I have this samsung sph-a620 cell phone and I want to use my cricket service on it . How do I do that?

Answers:

Im pretty sure that you can%26#39;t.. Cricket uses thier own sim cards that aren%26#39;t compatible with any other phones. I had Cricket for a month and I hated it! I stopped paying it and they keep sending me bills..
