There are methods to block calls from unknown or suppressed caller IDs on an iPhone. Here’s how you can do it:
Blocking Unknown Callers:
- Open Settings on your iPhone.
- Scroll down and tap on Phone.
- Tap on Silence Unknown Callers.
- Toggle the switch to enable this feature. This will silence calls from numbers not in your contacts, sending them straight to voicemail.
Blocking Specific Numbers:
- Go to your Phone app.
- Find the recent call from a foreign number or suppressed caller ID.
- Tap the (i) icon next to the number.
- Scroll down and select Block this Caller.
For suppressed or hidden caller IDs, unfortunately, there isn’t a direct method to block them specifically on the iPhone. However, using the "Silence Unknown Callers" feature can help in reducing unwanted calls from hidden numbers, as long as they aren’t in your contacts.
