The Sendo S300 is a compact feature phone that was released in 2003, bringing basic mobile communication features to users at a time when mobile phones were transitioning from bulky devices to sleeker and more manageable gadgets. Although the S300 may now be considered ancient technology, at its time, it provided essential functionalities that catered to a market where simplicity and affordability were paramount.
Designed to operate on the GSM network, the Sendo S300 was compatible with GSM 900 and 1800 bands. Without GPRS and EDGE support, the device was purely for basic communication and did not incorporate internet capabilities, which at the time was a trade-off many users willingly made for a lower price point and longer battery life.
Announced in the first quarter of 2003, the Sendo S300 quickly captured the attention of those seeking a reliable mobile phone for calls and text messages. However, as technology rapidly evolved, the S300 was eventually discontinued, making way for newer models with advanced features.
The S300 was designed with dimensions of 107 x 47 x 21 mm and weighed approximately 90 grams, which fit comfortably in users’ hands and pockets. Its compact design was complemented by a simplistic and robust build, and since it used a Mini-SIM, it was easy to switch between devices. The S300 came in four colors: Midnight, Ink Blue, Frosty Mint, and Pepper Red, offering some degree of personalization to its users.
The device featured a monochrome graphic display with a resolution of 96 x 64 pixels that supported 5 lines of text with a 3:2 ratio. While it may not stand up to modern displays, it was perfectly capable of performing necessary tasks such as reading SMS messages and navigating the phone's menu.
The Sendo S300 provided a straightforward approach to memory and storage, offering phonebook storage for up to 200 contacts. Additionally, it could track up to 10 received, 10 dialed, and 10 missed calls, which was ample for typical daily use in the early 2000s. The absence of a memory card slot was not seen as a significant drawback for a device of this nature.
In keeping with its role as a basic mobile phone, the S300 did not include a loudspeaker or a 3.5mm jack, and it supported downloadable monophonic ringtones. Alert types were limited to vibration and these ringtones, serving as essential functionalities without overcomplication.
The Sendo S300 was very limited in connectivity options, as it did not support WLAN, Bluetooth, or radio. This minimalism helped keep the phone's power consumption low. While USB compatibility is mentioned, specific functionalities were not specified due to the era's limitations.
While limited in features by today's standards, the S300 came with four built-in games: Sumino, Carz, Splat, and Ten Pin. These simple games were a source of entertainment in a time before mobile gaming became sophisticated. Additionally, it supported multiple languages covering European, American, and Asian regions, catering to a wider audience.
The Sendo S300 housed a removable Li-Ion 600 mAh battery, renowned for providing a long standby time of up to 260 hours and a talk time of up to 5 hours. This performance was optimal for users who needed their phones to last days without requiring a recharge.
The Sendo S300 may seem nostalgically primitive today, but it served a vital role in the history of mobile telecommunications. It granted widespread access to mobile technology with a focus on simplicity, reliability, and affordability, easing the transition from stationary to mobile communications for many individuals.
