Caller ID not working on iPhone 4S

Just got an iPhone 4S today. Also switched from AT&T to Verizon. For some reason, I am only getting caller ID on contacts that have the country code added to their numbers. I turned off International Assist, and it didn't do anything. When I add the country code to the number in the Address Book, the caller ID works just fine.

Is there any way to fix this? Or is there any way to add all the country codes at once instead of doing it manually to 400+ phone numbers?

If you close the caller ID screen as it is it will stay on:)

Hi all, in my case the service provider had disabled the Caller Line Identifier option in their system. Spoke to them to check CLI and it was N. They set it to Y.

It happened after I travelled overseas and used an AT&T SIM and then had to get a new SIM when I got back home in Austrralia (as I lost the original - they are so small.)
