Demande carte vitale

Good afternoon, i'm sorry but i don't speak french, can someone help me in English or portuguese ?
I came to live here in March. My boyfriend has worked here for 5 years and then i moved here with our daughter.
I would like to know what i have to do to get my carte vitale and my social security number ?
I want to apply to the job center and look for work but i need to have both things first [ social security number and carte vitale].
So can you explaine to me what i have to do please ?
Thank you.
