NIU GO 21 Specs Pricing Pros & Cons Unveiled

Network and Connectivity

The NIU GO 21 is equipped with GSM technology, allowing the device to operate on 2G networks. It supports the GSM 850, 900, 1800, and 1900 bands for both SIM 1 and SIM 2, making it compatible with a wide range of global networks. While it does support GPRS with speeds up to 48 kbps, it lacks EDGE capability, which limits its data transfer efficiency when compared to more modern network technologies.

Launch and Availability

First announced in May 2014, the NIU GO 21 was released the following month in June. At the time of its release, it was positioned as a budget-friendly feature phone perfect for users who required basic functionality. However, it has since been discontinued, and users seeking a similar simple mobile experience must look towards other models or the second-hand market for this specific device.

Body and Design

The physical design of the NIU GO 21 caters to users who prefer a compact device. With dimensions of 105 x 44.9 x 14.2 mm and a lightweight build of just 66 grams, it’s easy to hold and carry in a pocket or bag. The device supports dual SIM (Mini-SIM), which is particularly useful for users who need to manage multiple phone numbers without carrying two mobile devices.

Display

The display of the NIU GO 21 is modest yet functional. It features a 1.8-inch TFT screen that displays 65K colors. The resolution of the screen is set at 128 x 160 pixels, with a pixel density of approximately 114 ppi. Despite its small size and basic quality, the display is sufficient for reading text messages and viewing simple graphics.

Memory and Storage

Internally, the NIU GO 21 comes with 32Mb of storage and an equivalent amount of RAM. While this is minimal by modern standards, it is adequate for its intended purpose of handling basic phone operations like storing contacts and maintaining call records. It is also equipped with a microSDHC card slot, allowing users to expand storage and store additional media files.

Camera

The NIU GO 21 features a single VGA main camera, which provides basic photographic capabilities. While it doesn't support advanced photography features, it can capture necessary moments and is suitable for users who prioritize simplicity over high-resolution imaging. However, the device does not include a selfie camera, which might be limiting for users wishing to engage in video communications or take front-facing photos.

Sound

Audio functionality on the NIU GO 21 includes a loudspeaker for hands-free use and a 3.5mm audio jack that allows the connection of headphones or external speakers. This ensures that users can enjoy music, radio, and calls with relative clarity, given the device's size and scope.

Communication Features

The phone supports Bluetooth 2.1 with EDR, allowing users to connect wirelessly to other devices, such as headsets or speakers. However, it does not include WLAN, NFC, or positioning technologies, reflecting its focus on basic communication needs. It features a stereo FM radio for entertainment and a microUSB 2.0 port for charging and data transfer.

Software and Features

The NIU GO 21 operates as a feature phone, providing basic messaging capabilities such as SMS, MMS, and instant messaging (IM). Although it includes some pre-installed games, it does not support Java-based applications, limiting the expansion of its software features. It remains a practical choice for users requiring fundamental communication tools without the complexities of smartphone operations.

Battery Life

One of the notable strengths of the NIU GO 21 is its battery life. The device is powered by a removable Li-Ion 650 mAh battery. On standby, it can last up to 200 hours, and during call time, it supports up to 6 hours of talk time. This is particularly beneficial for users requiring long-lasting battery performance in their daily routine.

Color Options

The NIU GO 21 provides a variety of color choices to suit different tastes, including black, orange, gray, red, green, and blue. This range of colors allows users to personalize their device according to their style preferences.
