parental control texting

Straight Talk is the parental control?
My parents want to keep my brothers and I safe and very limited with our phones, pointing how they were in an emergency situation, but they are learning how not having a lot of minutes affects our social life when the text you want search multiple prepaid phone companies with unlimited SMS plans. I was in helping you find the prepaid phone plans with unlimited text messaging, and met with Straight Talk. They do not want us to have a camera on our phones, so I was wondering if there was any way they could block the camera video cameras and mobile Internet browsing —- And, if possible with a plan for unlimited texting. Thanks a lot!
If it is a phone for my son or something, or remove the camera somehow obscure or permanent adhesive on the camera to be off:)
