When do you use mobile phones?

The purposes that I use my mobile phone is, I use it to SMS text friends, to have conversations with friends and family, use it for its media e.g. MP3 player, camera, camcorder.
I use my mobile phone anywhere, I use it at home, when I am out ect. I use when ever I need to contact someone for some information or when I am contacted.
The major benefits of me using my mobile phone is that, my mobile phone can be used almost anywhere, my mobile phone can contact any number at anytime I want it to, my mobile phone does’ not just contact people but also can be used for entertainment, its extra applications such as alarm clock, calendar ect.
The major disadvantages of using a mobile phone is that it can only be used to contact people if it has good signal strength. Also the mobile phone battery is not a very long lasting battery and needs to be recharged every few days.
My mobile phone fulfils its intended purposes of being able to contact people I want it to, being able to use its alarm clocks, calendars ect.
