The Alcatel OT-S621 is a mobile device that represents an era of feature phones that prioritized simplicity and essential functionalities. Released in 2008, the Alcatel OT-S621 targets users seeking a basic mobile communication experience without the complexities of modern smartphones. Despite being discontinued, the phone remains a point of reference for those interested in the evolution of mobile technology.
The Alcatel OT-S621 operates on GSM technology, specifically supporting GSM 900 and 1800 bands, making it suitable for 2G networks. It supports GPRS Class 10 for basic internet connectivity, but does not include EDGE, meaning its data transfer capabilities are limited compared to later generations of mobile technology. The absence of modern connectivity options like WLAN and NFC reflects its era, although it includes Bluetooth 2.0 with A2DP for sharing files and connecting to wireless headsets. Notably, it lacks GPS positioning and radio functionality.
Measuring 103.5 x 44.9 x 10.9 mm and weighing a mere 69 grams, the Alcatel OT-S621 is lightweight and compact, fitting easily into pockets and hands. The device uses a Mini-SIM, a standard at the time of its release. The phone’s exterior is designed with a dark chrome finish, giving it a sleek look for its time. Despite its small stature, the phone’s ergonomic design allows for comfortable operation during voice calls or text messaging.
The phone features a 1.8-inch STN display capable of showing 65K colors, with a resolution of 128 x 160 pixels. This results in a pixel density of approximately 114 ppi. While this seems modest by today’s standards, it was adequate for viewing menus, messages, and basic images. The screen occupies about 21.9% of the phone's body, emphasizing its focus on keypad functionality.
Equipped with a single 1.3 MP rear camera, the Alcatel OT-S621 allows users to capture basic photos and videos. Given the time of its release, the camera was not expected to deliver high-quality images but served as a practical tool for casual photography needs. The absence of a front-facing camera means that features like selfies and video calls were not supported.
The device comes with 10 MB of internal storage, which is extremely limited by today’s standards but was typical for feature phones of that era. This storage is mainly used for contacts and SMS storage, with room for very few multimedia files. Fortunately, the phone includes a dedicated microSD slot for expanded storage, allowing users to add more space for photos, music, and other data. The phonebook can store up to 800 entries, addressing the basic needs for contact storage. Call records include logs for 20 dialed, 20 received, and 20 missed calls, making it easy to keep track of recent communications.
The Alcatel OT-S621 operates on a proprietary feature phone system, which is designed for straightforward use, focusing on essential communication features rather than smartphone-style applications. Due to its limited processing capability, the phone supports basic Java-based applications and games, specifically Java MIDP 2.0. The phone’s performance is tuned to handle SMS, MMS, Email functionalities, and a WAP 2.0/xHTML browser for simple internet access.
Sound is a crucial aspect of mobile communication, and the OT-S621 includes a loudspeaker for hands-free use and supports vibration alerts alongside polyphonic and MP3 ringtones. However, it lacks a 3.5mm audio jack, which limits the use of standard headphones unless an adapter or compatible accessory is used.
The Alcatel OT-S621 is fitted with a removable Li-Ion 750 mAh battery, which provides a standby time of up to 400 hours and talk time up to 10 hours. This longevity is feasible due to the phone’s low-power requirements, a characteristic feature of non-smartphones. Users could expect to use the device for several days on a single charge, which is a significant advantage over today’s smartphones.
The device was available in a single color option, Dark Chrome, delivering a minimalistic aesthetic suitable for general use. Users could engage in text messaging with SMS, MMS, and Email support, while its browser enabled the exploration of internet content in a limited capacity. The phone also includes basic games, a common feature in feature phones designed to provide simple entertainment options. With a SAR EU rating of 1.00 W/kg (head), it falls within the safety standards applicable to mobile devices regarding radiofrequency emissions.
In conclusion, the Alcatel OT-S621 is a testament to a more straightforward era of mobile phones. It emphasizes connectivity and essential features without the myriad of functions found in modern devices. While it may appear antiquated by today’s standards, it offers valuable insights into the evolution of mobile technology and serves utility in contexts where advanced functionalities are unnecessary. For those interested in a no-nonsense mobile experience or exploring the development of mobile tech, the Alcatel OT-S621 stands as an informative reference point.
