See who is calling before you answer. C

Don't worry if numbers do not show yet. Caller display lets you see who is calling before you answer, when your phone and line support it.

Quick answer

Caller display shows the phone number of the person calling on your home phone screen before you pick up.

More detail

Caller display is included on most Simple Telecoms lines at no extra charge. Your home phone must have a screen and the feature turned on.

Some withheld or international numbers may show as unknown. Scammers can fake caller display, so treat unknown numbers with care.

You can set up caller display after your line goes live if numbers do not appear straight away.

Things to understand

  1. The calling number is sent to your phone when someone rings you.

  2. Your phone handset must support caller display and have it switched on.

  3. Withheld numbers may show as unknown or private.

  4. Caller display helps you decide whether to answer.

  5. It is not proof a call is safe, because numbers can be faked.

Common mistakes

  • Assuming every phone will show numbers without checking handset settings.
  • Trusting caller display alone to prove a call is from your bank.
  • Forgetting to enable caller display on a new phone.
