Call forwarding from a mobile operator?

Question

mobile connection

Hello, tell me, is setting forwarding in the smartphone settings and forwarding in the settings of the personal account of the telecom operator is the same thing? It means that if I set forwarding in the smartphone settings, will the same settings be applied in my personal account and dial?
