It depends on how you're accessing videos. Youtube vidoes, thru m.youtube.com, are all free. Your data allowance is completely unlimited. There is no hidden 5GB cap like with the data cards. So any videos you watch thru the mobile web browser is all unlimited usage.
The Vpak also includes access to VCast Video, Verizon's video clip library, 95% of these videos are free. Only the music videos or premium videos will cost you. You'll see the charge when you're browsing thru the clips. If you highlight the name of the clip and let it scroll, all the way at the end it will have ($0.00) or ($2.49), and that's how you know what videos will charge you and which won't.
