If you are unable to receive calls from unknown numbers on your iPhone SE (3rd generation), one possible reason could be that Silence Unknown Callers is enabled.
To check this setting, go to:
Settings → Apps → Phone → Silence Unknown Callers
If this option is turned ON (ticked), calls from numbers that are not recognised or saved in your contacts may be silenced rather than ringing normally.
A few important points to understand:
- The calls are not necessarily blocked. They are silenced and generally do not ring on your iPhone.
- Recent Calls: These calls should still appear in the Phone app's Recents list.
- Voicemail: If the caller leaves a voicemail, you should be able to find it in your Voicemail section, provided voicemail is supported and configured by your carrier.
- Known callers: Calls from saved contacts and certain numbers recognised by Siri Suggestions or other recent interactions may still ring normally.
Please note that you have not explicitly mentioned whether this setting is enabled or disabled in your post.
Also, your post does not clarify whether:
- Calls from unknown numbers are completely missing from your Recents list.
- The calls appear in Recents but your iPhone does not ring.
- Callers are being directed to voicemail.
- You receive calls from saved contacts without any difficulty.
These details are important because they help narrow down the cause. Silence Unknown Callers is just one possibility; other settings, such as Focus modes, carrier-level call filtering, or call-blocking services, could also be responsible.
Please check this setting first and clarify what happens when someone calls you from an unsaved number.
