The Samsung SGH-E250 is very popular model, because of it’s design, like of Samsung SGH-D900 and Samsung SGH-D900i. It’s slider, pretty simple lies in a hand and all buttons placed very handful. This cell phone have a pretty good functionality for it’s price (about $200-$250) - very good TFT display (128×160 resolution, with 65k colors), VGA camera, microSD memory card slot, MP3-player and support of MP3 ringtones, FM-radio. But this mobile phone made in 2006, and needs to be renewed. The Samsung closely thought about it and… Welcome, a new cell phone!
The Samsung added 1 to number of model and released new Samsung SGH-E251. A little changes in design, front pannel buttons is the same, but function buttons now a little lower. Also, Samsung added “extra button” - in Samsung SGH-E250 pressing navigation key DOWN in stand-by mode means turn on the camera. Here, in the mobile phone Samsung SGH-E251 also navigation button UP have it’s own function - it turns on the musical player. Well, that’s all difference between this two cell phones. Now here’s all the functions of both of them: Display - TFT, 128×160 resolution, upto 65k colors.
Camera - VGA (0.3 Mpx)
Memory card - microSD slot (upto 1Gb in SGH-E250 and upto 2Gb in SGH-E251)
Additional - MMS, GPRS, EDGE, Bluetooth 2.0 (SGH-E251 supports A2DP - stereo BT headset), FM (SGH-E251 supports RDS), Java, MP3-support (such as player as ringtone).
