it’s pretty simple, just put as the title, pros and cons of a phone, and then define what a cellphone is and then say what its used for, and then say what the problem is from your point of view and then list your first pro from the table u have, and then put your con and put a transition word (like then, or next) and then put what you think about the issue and lastly, just restate your issue in your conclusion.
hope this helps!
