As others have said, Yes. Nothing to do with your phone or ROM. Your phone will indicate that it has received a message when the network actually sends it to the phone (unless your out of signal coverage, at which point you will receive them when you receive a signal again).

Not receiving the message for hours after it has been sent is a direct indication of a network issue. Call your company's tech department and make them aware of it so that a trouble ticket can be put in.
