Most of us carry our phones with us wherever we go, but there are some downsides.

Having your phone with you means it can be hard to escape unwanted calls. Nuisance callers will often block their number in the hopes that you’ll pick up out of curiosity. No caller ID calls are rarely from anyone we want to speak to, however.

To silence unknown callers on iPhone:

  1. Open the Settings app on your iPhone.
