Samsung T639 Complete Specs Pricing Pros & Cons

Network and Connectivity

The Samsung T639 was released in 2007, a time when mobile phones were evolving rapidly. It supported dual-band GSM technologies, namely GSM 850, 900, 1800, and 1900. This made the device capable of providing decent 2G coverage across various regions. Additionally, the phone supported UMTS 1700, introducing early 3G speeds with data rates reaching up to 384 kbps. Though it might seem basic by today’s standards, back then, it provided users with fairly reliable internet access on the go, which was something of a luxury.

Design and Build

The Samsung T639 featured a classic flip-phone design that was quite popular in its day. The device measured 94 x 38 x 17 mm and weighed a mere 91 grams. Its compact dimensions and lightweight build made it an easy carry, ideal for users who preferred their devices to be both functional and unobtrusive. Furthermore, the phone used Mini-SIM standard, which was common before the transition to Micro and Nano SIMs.

Display and User Interface

The Samsung T639 came with a 2.2-inch TFT display capable of showing 256K colors. With a resolution of 176 x 220 pixels and a density of around 128 ppi, the screen was sufficiently vibrant for the time. The user interface was typical of feature phones of that era, providing users with functional menus and essential phone features such as contacts, message browsing, and basic multimedia functions.

Camera Specifications

On the photography front, the T639 was equipped with a 1.3 MP camera. This was standard for mobile phones at the time and allowed users to capture spontaneous moments with relative ease. Additionally, it supported video recording, providing an additional layer of functionality for users interested in capturing short video clips, though the quality was understandably modest given the limitations of the hardware.

Memory and Storage

The internal memory of the Samsung T639 was 30MB, allowing users to store a fair number of contacts, messages, and essential data. There was also a dedicated microSD slot that enabled users to expand the storage, which was a significant advantage for storing more media files and applications. The phonebook could store up to 1000 entries, and users could set photo calls, which was a valued feature for organizing and personalizing incoming calls. Furthermore, the phone could log 30 dialed, received, and missed calls.

Sound and Multimedia

Audio capabilities on the Samsung T639 included a loudspeaker for hands-free communication and the ability to use downloadable polyphonic and MP3 ringtones. However, it lacked the standard 3.5mm audio jack, which is a factor to consider for users who preferred using wired earphones. This would have led many to rely on a proprietary or Bluetooth-based alternative for audio output.

Communication and Connectivity Features

In terms of connectivity, the device offered Bluetooth 2.0 with A2DP support, which allowed users to connect to wireless headphones and other compatible devices. However, wifi and GPS support were absent, aligning with the technological limitations of the time. Low connectivity options earmarked it as a simple mobile device, primarily suited for calls, SMS, and limited internet usage via WAP 2.0/xHTML, HTML (NetFront 3.4) browsers.

Battery Life

The phone was powered by a removable Li-Ion 880 mAh battery, reflecting the norm for the build of handsets around that time. The battery had an impressive stand-by time of up to 250 hours and a talk time of up to 4 hours. This level of battery endurance meant users could go about their day without needing to charge multiple times, a significant advantage in maintaining uninterrupted communications.

Miscellaneous Features

Additional features of the Samsung T639 included basic games with the option to download more, SMS, MMS, and Email messaging capabilities. There was Java MIDP 2.0 support for running Java applications, which were quite popular before the app ecosystem expanded through Android and iOS. The phone was available in several colors such as Red, Green, Blue, and Cyan, offering a level of personalization. Moreover, it adhered to safety regulations with a SAR rating of 0.83 W/kg (head) and 0.38 W/kg (body).

Conclusion

The Samsung T639 embodied the design and technological capabilities of its time, offering a practical user experience with sufficient connectivity speeds for early 3G technology, a functional camera, simple audio solutions, and basic internet access. Although lacking the advanced features of modern smartphones, it served well within the realm of feature phones. Its affordability, reliable battery life, and classic design made it a notable mobile device for users who prioritized simplicity and essential mobile communication functions.
