Communicating with other people by telephone is very convenient,
especially when you have something urgent. For example, if one of your family members is seriously
ill at night, and you don’t know how to deal with it and where to find a doctor, what can you do? A telephone is the answer. Dial 120 and you will get services from the hospital very
soon.
