In google only my contacts are displayed in ur contact list. I would suggest you to remove all unnecessary contacts in the my contacts group. Rest all contacts are synced as well but they will be available in ur email address book only. #Mohit service provider has nothing to do with activating facetime. I activated facetime on a BSNL sim. Make sure wifi is on and your phone number is automatically listed in the about phone. If the phone no is a forced one it will not activate.
In my Iphone 4s, under settings < phone < my number is "unknown". How do I resolve this? And I don't see any "my number" option in "About" option under Settings.
