Mobile phone

  Mobile phone A   mobile phone   (also known as a   hand phone ,   cell phone , or   cellular telephone [1] ) is a small portable   radio   telephone . Siemens  AX72. The mobile phone can be used to communicate over long distances without wires. It works by communicating with a nearby base station (also called a "mobile tower") which connects it to the main phone network. When moving, if the mobile phone gets too far away from the cell it is connected to, that cell sends a message to another cell to tell the new cell to take over the call. This is called a "hand off," and the call continues with the new cell the phone is connected to. The hand-off is done so well and carefully that the user will usually never even know that the call was transferred to another cell. As mobile phones became more popular, they began to cost less money, and more people could afford them. Monthly plans became available for rates as low as US$30 or US$40 a month. ...

A proud statue of Saradial can still be seen at Galigamuwa Junction.  Climbing is not difficult, as you can see the mountains clearly.  But it is wise to climb without making too much noise because there are wasps.   The other important thing is that the road near the top of the hill is very dangerous.
