Dial in the following codes on your phone (without pressing call). If the code works a hidden menu will apear. Find the option 'Port Check Test', and set it to 'Enabled'. It is usually in the top menu or in the 'SVC Menu' submenu.

In case you can not get to the hidden menu, or the hidden menu does not contain the option 'Port Check Test', try Factory Reset on the phone.
