How to stop spam calls on iPhone

Why it happens: people-search sites publish phone numbers next to names, addresses and relatives, and sell that data to anyone. Callers buy those lists.

On iPhone: Settings > Phone > Silence Unknown Callers sends unknown numbers to voicemail. It quiets the ring, but it also silences real calls from doctors and deliveries, and it does nothing about why they keep calling.

What actually helps: get your number taken off those sites, then keep checking, because they re-list people every few months. That is what TrueSearch Protect does: removal requests to 28 sites, re-checked every 90 days. Removal cuts the lists callers buy from; it will not stop every robocall, since some dial random numbers.

Free scan: enter your number and see which of 28 people-search sites list it in 10 seconds.
