Introduction to Siemens AL21

The Siemens AL21 was released in November 2005, positioned as a feature phone during an era when mobile devices were primarily focused on performing basic communication tasks rather than multi-functional smartphone capabilities. This device catered to users seeking an affordable and functional phone for regular use without the complexities of modern smartphones.

Design and Build

The Siemens AL21 sports a compact design with dimensions of 86.8 x 45.8 x 19.2 mm, making it easy to handle and carry. Weighing just 78 grams, it fits comfortably in pockets and bags. The device is constructed using durable materials and comes in two color options: Red Temptation and Black Magic. Its simplicity and practicality were standout features at the time of its release.

Display Specifications

The phone features a TFT display with 65K colors, offering basic visual performance suitable for tasks like messaging and browsing. Although the display doesn't match up to modern standards, it provided a resolution of 130 x 130 pixels, delivering decent clarity for a feature phone.

Network and Connectivity

The Siemens AL21 operates on GSM networks, supporting frequency bands GSM 900 / 1800 / 1900, which allowed for decent call reception and connectivity during its time. It also featured GPRS Class 8 for basic internet connectivity but lacked EDGE and most contemporary connectivity features like Bluetooth, WLAN, and GPS.

Storage and Memory

Equipped with an internal storage of 1.5MB, the AL21 could store a limited amount of data, including contacts and messages. There was no provision for expandable storage via a memory card slot. Its memory capabilities supported basic phonebook functionalities and call records of 10 dialed, received, and missed calls each.

Battery Life

The AL21 comes with a removable Li-Ion 600 mAh battery, providing adequate power to keep the device functioning throughout the day. It offers up to 220 hours of standby time and up to 5 hours of talk time, making it reliable for regular daily use.

Communication and Messaging

The Siemens AL21 was built to handle essential communication needs, with support for SMS, EMS, and MMS for sending and receiving various types of messages. The device also included a WAP 1.2.1 browser for accessing basic internet services, which was a notable feature during its time.

Additional Features

The phone included additional features like polyphonic ringtones, vibration alerts, and downloadable games, alongside support for Java MIDP 1.0 applications, allowing for basic app installations. Though limited, these features added a layer of personalization and entertainment for users.

Sound and Audio

The Siemens AL21 included a loudspeaker for hands-free operation and polyphonic (32) ringtones to provide a range of sound alerts for calls and notifications. However, it lacked a 3.5mm audio jack, which limited audio output options to the device’s own speakers or proprietary earphones.

Conclusion

Siemens AL21 embodies the quintessential feature phone of the mid-2000s, offering essential communication tools without the complexities of modern smartphones. Its compact design, basic connectivity, and reliable performance made it a suitable choice for users desiring straightforward, everyday functionality. Despite its discontinuation, the AL21 remains a symbol of an era focused on simplicity and reliability in mobile communication.
