Imagine a situation that you are in a country where no one understands the language you speak
and you cannot read or write. However, you have mobile phone with you.
With a mobile phone with android, the Google translator translates the data of one language into
another language by using XMPP to transmit data. You can type the message in English and
select the language which is understood by the citizens of the country in order to reach the
message to the citizens.
