Verizon SGS3 to Straight Talk for unlimited talk, text, data, and tethering

[AC Question]

Because my Verizon S3 has tethering capabilities, does anyone know if I can switch to straight talk and keep all of my features? I want to keep my number and be able to tether, for I am a college student and do homework and studying on the go. I am past tired of getting screwed by Verizon and would like unlimited talk, text, data, and tethering capabilities. Is this possible or am I living in a dream world? If it's possible will the data speeds even be worth it?
