I have tried 0000 and 1234 but it says password error. So what should be the password to bar all incoming calls in sony ericsson w660i. Please help to solve this issue..
When you select Restrict Calls under Manage Calls in the settings of your W660, the password that it is asking for is the PIN2. That is what you would need to ask your service provider about.
Restrict calls only restricts outbound calls though. It sounds like you want to modify the Accept Calls setting. Select Accept Calls under Manage Calls. You can create a list of Contacts that the phone will accept calls from, and you don’t need a code set it up.
