I am a first-time cellphone user.  I have Wi-Fi provided by my broadband Internet provider (Comcast).  From what I understand, I should be able to piggyback off the Wi-Fi I already have to connect to the Internet via my new smartphone.  
Does this mean that I will not be charged for the data I use while connected to the Internet by the provider of my cellphone service? (My cellphone service is a cheap prepaid plan that runs on a GSM network).
Thank you.
