• Text messaging was launched to the cell phone market in the year 1993; at the time text messages were not very popular mostly because you could only type a few number of words.

Calendar and Planner• This cell phone feature has

proven to be very useful. Do you ever forget the date? If your cell phone has a date calendar all you have to do is open it up and it will tell you the date.

• Many cell phones also have planners which allow you to mark important dates on your calendar.

Color Screen
