Samsung D820

This Samsung D820 mobile phone can be used with a GSM network service provider and it provides quad-band connectivity (850 MHz, 900 MHz, 1800 MHz, 1900 MHz). It does not come with a SIM card, and it requires that you provide a SIM card for usage with your selected service provider.

The D820's sliding design hides the phone's number pad under the display until you need to make a call. The massive, 240 x 320 display supports up to 262,000 colors - plenty of resolution and color depth for your videos and photos. A five-way center control button is positioned below the display, as are shortcut and selection keys. The phone's 1.3 megapixel camera is housed on the top of the cell phone and it swivels to face in or out. USB data and charging ports are located on the phone's bottom edge. There's also a connector for a stereo 2.5 mm headset on the left side, while the microSD slot resides on the right.

With 70 MB of internal memory, this Samsung D820 cell phone is designed to hold all the contacts, phone numbers and addresses you can throw at it. A call list remembers your most recent missed, received and dialed calls, and in addition to a vibrating alert, the D820 supports polyphonic ringtones and MP3-based music ringtones. A speakerphone lets you talk hands-free while you're doing other things, and picture caller ID lets you assign a photo to specific callers. Similarly, a ringer ID lets you assign ringtones to callers.

The Samsung D820 has all the bases covered when it comes to messaging. Support is built in for sending and receiving text, video, graphics and sound via messages. When used in combination with the phone's built-in camera, MMS opens up a whole new world of messaging fun. Messaging clients for AOL, Yahoo!, and ICQ are included.

Getting on the Internet is easy with the Samsung D820, too. It supports the GPRS protocol, as well as the new, high speed EDGE data protocol. When used with your carrier's data service and the phone's USB or Bluetooth data capability, the phone can be used as a wireless modem for laptops and PDAs. There's also a built-in browser for downloads and mobile Web browsing. T9 text entry, which is a technology that makes it easier for people to enter words and text on handsets, is built into the unit - a plus for mobile text messaging users.

A number of handy productivity tools are bundled with this Samsung D820 cell phone, including a voice memo recorder, an alarm clock, a calculator with currency converter, a calendar, and a to-do list.

The D820's built-in 1.3 megapixel camera captures stills and video to the phone's internal memory, or to an optional microSD memory card. The camera captures video at 352 x 288 resolution, and it features white balance and brightness controls. Meanwhile, the phone's powerful still camera sports a self-timer, a multi-shot mode, a night mode, brightness and white balance controls, ISO controls, and spot metering.
