I’m test driving darkstar with warp as back up. Before I port everyone from T-Mobile I have account management question. Do I control all the lines as account owner (I do with T-Mobile)? Also, my wife and children are authorized to make changes on plan with T-Mobile and can log in to T-Mobile account through app or website through their credentials.

Is it possible to do this with USMOBILE? Reason being if one of them is traveling or needs to teleport to different network carrier (darkstar to warp), I don’t want to be asked to do it.
