Got my iphone 4 days ago, caller ID worked for the first 48 hours then started displaying UNKNOWN for all incoming calls afterwards. (These are calls from people on my contact list)
Tried resetting and changing cellular bands, nothing has worked.
Any tips? Or do I need to return this phone?
Solved! Go to Solution.
Hi there, could you please confirm what iOS version you on ? Have you enabled Show My Caller ID option in
Generals>Phone>Show My Caller ID toggle set it on and reboot your phone.
hope it helps
I'm also having the same problem where all my incoming calls are showing up unkown. Is there a way to fix this?
- Recently upgraded to iphone 6s
- Caller ID was working the past week & are now unknown
