A method, system and computer-usable medium are provide for managing the Open Channel for IMS command correctly the UICC to have knowledge about the specific status codes the ME received from IMS. This knowledge allows the UICC to make a smarter decision on what it attempts to do to access IMS. Accordingly, the UICC is provided with detailed information about the status codes from the IMS service to allow the UICC to make an informed decision. If the UICC does not have such knowledge, it is possible that the UICC will send potentially unwanted commands to the ME to establish access to IMS.
