The Nokia 230 Dual SIM operates on the GSM technology, which has been a widely adopted standard for mobile communication across the globe. This device supports the GSM 900 / 1800 frequency bands, ensuring compatibility with many mobile networks, particularly in Europe, Africa, and parts of Asia. Its GPRS capability allows data transfer at speeds of up to 85.6 kbps, while EDGE technology offers improved data speeds of up to 236.8 kbps, enhancing the user experience for basic internet browsing and downloading small files.
The device was announced in November 2015 and subsequently released in December 2015. However, it has since been discontinued, marking its availability as limited to the existing stocks in the market. Despite its discontinuation, the Nokia 230 Dual SIM remains a reliable option for those seeking basic mobile phone functionality.
The Nokia 230 Dual SIM is characterized by its classic bar phone design. With dimensions measuring 124.6 x 53.4 x 10.9 mm, it offers a compact and lightweight experience at just 91.8 grams, making it easy to carry and operate with one hand. The device supports Dual SIM functionality using Mini-SIM slots, which provides the convenience of using two separate mobile numbers on a single device, beneficial for managing personal and professional contacts.
Equipped with a 2.8-inch TFT display, the Nokia 230 Dual SIM provides a screen area sufficient for reading texts and viewing images without excessive scrolling. The screen displays 65K colors at a resolution of 240 x 320 pixels. Although not high-definition by modern standards, the 143 ppi pixel density ensures that the display quality is clear enough for its intended basic phone functions.
The device comes with 16MB of RAM, a modest yet functional capacity for its feature phone category. It includes a dedicated microSDHC card slot to expand storage, thereby accommodating additional content such as songs, photos, and contacts. The phonebook can store up to 1000 entries, making it a handy option for users with extensive contacts lists. Call records are also supported, allowing users to keep track of their call history effectively.
The Nokia 230 Dual SIM features a single 2 MP rear camera, accompanied by an LED flash for low-light photography. The camera is capable of recording video at 240p resolution and 15 frames per second, suitable for capturing simple moments without the complexities of advanced mobile photography. Though basic, the camera in this device serves the function of capturing essential photos and videos for users who require minimal camera usage.
Additionally, the front-facing camera also sports a 2 MP sensor with an LED flash, a rare feature among feature phones at its time of release. This allows for convenient selfies and video calls, albeit at 480p video resolution, which is acceptable for basic video communication.
The device includes a loudspeaker and a 3.5mm audio jack, providing options for hands-free use and personal listening with compatible earphones or headphones. This feature enhances the usability of media playback and FM radio functionalities.
While the Nokia 230 Dual SIM does not support WLAN or positioning services like GPS, it compensates with Bluetooth 3.0 and A2DP for wireless data transfer and compatibility with a range of Bluetooth-enabled devices. The inclusion of a stereo FM radio allows users to enjoy music and informational broadcasts, while the microUSB 1.1 port ensures connectivity for data transfers and charging.
The Nokia 230 Dual SIM does not include advanced sensors typical in smartphones but provides functionality for messaging through SMS in threaded view, MMS, and instant messaging (IM). Preloaded games add to the entertainment aspect, though it does not support Java applications, slightly limiting the scope of additional downloadable apps or games.
Fitted with a removable Li-Ion 1200 mAh battery, the device impresses with extensive battery longevity. The standby time extends up to 528 hours, while talk time can reach up to 23 hours, and music play up to 52 hours. This long battery life is one of its standout features, addressing the needs of users who require a reliable device that doesn't require frequent charging.
Available in classic black and white colors, the Nokia 230 Dual SIM maintains a sleek and minimalist appearance. The SAR values indicate that the device is safe for everyday use with manageable radiation emission levels. Upon release, it was priced at about 70 EUR, offering a cost-effective solution for those in need of a basic mobile phone with essential features.
