To express the idea that a mobile phone should not be relied upon as the sole means of protection for a child, and that we should instead prioritize more direct supervision and care, you could phrase your statement as follows:

"A mobile phone should not be seen as a substitute for parental supervision and care, but rather an added tool for communication and safety. It is important to remember that our children need our direct attention and guidance to ensure their well-being."

This statement emphasizes the importance of active parenting involvement, beyond simply relying on a mobile phone for protection. Additionally, it acknowledges that while mobile phones can be useful tools, they are not sufficient on their own for ensuring a child's safety and well-being.
