It says it's free but under the t's and c's it states:
6. Fees
Your use of the Service may be or may become subject to charges.
Any fees charged by Nokia will be announced separately in connection with the Service.
Use of the Service may involve transmission of data through your service provider's network. Your network service provider may charge for such data transmission.
Nokia assumes no responsibility for the payment of any charges
I'd assume that just means the mobile network may charge, but the site doesn't. So the person you send it to MAY get charged for receiving the message.
They're just covering their own backs incase someone does get charged.
