Other tips for reducing spam and robocalls

Blocking a few numbers helps, but there are more ways to cut down on unwanted calls and messages.

Use Silence Unknown Callers

This feature sends calls from unknown numbers straight to voicemail. However, if you don’t have the number for your doctor’s office or a restaurant saved, you could miss a confirmation notification.

1. Go to Settings > Phone.
2. Tap Silence Unknown Callers and turn it on.

Report spam to Apple

If you get a spam text in Messages, you might see a “Report Junk” option. Tap it to help Apple block similar messages in the future.
