Memory size:+ memory card slot
Camera:0.3 MP
Battery:2500 mAh, removable
The push-button telephone from the Comfort series of the Ukrainian brand Sigma is designed primarily for older users who value simplicity and ease of use. Although the device itself is small, it is equipped with a fairly large screen with a diagonal of 3.5", on which text and images are clearly visible. Because of this, the buttons here are more compact, which more than pays off with large symbols.
The phone book allows you to save up to 1000 numbers, and for each contact you can record two numbers, set a photo and your own melody. Supports two SIM-cards, there is also a separate slot for a microSD memory card up to 32 GB. In addition, for the elderly, Sigma Comfort 50 Optima offers voice for some actions (incoming calls, dialing, number in the phone book), a flashlight, an alarm clock, a calculator, a calendar with the ability to create events, a 0.3 MP camera, FM radio with a built-in antenna . But the most important thing is the presence of the SOS button for emergency situations. When pressed, the phone will send messages and make calls to emergency contacts — up to 5 numbers can be stored. The SOS button works even with the screen locked. Finally, a 2500 mAh battery, according to the manufacturer, will provide up to two weeks of battery life.

Model overview based on user reviews
The Sigma mobile Comfort 50 Optima is a button phone designed with simplicity and functionality in mind, making it ideal for users who prefer straightforward mobile devices. One of its standout features is the large screen, which enhances readability and usability, complemented by a large font option for those with visual impairments. The phone also boasts a capacious battery, ensuring extended usage time without frequent recharging. It supports storing up to 1000 contacts and 1000 SMS, with the ability to import and export data to a memory card, providing ample storage for essential information. Additional features include a timer, stopwatch, and the ability to read books, which are rare in similar devices. However, some users have reported issues with sticky buttons and screen malfunctions, which could affect the device's reliability. The joystick control may initially be inconvenient, but users can adapt over time. Despite these drawbacks, the phone's spam filtering capabilities and overall functionality make it a practical choice for those seeking a basic yet efficient mobile phone.

Do not buy! Bought it for my mom at Foxtrot before the war, went to the store on the second day with the phone because the buttons were sticking, they sent it to Kyiv for a month since there are no service centers for this model in Mykolaiv. When they brought it back, the battery stopped working over time. Wasted money and ruined nerves. I no longer go to Foxtrot in Mykolaiv. No advantages. Everything was disappointing  Lyudmila Spivak: use Sigma mobile Comfort 50 Optima less than month |
Horror model. Bought in Citrus. Worked for 2.5 weeks and the screen went out. And in the service center they said that the display is not available and will not be. I advise you not to buy, money down the drain. I liked the fact that the screen is large and the battery. This screen is missing. Andrey Sulima: use Sigma mobile Comfort 50 Optima less than month |
