Price and specifications of Sewon SGD-102 advantages, disadvantages, and a comprehensive explanation

Introduction to Sewon SGD-102

The Sewon SGD-102 is a feature phone that was introduced in the first quarter of 2004. It represents a period in mobile technology where functionality was prioritized over the advanced capabilities we see in modern smartphones. Despite its limited features compared to today's standards, the Sewon SGD-102 served its purpose effectively by providing essential telecommunication services to its users.

Network Capabilities

The Sewon SGD-102 operates on GSM technology. It supports 2G bands, specifically GSM 900 and 1800. However, it does not support GPRS or EDGE, which limits its mobile data communication capabilities. This device was strictly for making and receiving calls and sending SMS.

Design and Build

The device boasts compact dimensions of 72 x 40 x 23 mm, making it extremely portable and easy to handle. It weighs just 80 grams, which adds to its portability. The phone is designed to use a Mini-SIM, which was commonly used during its time of release.

Display Features

The Sewon SGD-102 is equipped with a CSTN display that can show up to 256 colors. Its resolution is 128 x 128 pixels with a 1:1 aspect ratio. Although it may seem basic by today's standards, this was typical of feature phones at the time.

Memory and Storage

The phone does not support external memory cards, which means users can only rely on its internal storage. The phonebook can store up to 100 contacts. Additionally, it can keep records of the last 10 dialed, received, and missed calls, which was a useful feature for its users.

Sound and Alerts

Unlike modern phones, the Sewon SGD-102 does not have a loudspeaker. It offers polyphonic ringtones with 16 channels and supports vibration alerts. However, it lacks a 3.5mm headphone jack, limiting external audio output options.

Communication Features

The phone lacks several modern communication features that are often taken for granted today. It does not support any form of wireless communication, such as WLAN or Bluetooth. Furthermore, there is no built-in GPS or radio feature.

Battery Performance

The Sewon SGD-102 comes with a removable Lithium-Ion battery with a capacity of 550 mAh. Its battery life is sufficient for basic functions, providing up to 110 hours of standby time and up to 3 hours of talk time, which was quite reasonable for phones during that period.

Software and Features

The device operates as a feature phone with a focus on basic telephony. It supports SMS messaging and offers a limited number of pre-installed languages, notably English and Chinese. There are no advanced browsing capabilities or Java support, which characterizes this device as very basic in terms of software features.

Summary and Legacy

Despite its limited capabilities, the Sewon SGD-102 represents an era of mobile phones where the focus was primarily on call quality and battery life rather than entertainment or internet connectivity. It serves as a remarkable example of the early 2000s mobile technology landscape, embodying simplicity and functionality.

This phone is a nostalgic reminder for many who used it during its time, offering insight into how far mobile technology has progressed since then. While it may not meet the demands of today's tech-savvy users, its role in mobile phone evolution remains significant.
