When does a substance donot change its temperature even if it is heated?

During a phase change, a substance will remain at a constant temperature while it is being heated. In the case of melting ice, the heat initially goes into separating water molecules from the ice lattice, which is melting. During that time, the heat goes into continued melting of the ice and the temperature remains constant. Once all of the ice is melted, adding additional heat will increase the temperature of the now liquid water.
