Hey Guys,
Just noticed this on a google ad:

That 100mb data plan would be far better for my data card than our current 200MB on account plan. Does this charge like $10 text where you pay at the start of a month and you just get 100MB for the entire month?

Also do you need a new sim card to use it (and hence the inc. sim $39.95 part)?
