The Comfort 50 Shell Duo Type-C is a classic flip phone, updated with modern solutions for convenience and safety. The model combines ease of use with useful multimedia and security features: USB Type-C for fast and convenient charging, a separate button for turning on the FM radio, blocking unknown numbers, and a more powerful 1000 mAh battery that provides up to a week of standby time.

Key advantages: an additional information screen to display time, battery charge, and caller ID during an incoming call; additional call and hang-up buttons to answer or reject a call without opening the case; a built-in antenna for listening to FM radio without a headset, and a separate radio button for instant access.

Connectivity: two slots for miniSIM cards (GSM network support), a microSD slot up to 32 GB for memory expansion.

The phone book can store up to 500 contacts in the device's memory; for each contact, you can save a name, number, photo, and individual ringtone. SMS memory allows storing up to 100 messages.

The "Organizer" section includes a calculator, calendar, alarm clock, and a bright flashlight with a separate button. The "Multimedia" section offers audio and video players, a camera with a 0.3 MP sensor, a voice recorder, and FM radio. Bluetooth allows connecting a stereo headset for comfortable music listening.

The 1000 mAh battery provides long operating time: calls, SMS, radio listening, and other basic functions with moderate use can last up to a week. The charge level is displayed on the additional information screen.

The SOS emergency call function is activated by pressing and holding the red button on the back of the device. SOS allows calling and sending SMS (if enabled) to 5 emergency numbers that you choose yourself. The SOS button works even when folded, and there is also a siren that can be turned on or off; to cancel the alarm, simply press the button again.

Additional useful features: speed dial for 8 numbers on keys 2–9; automatic call recording; voice announcement of actions during number dialing, incoming calls, and phone book search. Data protection is provided by setting a password for device activation and a PIN code for the SIM card. "Blacklist" and "Whitelist" functions allow blocking unwanted calls and granting access only to selected callers.
