My actual mobile phone is a Samsung Galaxy 4, it was a present of my father because the mobile phone I used to use was very basic phone. So, this mobile phone has a lot of different uses apart from talking, like listening music, chat with my family and friends by WhatsApp, and many other applications.
I use it all days of the week, because it is the main way wich I can comunicate with friends and family. And everyday when I travel by transantiago i am listening music too.
All these reasons are important, and thats why i like it.
Finally, if I dont have my mobil phone, i wont desesperate, but things would be different.
