text: There are times when we may need to use our cell phones though. For example if someone has to call their mom or dad to tell them that they have an after school activity. How else would they be able to communicate with them. Another example would be if two students had to do a project together and had to start during lunch or study hall. If they did not have any classes together before then they could easily text each other in between class periods and find out a time that they could both work on the project.
