How to get the location feature back on incoming callson my iPhone 5?

I accidentally hit "don't ask me again" on the location search feature on the incoming call. When asked to be reminded of a call when you change your location I selected no. I meant yes! How do I get the feature back so that when I decline my incoming calls I can elect to be reminded wje I leave my location
