Hi,
I purchased a Nokia 3210 2 years back. One of the big disadvantages is that it is too heavy. The design of the cell phone is good, and nice to keep it in your hands. The operation of the equipement is smooth and does not take much time to learn.
If you want to have a cell which you can keep in your pocket, then this cell is a ’’NO’’. (Some guys use a pouch to keep their cell, and always hold it). However, some of the features are very good, like the ringtone composer.
I had dropped this cell phone quite a number of times, and it take the beating. Once I dropped it which driving my bike at ~50 kmph. It is rough and tough phone, which can take all the banging. However, it is very very sensitive to water / moisture. Once I was using it when I was sweating, and most probably the sweat seeped through the keypad and it damaged the circuit board! That was the last time I used it. I dumped it and bought another one.
Given, the many options now, I suggest you go for another phone.
