How to Reduce Spam Calls and Texts

By , Cyber Security trainer LinkedIn Published: Last updated:

Reduce spam calls and texts with built-in filters: silence unknown callers, report junk SMS, register on official Do Not Call lists where you live, and never engage with spam (callbacks and “YES” replies confirm your number). Combine filters with good OTP habits.

Quick steps

  1. Enable Silence Unknown Callers / spam protection on iOS/Android.
  2. Use your carrier’s spam filter if offered.
  3. Report junk in the Messages app.
  4. Register on official Do Not Call lists in your country when available.
  5. Do not return missed spam calls.

Why this matters

Rachel in New York silenced unknown callers. Mohan in Nashik reported spam SMS and stopped replying STOP to shady senders that were not real carriers.

Engagement teaches spammers your number is alive.

What you need to know

Tools: OS spam filters, carrier tools, official DNC registries. Habit: do not callback random missed spam.

Spam reduction

  • Silence unknown callers — Helpful
  • Reply to spam with anger — Confirms number
  • Official DNC registration — Helpful where available

How to do it (step by step)

  1. Enable Silence Unknown Callers / spam protection on iOS/Android.
  2. Use your carrier’s spam filter if offered.
  3. Report junk in the Messages app.
  4. Register on official Do Not Call lists in your country when available.
  5. Do not return missed spam calls.
  6. Keep refusing OTP/money asks regardless of filters.

Example: Rachel silences unknowns

Rachel enabled Silence Unknown Callers; friends in her contacts still rang normally.

Mohan reported SMS junk for a week and saw fewer parcel-fee texts.

Both still verify real bank calls by dialling back on card numbers.

Common mistakes

  • Answering and arguing with robocallers.
  • Tapping links in spam SMS.
  • Turning off all filters because one false positive happened.

Trusted places to check

Quick revision

  • Use OS/carrier spam tools.
  • Do not engage spam.
  • Still verify real banks yourself.
