The phone is used for playing games, making pictures, making videos, interacting with friends, and much more. From this we can conclude that a person cannot do without a mobile phone. I can’t imagine spending a day without a cell phone because I’m chatting with my friends, listening to music, watching movies, and even taking lessons. But besides, it could be an accident that very day, and it needs to come to call. So I think it’s impossible to do a day without a phone.
