Nokia 2100 is just a toy that is designed to fool the customers. Like the old model 3610 , 2100 also has the problem of range. It never catches the range when you need it. Very irritating for DOLPHIN users. Already dolphin has poor range and 2100 makes it worse.
The best range catcher is 8310 which is smaller but yet more powerful than 2100. Also 2100 has no voice dialing, this is very bad.
The battery is very loose fitting and if you just tap on the backside top of the piece it comes out of the position and most of the 2100 phones get switched off.
The processor used is very slow. If u have used the 3315 u will probably notice that the actions are very slow. You press the button and then after a second the action takes place.
Please avoid this peace. Nokia is fooling people by this piece.
