Does Verizon Wireless charge for canceling a Data plan?

Suppose I have a smart phone, but I found out after a month I don't want the data plan anymore, and want to go back to my regular phone, will I be charged an fee for canceling the data plan but still keeping the voice plan? I looked through Verizon Wireless; Terms and Conditions and couldn't find anything related to that.
