The Celkon C747, announced in 2010, is a feature phone designed to meet the basic needs of communication and entertainment in an affordable package. While no longer in production, this device catered to users seeking simplicity and functionality over advanced smartphone capabilities.
The Celkon C747 features a compact design with dimensions of 112 x 47 x 13 mm, making it comfortable to hold and easy to fit into pockets. Weighing just 128 grams, it is lightweight but sturdy. The device supports Dual SIM (Mini-SIM), allowing users to manage two phone numbers simultaneously—a handy feature for separating work and personal communications or for users in regions with varied network coverages.
Equipped with a 2.2-inch TFT display, the Celkon C747 provides a resolution of 176 x 220 pixels. While this screen size and pixel density (~128 ppi) are modest by modern standards, they are adequate for a feature phone, focusing on basic tasks such as texting, calling, and viewing photos.
The phone includes a simple 2 MP main camera capable of shooting photos and recording video. This basic camera functionality is suitable for casual captures, documenting everyday moments without the need for advanced photography features.
One of the competitive aspects of the Celkon C747 is its battery. Powered by a removable Li-Ion 1500 mAh battery, the phone offers up to 550 hours on standby and approximately 6 hours and 40 minutes of talk time. The ability to replace the battery extends the device's lifespan, as users can swap out old batteries for new ones when needed.
Supporting GSM technology with bands for GSM 850 / 900 / 1800 / 1900, the Celkon C747 ensures compatibility with a wide range of networks. While it provides GPRS connectivity, it lacks capabilities such as EDGE or 3G data, limiting its use for internet applications. Bluetooth 2.0 is available for wireless file transfers, and a microUSB port is included for charging and data transfer. Additionally, WFM radio support adds media variety.
The phone comes with a microSDHC card slot, providing the option to expand memory for storage of media files, contacts, and call logs. It can store up to 1000 phonebook entries, along with records of 20 dialed, 20 received, and 20 missed calls, making it suitable for users with moderate storage needs.
Although basic, the Celkon C747 includes features such as SMS and MMS messaging, allowing users to send and receive text and multimedia messages. The phone comes preloaded with simple games, offering entertainment without the complexity of modern mobile games. However, it does not support Java-based applications, limiting the software expandability.
The device includes a loudspeaker for hands-free calls and audio playback. For sound quality during calls, it maintains the standard of feature phones from its era. Moreover, the phone is equipped with an accelerometer sensor, though application possibilities for this sensor in the context of a feature phone are limited.
Originally priced at around 50 EUR, the Celkon C747 offered a budget-friendly option for consumers seeking basic functionality without investing in a smartphone. The device's straightforward features and affordable price made it a popular choice in emerging markets and among users who preferred simplicity.
In summary, the Celkon C747 stands as a practical example of a feature phone catering to basic communication needs with added conveniences such as Dual SIM support and expandable storage. While it may not cater to users seeking the latest in mobile technology, its straightforward design, reliable battery life, and affordable pricing kept it relevant to its target audience. Although discontinued, the Celkon C747 remains a noteworthy representation of affordable mobile communication from its time.
