To use two different carriers, your iPhone must be unlocked. Otherwise, both plans must be from the same carrier. If a CDMA carrier provides your first SIM, your second SIM won't support CDMA. Contact your carrier for more information.
If you have an enterprise or corporate cellular service plan, check with your company administrator to see if they support this feature.
