Comfort 50 Optima Type-C — a convenient feature phone with a modern connector and updated functions

The Comfort 50 Optima TYPE-C red (3.5/2500/SOS) phone from Sigma Mobile is a practical and intuitive device in the Electronics > Phones category, designed specifically for people who need an easy-to-use button phone with up-to-date features. The model is available in two colors, including a vibrant red option.

The Comfort 50 Optima combines a large 3.5” color display with a resolution of 320x480 pixels, a convenient keypad with large, backlit keys, and voice prompts for actions. Thanks to the large screen, it's easier to type SMS, read e-books, and take notes — the font size can be increased for better readability. The keypad features characters for typing in Ukrainian, English, and Russian, making the device universally usable.

The modern USB Type-C connector ensures simple and fast connection to the charger: the cable can be inserted either way, which is especially useful for those with poor eyesight or in the dark. The Type-C port is also convenient for recharging other devices using a cable with two Type-C connectors.

Communications and memory: the device supports two miniSIM cards (GSM standards) and has a microSD card slot for up to 32 GB. The Comfort 50 Optima phonebook allows storing up to 1000 contacts in the device's memory; for each contact, you can add up to 2 numbers, a name, a photo, and a custom ringtone. Contacts can be grouped, imported, and exported. The phone also stores up to 1000 SMS messages.

Organizer functions: timer, stopwatch, alarm clock with the ability to set a custom melody, calculator, calendar with the option to mark tasks as completed or uncompleted, notes, and an e-book reader program — everything needed for daily planning and convenient record-keeping.

Multimedia and sound: The Comfort 50 Optima is equipped with audio and video players, a built-in FM radio with its own antenna (allowing you to listen to the radio without a headset), a voice recorder, and a 0.3 MP camera for simple photos. Bluetooth allows connecting a stereo headset for comfortable music listening.

The 2500 mAh battery provides exceptionally long operation — up to two weeks in normal use, so you can communicate, listen to music, and use notes for a long time without frequent recharges.

Safety and emergency functions: the phone has a special red SOS button on the back panel, which can be activated by pressing and holding. Once activated, the device sends an SMS message and then makes calls to up to 5 emergency numbers that you can specify. The SOS button works even when the screen is locked; if necessary, the siren and SMS sending can be disabled in the settings. To cancel the alarm, simply press the button again.

Additional useful features: speed dial for up to 8 numbers on keys 2–9 for instant communication with family or services, "Loudspeaker" mode for hands-free calls, automatic call recording to save important conversations, and voice prompts for actions — when dialing a number, during incoming calls, and when searching the phonebook, numbers and names are spoken aloud for user convenience.

Protection functions: ability to set a password for device activation and a PIN code for the SIM card; "Blacklist" and "Whitelist" help avoid unwanted calls by allowing calls only from selected subscribers or blocking unknown numbers.

The Comfort 50 Optima Type-C is an ideal choice for those looking for an easy-to-use, reliable, and functional button phone from Sigma Mobile with a modern Type-C port, a large screen, a long-lasting battery, and useful services for safety and daily comfort.
