Hi!
  
  I'm thinking about getting an iPad Mini because it's the perfect size, weight, etc. I found one that comes with 4G Verizon, but it doesn't come with a SIM card. I don't know much about it and have a couple of questions:
  
  1. Even though the 4G Cellular comes with the iPad, do I still have to pay for the service?
  
  2. Is a SIM card necessary for the 4G to work?
  
  Thanks!
