The Sendo S600 was introduced in the first quarter of 2004 and quickly became known for its functional simplicity and reliability. As a feature phone, it catered to a segment of users looking for basic mobile functionalities without the complexities of modern smartphones. While it has been discontinued, the S600 remains a noteworthy example of early mobile technology.
The Sendo S600 utilized the GSM technology, a prominent choice for mobile connectivity during its time. It supported GSM 900/1800 frequency bands, making it versatile across various regions. Although it lacked advanced data capabilities like EDGE, the inclusion of GPRS Class 8 allowed users basic internet connectivity. This was sufficient for lighter tasks such as browsing and messaging.
With dimensions of 108 x 45 x 20 mm and a weight of 83 grams, the Sendo S600 offered a compact and lightweight design. The device was designed to fit comfortably in the hand, featuring a Mini-SIM slot for telecommunications. Although the materials used were basic to keep costs low, the tactile buttons and durable casing ensured long-term usability.
The phone sported a TFT display capable of showing 65K colors. Even with a modest resolution of 128 x 128 pixels, the screen was adequately suited for basic tasks such as reading messages and viewing contact photos. Despite not being geared for multimedia consumption, its straightforward interface made navigation easy.
The internal memory of the Sendo S600 was limited to 3.7MB, with no provision for expandable storage through a card slot. It managed a phonebook capacity of up to 750 contacts (250 x 3 entries) with photo call capabilities. The device recorded up to 10 dialed, received, and missed calls, reflecting its design for basic communications rather than extensive data storage.
Equipped with a VGA camera, the Sendo S600 allowed users to capture simple photos, adhering to the trend when mobile photography was a novelty. Although video recording capabilities were absent, the camera sufficed for basic photography needs, offering a glimpse into the early days of mobile imaging.
Alert types included vibration and polyphonic ringtones, the latter of which users could download. However, it lacked a loudspeaker and a 3.5mm audio jack, reflecting its focus on voice calls over media playback. Despite these limitations, the customizable alerts catered to personalization preferences among users.
In terms of connectivity, the Sendo S600 had no support for advanced features such as Bluetooth or WLAN. It also lacked positioning services and a radio. The absence of these features is indicative of the era when mobile phones largely prioritized basic telephony and text messaging services.
The Sendo S600 supported various messaging formats, including SMS, EMS, and MMS. With a basic WAP 2.0/xHTML browser, users could access lightweight versions of the web. It came preloaded with three games and offered Java support (MIDP 2.0), enabling users to download additional applications and games that enhanced its utility.
Powered by a removable Li-Ion battery, the S600 offered a standby time of up to 450 hours and a talk time of approximately 7 hours. This endurance was commendable, particularly for users who required a reliable device that could last throughout the day without frequent recharging.
In summary, the Sendo S600 represented an era of mobile innovation driven by practicality and user-centric design. Although it lacked the sophisticated features of modern smartphones, its robust build, reliable performance, and user-friendly interface made it a valuable device for consumers during its prime. Today, it serves as a reminder of the rapid technological advancements in the mobile industry and the humble beginnings of mobile connectivity.
