Can Fido sim cards be used with a Rogers phone?

[Genie]

I have a Fido phone/sim card, but I recently found a phone I really like from Rogers Wireless and I'm wondering if a Fido sim card can be used with a Rogers phone. I'm asking because Rogers bought Fido so they're technically the same company, right?
