Some people have their line set to always hide caller ID (e.g., by carrier request). If they call you as "Private," and you want to receive their calls, they must unblock their number. They can do this by:
A: Yes. When you block a number on an iPhone, it blocks them across Phone, FaceTime, and Messages. Unblocking them reverses this for all services.
iPhones have a feature that silences unknown callers automatically. If you are missing calls from private numbers (like doctors' offices or delivery drivers), check this setting:
To unblock a private number on your iPhone, you typically need to disable the feature or remove the number from your Blocked Contacts list if it was manually added . Because "private" or "No Caller ID" numbers don't show a specific digits, they are usually blocked by global settings rather than individual contact blocks. 1. Disable "Silence Unknown Callers"
If your iPhone is in and set to "Allow Calls From: Contacts Only," any private number will be silenced because it's not a saved contact.
Missing important calls because a number was blocked is a common annoyance. Whether you accidentally blocked a number while trying to silence a spammer, or you blocked a contact during a heated moment and now want to reconnect, unblocking a number on an iPhone is a simple process.
