my unlocked verizon phone has not activated under straight talk

[dclingensmith]

I got Verizon to unlock my iPhone 43 (model 1387), we inserted a micro sim that we ordered from Straight Talk (i think it is an AT&T carrier one, not sure), called straight talk to activate the micro sim and phone account, etc.. now the phone won't work. It keeps saying it needs to be activated. Straight Talk said it could take 2hrs to 2 business days to activate, and the phone isn't working with the old Verizon micro sim. Anyone ever run into this problem?

Verizon uses CDMA not GSM the sim card in a Verizon device is only so it can use there 4g lte / international services.
