Pls why am I unable to call the registered number within my cug police plan and how are you going to help me?

Hi Olawuwo, it may be a temporal system issue, you can power off and power on your phone and try it again. If the issue persist, you may need to check your CUG status or the Status of the person you are calling if the person is still a member of the CUG. You can contact your Telecom master or the person in charge of the CUG to check.
