The Haier K3 is a feature phone that was launched in 2010. Despite being a simple device by today's standards, it served its purpose well during its time. The phone targets users who require basic functionalities such as calling and messaging without the complexities of a smartphone.
The device supports GSM technology and operates on 2G bands GSM 900 / 1800. It features a GPRS class 10 but lacks EDGE support, making it limited to basic internet connectivity. This makes the Haier K3 suitable for users who predominantly need it for voice communication and SMS rather than internet usage.
The Haier K3 features dimensions of 109 x 51 x 17.4 mm, which makes it quite compact and easy to hold. Despite the lack of official information about its weight, the body feels robust due to its durable construction. The design includes support for Dual SIM (Mini-SIM), which is a convenient feature for users who need to manage two phone numbers.
The device sports a 2.6-inch TFT display capable of showing 65K colors. The resolution stands at 240 x 400 pixels, yielding relatively low pixel density of approximately 179 ppi. Though this cannot compete with modern smartphones, the display was adequate for basic functionalities such as reading text messages and viewing contact lists.
Equipped with a single VGA camera, the Haier K3’s camera offers a resolution of 0.3 MP. While the camera lacks video recording capabilities, it suffices for capturing simple photos. This basic setup reflects the phone's focus on essential communication needs rather than multimedia consumption.
In terms of memory, the Haier K3 includes a microSD card slot for expanding storage, allowing users to store their media and contacts externally. The phonebook feature is supported, providing an essential tool for managing contact information effectively.
The Haier K3 comes with a loudspeaker that ensures clear audio output for calls and FM radio listening. It lacks a 3.5mm audio jack, which might limit the use of headphones directly. Bluetooth 2.0 is available for basic data transfer between devices, although it lacks modern speed and support for advanced wireless features.
Haier K3 features SMS and MMS messaging capabilities. With a WAP 2.0/xHTML browser, it provides limited access to basic internet-branded content. Java support (MIDP 2.0) allows users to load Java-based applications, although availability and compatibility are quite limited.
The device is powered by a removable Li-Ion 1000 mAh battery, which provides adequate life for a feature phone. This capacity allows for extended talk time and standby, given the energy efficiency of simpler hardware compared to modern smartphones.
Overall, the Haier K3 serves as a practical and reliable feature phone, especially suitable for users who require basic functionalities and appreciate simplicity. Its support for dual SIM, combined with a robust design, makes it a viable option for users in regions with varying network availability.
