Mobile phones, as we all know, play a significant role in our daily lives these days. However, they come with both advantages and disadvantages in my opinion.Firstly, mobile phones have made it convenient for people to stay in touch with each other no matter where they are. Especially when something important comes up, mobile phones help avoid the need for people to travel long distances to communicate in person. Secondly, we can send messages with minimal costs, just 0.01 yuan for each short message.Thirdly, we can also play games, take photos, or listen to music on our mobile phones.However, mobile phones also have many disadvantages. We have to pay for wrong numbers that are not intended for us. The radioactivities may do harm to our health. Sometimes, the rings may affect others in public places or at meetings. Therefore, we should be careful and make our phones powered-off in some occasions.In conclusion, mobile phones, as a tool to facilitate our lives, should be used appropriately to make convenience and reduce their negative impacts.
