Nokia 6650 fold

The feature list says that this phone can be used as a modem for a laptop. Am I correct to assume that this means that it is using voice minutes while connected? In other words, if I used it as a modem in off-hours (after 9pm), then it would provide my laptop with free connectivity to the internet (using an ISP's or corporate dial-in access number) without need for the data plan?

Thanks!
