Reduce unwanted calls on your phone
Step 1 of 5: End a suspicious conversation
Hang up if asked to reveal security codes, install remote-access software or move money urgently. Do not rely on the caller’s displayed number as proof of identity.
✓ Step complete. You can practise it again.
Step 2 of 5: Block a specific number
On newer iPhones, review Settings, Privacy & Security, Blocked Contacts; older versions offer Block this Caller in a recent call’s details. Android alternative: in Google Phone, open call history and choose Block/report spam for the number.
✓ Step complete. You can practise it again.
Step 3 of 5: Review screening choices
Check your phone’s call settings for available screening, spam identification or unknown-call controls. Features depend on model, software, region and network. Read what each control does before enabling it.
✓ Step complete. You can practise it again.
Step 4 of 5: Keep genuine callers reachable
Ask a trusted contact to call and check that it rings. Review voicemail and missed calls regularly. A clinic or delivery driver may use an unfamiliar number.
✓ Step complete. You can practise it again.
Step 5 of 5: Verify any important claim
Call the organisation through its genuine app, card or official website. If you disclosed banking information or made a payment, contact your bank promptly using its genuine number.
✓ Step complete. You can practise it again.

A common question.
Why do calls continue after I block a number?
Callers can change or spoof numbers. Blocking limits that displayed number; it does not establish who is calling or remove all future scams.
