Mom wants to confiscate her mobile phone. How can I tell her not to confiscate it?

If you are in junior high school or high school, I suggest you give your mobile phone to your mother, because you are in a very important learning period. If you play with your mobile phone every day, it will delay your study. Your mother gave it to you for your own good. Well, playing with mobile phones is easy to cause myopia now, and the monthly telephone bill is also very huge, which is equivalent to a very huge consumption now, so don't think about how to escape the management of your parents. But thinking about how to put your future. Vow to be better. Say study hard next time and let your parents see your grades. Your grades must be improved next time. If you really can't, write a guarantee. There are many ways anyway. Please tell me the details and I'll give you the answer! If you are satisfied, please accept it.
