How do I unlock a straight talk Samsung galaxy s3 so I can bring it to cricket?

[AC Question]

I bought a straight talk Samsung galaxy s3 about 6 months ago. After recent issues of them charging me twice each month I decided to switch carriers. They would not let me keep my number and said if I want to unlock my phone I have to pay for 6 months right now which totals 270 plus tax. I refused and was hoping there is a way to use it with Cricket without straight talks help

Welcome to Android Central. If Straight Talk has the phone locked to the service, then to my knowledge, no. This can't be done.
