Default Root an s3 and be able to use straight talk?

If i rooted my s3 using this method http://forum.xda-developers.com/gala...-root-t1957273. would i be able to use the straight talk sim and plan with my galaxy s3? There is a link to the straight talk card kit i plan to use because as of right now my phone is locked to verizon and my service with them has ended.
