After ios11 upgrade, contacts are no longer recognized by phone numbers

I just upgraded my iPhone7 to ios11, and quickly noticed that when I go to the phone app, I see the list of recent calls and favorite numbers as showing phone numbers only.. without the contacts names. Even when somebody calls me (and they are in my contact list with the correct phone number + country code), the name isn't shown at caller ID... only the number, with few names being suggested as "Maybe: person name".

It was working well before the upgrade, and I'm sure I have the numbers correctly typed, WITH correct country codes. Even when I receive a call, I go to recent calls and create a new contact out of the number that I just received.. but all in vain as it still doesn't show the name in recent calls or when the person calls again.

I have a Brunei phone number (country code +673) with DST sim card, and sometimes few contacts show the title "Brazil" below the phone number (although the number says +673-xxxxxx), so it indicates a strange bug confusing the two countries since they both start with "Br". I even went to the authorized service center to check how to fix this, and they told me that many people are coming with the same complaint, and still there is no solution for that.


The current situation is making it very difficult to use the phone when receiving phone calls since one has to answer the call without knowing who is calling. Hope apple can quickly address that and fix the problem.

I discovered that either the update or something else had changed my settings to “iPhone” so non-iPhone users were showing up as “maybe” and also every text was going out as data! Instead of using my network connection. I just had to turn that off in the settings. We have 5 users so it ate thru a lot of data before we figured it out!!! Very annoying.
