What is the family communication of parents' smart phones?

Boss, this family communication is the most critical function. I feel that this is the core value of Zhongnuo W1. In the family communication, you can bind your son's daughter's or grandson's mobile phone number, for example, if the old man binds his son's mobile phone number, the son can use his parents' smart phone cloud platform to remotely help the old man send photos, music, modify and add a phone book, etc. Moreover, when the old man is in trouble, he can call his son directly or automatically send a geographical message to him.
