This makes us more self-produced when making plans as you do not often get a busy signal and unlike a landline telephone, somebody is always home. Mobile phones also make us call if we are going to be late for work, although this has led to mobile phone users running late more often than those who do not have a mobile phone. These kinds of users seem to have adopted the behavior that appointment times are not concrete and use their mobile phones to arrange their arrival time.

The first thing you would no doubt do is to call home and have one of your family members read the list off to you. In the same condition in past years, you may have forgotten things or have had to drive all the way back home to get the things. If you have a problem on the road, you directly call for help instead of having to walk to find a landline. Mobile has certainly made our lives much easier.
