Correct, 2480 and 2481 are the default ports for Mobilink (mlsrv16.exe process). Check the mlsrv_err.log in the C:\SAP\MobilePlatform\Servers\UnwiredServer\logs directory for errors. If there is a port bind issue, use the command "netstat -ao | findstr 2480" to find out which PID holds the port (if any) as I have seen where another piece of software was holding the port. You can cross reference that PID with the processes in Windows Task Manager.
This maybe much more difficult than can be handled in SCN though and you may need to open an incident. Try the above first though.
