Carriers normally fulfill the request during their regular business hours before 6 PM. If it is after that time, simply turn it off and back on, if that does not work, perform a Hard Restart/Reboot of your phone. Here are instructions for Android and here are instructions for iPhone.
If that does not work, simply contact our Port Support who will verify with our carrier, if the port has been completed. If it has been fully completed and removed for our carrier, you will need to contact your phone provider for further assistance.
