A notable dual-SIM phone that incorporates both GSM and HSPA frequency technology is the Acer DX900, which was introduced in 2009. Its communication spectrum includes GSM 850/900/1800/1900 bands for SIM 1 and GSM 900/1800/1900 bands for SIM 2. While HSDPA 850/1900/2100 for SIM 1 provides HSPA speeds of 7.2/0.384 Mbps, its 3G brilliance shows. The phone, which is noticeably stylish, has dimensions of 106 x 60.5 x 17 mm, weighs 147 g, and supports a dual SIM setup.
Memory and Display
The smartphone displays a Samsung S3C 6410 CPU running at 533 MHz, with Microsoft Windows Mobile 6.1 Professional providing seamless orchestration. The dedicated microSD card port, which works in conjunction with the internal storage unit’s 128MB RAM and 256MB ROM, provides additional capacity as needed.
The display, which is encased in a TFT resistive touchscreen, features a rich 65K colour palette. The 2.8-inch visual canvas displays 480 × 640 pixels in quality. The display is as multifunctional as it is aesthetically pleasing, including both a widget-based user interface and handwriting recognition capabilities.
Camera
The 3.15 MP camera module has autofocus and an LED flash to provide clear pictures. The capability also includes video recording, with resolutions up to 720p. For video calls, a VGA front-facing camera is perfectly suited.
Sound and Features
The device ensures flawless communication and navigation thanks to its Wi-Fi 802.11 b/g, Bluetooth 2.0 with A2DP, and GPS capabilities, all powered by a SiRF Star III chipset. However, it just has a small USB connector and lacks radio capability. The usability of the Acer DX900 is increased with a variety of sensors, including an accelerometer. A fully supported HTML browsing experience is provided. Additionally, it has capabilities like an MP3 player and a voice memo tool. Even without a 3.5mm connection, audio output is routed through a built-in loudspeaker.
Battery
The Acer DX900 has an amazing talk time of up to 10 hours and a standby period of up to 150 hours thanks to its detachable Li-Po 1530 mAh battery. The device has a sophisticated appearance made of exquisite black. The Acer DX900, which sells for about 90 EUR, packs a tonne of features and abilities that elevate it beyond the competition in its era.
