There are many different types of telephone. A telephone that can be carried around is called a [[mobileхөдөлгөөнт phoneхолбоо]] orбуюу cellүүрэн phoneхолбоо. These became popular in the late [[1980]]s. These days most people carry mobile phones and in some cities or countries it is unusual to not have one. Some mobile phones are able to make telephone calls using [[satellite]]s instead of masts on the ground, which means people can make calls from anywhere in the world.
 
[[ComputerКомпьютер]]s can use a machine called a [[modemмодем]] to talk to other computers over a telephone line. This allows a computer to connect to other [[computer network]]s including the [[InternetИнтернэт]].
 
Ихэнхи улс орнуудад нийтийн телефон мөн хэрэглэгддэг. To use one people have to pay with [[coins]], a [[credit card]] or a [[prepaid card]].
 
Most countries have a telephone [[networkсүлжээ]]. In less developed countries cell phones are used as a cheaper and faster way to bring modern communications to the countryside.
 
Each telephone has a unique number. Today, telephone numbers are about seven to ten digits long. Part of the telephone number is called the ''area code''. Area codes are used to make sure the numbers are not the same in two different places. Each area has their own area code.
