How do you block unknown calls on iPhone 12?
If the caller is deliberately hiding his caller ID using a method like Star 67 then the call will not be blocked as your iPhone won't have an incoming number to match with the list of blocked phone numbers.May 19, 2014
Can you block all no caller ID on iPhone?
“No Caller ID” means just that - the caller overtly blocked their ID from being displayed. ”Unknown Caller” means a caller ID was provided but not recognized.Aug 18, 2020
How can I block my phone from receiving unknown calls?
no, as no number is associated with the call for it to be blocked. Not on the phone itself but most cell carriers have a feature to block these calls. Check with your cell provider and you may find that it's already a service that is part of your calling plan and they can simply enable it for you.Mar 28, 2014
