How to block spam calls on iPhone (2023)

Block spam calls on iPhone

In a world where swindlers and sniffers look out for their next victim, they use any means to achieve their aim. And that includes buzzing your phone with spam calls and messages.

Knowing how to prevent such people from contacting you is essential. You can achieve this by blocking spam calls on your iPhone. Besides strangers, you might also want to avoid specific people’s calls at a particular time.

In this article, I’ll show you how to block spam calls on your iPhone and stay in your lane.

Note: While you’ll still be able to call and message a blocked contact, you won’t receive calls, FaceTime, or messages from it anymore. However, the blocked number can drop you a voicemail if you want, which you can only listen to when you visit your voicemail inbox.

How to block unwanted calls on iPhone

Blocking unwanted calls is straightforward on the iPhone.

You’ll consider two scenarios when blocking a phone number; you’ve already stored the number on your contact, or it’s strange (probably a spammer) not in your contact book.

The number is in your contact book

  1. Open the Phone app.
  2. Go to Contacts at the bottom of the screen.
  3. Select the contact you want to block.
  4. Tap Block this Caller → Block Contact.

  1. Go to your iPhone Settings → Phone.
  2. Next, tap Silence Unknown Callers.
  3. Toggle on the switch to the right of Silence Unknown Callers.

Q. Is there a setting to block spam calls on the iPhone

While there’s no inbuilt setting to identify and block spam calls automatically on the iPhone, you can block them manually or better install third-party spam call filters from the App Store. Any of the apps I recommended earlier works. So you might want to check them out.

Q. What is the best spam call blocker for iPhone?

Picking the best spam call blocker depends on your preferred features. There are many of them out there. Some are network-specific, while others work, regardless of your network provider. You can pick from any of the apps I recommended above.

Q. Why do I keep getting spam calls on my iPhone?

You’re more exposed to receiving frequent spam calls if your phone number is all around the place online or if you share it with anyone you’re unfamiliar with. Someone might’ve also shared your number in a public place. To prevent this, you should avoid leaving a personal contact number on your public profile on social media like Facebook, LinkedIn, and Instagram, among many others. But if you must drop your contact, you can use your business phone number instead.

Q. What to do if I keep getting many spam calls?

One of the best ways to block spam calls from individuals and robocalls is to use spam call filters. You can also take action from your end by blocking such contact outright. Contact your network provider to report suspected spam calls if things get out of hand.

Blocking spam calls on the iPhone is easy since Apple provides an easy way to go about it. And thankfully, as I pointed out earlier, third-party spam call filters make the process smoother if you don’t want to keep reinventing the wheel.
