Network Technology

The Sewon SGD-1010 is equipped with the GSM technology, which was the standard for mobile communications during the early 2000s. Operating on 2G bands specifically GSM 900 and 1800, the device lacks GPRS and EDGE, delivering basic telephony services without internet connectivity. This is typical of feature phones from that era, which were primarily focused on call and SMS functionality.

Launch and Availability

Announced in the first quarter of 2004, the Sewon SGD-1010 has since been discontinued. Back then, it offered a modestly innovative design compared to its predecessors. The phone had a brief lifecycle typical of feature phones during that period, where models were frequently updated and replaced by newer versions.

Design and Build

With dimensions of 82 x 44 x 21 mm and a weight of 90 grams, the device is compact and lightweight. It houses a Mini-SIM card slot, supporting the basic mobile telephone services of the time. The phone's build emphasizes portability and ease of handling, consistent with user preferences for simple and durable devices.

Display Features

The Sewon SGD-1010 sports an STN display capable of showing up to 65K colors at a resolution of 128 x 128 pixels with a 1:1 aspect ratio. The display technology and features reflect the typical usage scenario of the time, providing adequate visual performance for basic applications and text.

Memory and Storage

Storage on the SGD-1010 is quite limited, with no card slot for external memory expansion. Internally, it includes a phonebook capacity for 200 entries and call records storage support for up to 10 dialed, 10 received, and 10 missed calls, which suits routine usage patterns of its targeted consumer base.

Camera Specifications

The main camera is a single VGA sensor, which represents a basic level of photographic capability. Not designed for modern photography, it lacks video capabilities and front-facing camera, underscoring its primary function as a text and call-centric device.

Sound and Alerts

The device does not include a loudspeaker or a 3.5mm audio jack, but it supports a variety of alert types, including vibration and polyphonic ringtones (up to 64 tones). These features provide sufficient audio functionality for calls and message notifications.

Communication Options

There is no WLAN or Bluetooth capability, limiting its connectivity options to basic telephony functions. The absence of positioning systems, radio, and USB further reflects its limited scope in communications technology.

Additional Features

On the features side, the Sewon SGD-1010 supports SMS messaging and is available in English and Chinese languages. It does not support Java, lacking support for more advanced applications or games beyond the pre-installed features typical in basic phones.

Battery Life

Two battery options were mentioned, a removable Li-Ion 600 mAh and a standard Li-Ion 900 mAh battery. These power capacities were designed to provide substantial talk and standby times without the need for daily charging, appropriate for its limited energy demand.

Conclusion

The Sewon SGD-1010, like many feature phones of its time, provides fundamental mobile functionalities prioritizing call and SMS services over multimedia and connectivity features. While it lacks the advanced capabilities of modern smartphones, its compact design, straightforward user interface, and reliable battery life made it a suitable choice for users seeking simple mobile communication solutions during its active years.
