During this period, there were more than an hour of calls made and received about the same inbox. The total number of text messages or 35 pieces. Several times included camera and music player. Result unattainable for a smartphone.

    When connected to a PC, your phone has a memory card, the device is recognized as a removable drive. So to copy files to and from your phone is easy.

    A camera with a resolution of 1.3 MP means you can record video with a resolution of 320x240 pixels. The quality of photos and videos is low, in this respect, Sigma mobile X-treme IP67 wins any smartphone.

    Speaker volume, conversational and multimedia, high. It is unlikely that you will ever have to use the highest possible volume of the ringing tone. The same applies to the earpiece. Voice quality is good, the interlocutor is clearly audible, even in places where other devices are beginning to lose touch. In idle mode operate both SIM-card, but as a radio, can only receive calls on queue. Convenient to use the keyboard, move the buttons small and soft, with a distinct click when activated.

    The results

    Telephone Sigma mobile X-treme IP67 fully justifies the expectations placed on it. He is not afraid of any weather conditions and extreme situations. He catches a network where other devices are beginning to pass. It easily withstands week of active use, or two weeks in standby mode. In it the loud speakers. Of course, users accustomed to smartphones, the functionality of your phone may seem low, but hardly anyone would use Sigma mobile X-treme IP67, as the basic unit. Most likely it will be to get out of the box when to bring an expensive smartphone is dangerous, and read e-mail and news from social networks simply do not need and desire. Liked
