IPhone 4s sim card (3G) in galaxy s4 (4g phone)?

I recently saw that amazon had a good deal on the galaxy s4, it was $0.01 on a two year contract. I decided to purchase this and have it shipped to my house. Can I put my 3G sim card in this 4g phone? And if I do will I have 4g service or 3G service? If I go to Verizon and get a 4g sim what will that cost me? Will I then have to pay an activation fee? Any help would be great, thanks.

Added (1). I'm on Verizon by the way.

Yeah the sim will work had the exact same issue my myself but tge sim will work on 3g as it is a 3g sim I habe no idea about the cost cause I don't live in that region glad to help.
