Step-by-step explanation:
The answer is true. When possible, it is best to always travel with a cell phone. Cell phones provide a means of communication and can be crucial in emergency situations. For example, if you become separated from a friend or need to call for help, having a cell phone can greatly increase your chances of finding assistance.
