No it's there. But it won't show unless you actually have some apps install that have the feature, like Sync.ME;
What these apps do is doing a identification search on unknown callers telling me who is actually calling and also doing a match towards "SPAM" databases and marking calls as potential SPAM if they get any hits.
So if lets say someone outside my contact list is calling me, Sync.ME will do a match towards their database, or the app that my company uses "Telenor MBN" will do a similar match towards 1881.no the biggest phone book database in Norway and if they get any matches I will get the contact name and information from their database so instead of only having a random phone number displaying I would get actual relevant contact details even when the number is not in my personal contact list.
This worked perfectly before, but it has stopped working completely with iOS 11.1.X and iOS 11.2. This functionality is simply not able to do anything it seems in iOS 11.2.
