Why Are You Getting So Many Spam Calls?
If your phone is constantly ringing with unknown numbers, it is likely because your personal phone number has been leaked, sold, or scraped. Here are the main culprits:
- Data breaches — hackers steal user databases from websites you've registered on and sell them on the dark web
- Data brokers — companies collect public information and phone numbers, packaging them for telemarketers
- Online registrations — many websites require a phone number for signup and share it with "marketing partners"
- Random dialing (War dialing) — autodialers call millions of number combinations sequentially to find active lines
Method 1: Stop Sharing Your Real Number Online
The best way to prevent spam calls is to stop giving out your real phone number in the first place. When signing up for apps, websites, or loyalty programs, use a temporary or virtual number instead.
By using a free virtual number service like text-verification.net, you can complete SMS verification without exposing your personal contact info to marketing databases.
Best for: Preventing future spam, signing up for one-time promotions, protecting online accounts.
Method 2: Use Built-in Smartphone Settings
Modern mobile operating systems have powerful, built-in tools to filter and silence unwanted callers automatically.
How to Silence Unknown Callers on iPhone (iOS):
- Go to Settings and tap on Phone
- Scroll down and select Silence Unknown Callers
- Toggle the switch to On
Note: This redirects calls from numbers not in your contacts, mail, or messages directly to voicemail.
How to Block Spam Calls on Android:
- Open the Phone app
- Tap the three vertical dots (Menu) and select Settings
- Tap Caller ID & Spam
- Enable Filter spam calls to prevent suspected spam calls from ringing
Method 3: Register on National Do Not Call Lists
Many countries operate government-backed registries that prohibit legal telemarketers from calling registered numbers. While this won't stop illegal scammers, it drastically cuts down on legitimate marketing calls.
- United States: Register at donotcall.gov
- United Kingdom: Register with the Telephone Preference Service (TPS)
- Canada: Register on the National DNCL
Method 4: Use Third-Party Spam Blocking Apps
If built-in settings are not enough, third-party apps offer database-driven spam detection that identifies and blocks spammers in real time. Popular options include:
- Hiya — provides advanced spam detection and caller profile details
- RoboKiller — uses answer bots to waste spammers' time and block incoming robocalls
- Truecaller — one of the largest global spam directories, though requires sharing your contact list
Method 5: Do Not Interact with Spam Callers
If an unknown call gets through, your behavior determines whether you get more calls in the future:
- Don't answer: Answering tells the autodialer that your number is active, leading to more spam
- Never press buttons: Robocalls often say "Press 9 to opt-out." Pressing any button confirms a human is listening
- Never say "Yes": Scammers sometimes record your voice saying "Yes" to authorize fraudulent charges

Frequently Asked Questions
Can spammers fake their Caller ID?
Yes. This is called "caller ID spoofing." Scammers use software to display local numbers or trusted company names to trick you into answering.
Should I call back a spam number?
No. Calling back confirms your number is active, and some scam numbers charge premium rates for incoming calls.
How does a virtual number protect me?
By using a virtual number for online sites, you keep your real mobile number offline. Even if the website leaks the database, only the virtual number receives spam, keeping your real phone quiet.
