Default A way to use the phone without a SIM card?

I'm looking to flash to straight talk using a donor phone, but I can't dial anything because I lack a SIM card. Is there a way to bypass the SIM check and just use cdma and 3g?

What is necessary to make this happen? If it's impossible without a SIM, do I just need a Verizon SIM card?

I really want to use this as my phone, but until I can get it to dial I'm dead in the water.

I have my fascinate on St right now, but have a brand new donor phone as well if I need it.

Anyone here who can help? I have the software, I just need to get over this hurdle as I've no idea where to find a previously activated SIM card.
