Overview of Sewon SG-2320CD

The Sewon SG-2320CD, introduced in the first quarter of 2004, is a feature phone that embodies simplicity and utility typical of early 2000s mobile technology. This device was released in an era when mobile phones were primarily used for communication, and thus, it offers the essential functionalities expected from a phone during its time. Although discontinued, it remains a topic of interest for those who enjoy exploring retro technology.

Design and Build

The SG-2320CD boasts a compact and lightweight design. With dimensions of 68 x 39 x 22 mm and a weight of just 72 grams, this phone was easy to carry and did not add much bulk to the user's pocket or bag. Its small size and lightweight nature were significant selling points at a time when consumers favored portability and convenience.

The body of the phone uses durable materials typical of devices from that era, ensuring the phone could withstand the rigors of daily use. The use of a Mini-SIM was akin to most devices of its time, offering standard connectivity options for users.

Display

Equipped with a CSTN screen capable of displaying 256 colors, the display of the SG-2320CD is modest by today's standards but was adequate for its main functions such as viewing text messages and navigating through the phone's menu. The screen resolution of 128 x 128 pixels ensured that text and simple graphics appeared clear enough for everyday usage. Although it lacks the vivid and crisp display qualities of modern smartphones, the focus of the SG-2320CD was on functionality rather than multimedia display.

Memory and Storage

The Sewon SG-2320CD comes with no additional card slot for memory expansion—a common trait among phones released at the time. It supports a phonebook capacity of up to 100 contacts, which was considered ample for average users. The device tracks call records for 10 dialed, 10 received, and 10 missed calls, providing basic but essential call tracking capabilities.

Sound and Alerts

Sound features on the SG-2320CD are minimalistic, with no loudspeaker or 3.5mm audio jack available. The phone relies on vibration and polyphonic ringtones with 16 tones available for alerts, aiming to fulfill basic alert needs. This absence of advanced sound features underlines the phone's focus on fundamental telephonic functions rather than media playback.

Connectivity

As a GSM phone supporting GSM 900 / 1800 bands, the SG-2320CD does not offer GPRS or EDGE, highlighting its limitation in terms of internet connectivity. The device was not built for modern data transmission, lacking features such as WLAN, Bluetooth, and GPS positioning. The absence of radio and USB connectivity further emphasizes its role as a communication tool rather than a multimedia device.

Battery Life

Powered by a removable Li-Ion 550 mAh battery, Sewon SG-2320CD provides a reasonable stand-by time of up to 100 hours and a talk time of approximately 3 hours. This battery performance indicates a focus on voice calls and messaging, with a capacity that supports typical usage without frequent recharges, catering well to the needs of its target audience during its release.

Messaging and Language Support

The phone's messaging capability is limited to SMS, which aligns with its positioning as a basic communication device. Supporting languages include English and Chinese, thereby catering to a broad audience where these languages are prevalent. The absence of advanced messaging or email features reaffirms its simplicity.

Additional Features

Staying true to its classification as a feature phone, the Sewon SG-2320CD does not support Java for running applications or sophisticated games, focusing instead on core phone capabilities. While advanced multimedia or computing functionalities are missing, this simplicity could be viewed as an advantage for users seeking distraction-free communication.

Conclusion

In summary, the Sewon SG-2320CD reflects the telecommunication needs and technological capabilities of its era. By offering basic mobile functionality and ease of use, it served its purpose well in the early 2000s. While it may not match the standards of today's smartphones, its simplicity, compactness, and reliability continue to make it a device of interest for collectors and enthusiasts of vintage mobile technology.
