I can't unlock my phone

I have a Rogers Samsung Focus and I purchased an unlock code. When I insert my Fido sim card it doesn't prompt me to enter a unlock code but my phone says "sim error". I tried using the secondary option "#7465625*638*CODE#" and it doesn't do anything not even invalid code. Am I missing a step? Please help
that's strange. rogers & fido are basically the same network now. I've been able to swap sim cards between them without unlocking. maybe there is a problem with your sim. sorry I cant help more.
