TOP 7 Call Blocker for Android and iPhone [Tested]

We get many calls every day. Some of them are crucial, while others are there to irritate you, such as unknown calls from telemarketers or spam. Thankfully, there are numerous apps here to stop and block unknown calls or spam calls. Now, this article will dive into the best call blockers for Android and iPhone.

👍Editor's Recommendation:

If you just need to block spam calls, we recommend Call Control, Truecaller, and Hiya Spam Blocker.
To block unknown numbers, Phone Call Blocker, Should I Answer, or Call Blacklist deserve a try.
Among them, Call Control and Truecaller do both well.
Perhaps you may want to remotely block calls for your family members, I'd like to introduce AirDroid Call Blocker for you.

Does Android and iPhone Have a Call Blocking Feature?

Yes. Whether you're using an Android or iPhone, they both boast the feature to block or silence unknown callers and specific ones you chose. Here's how you can block unknown numbers:

For Android:

Step 1.Open the "Phone" app and tap the "three dots" in the top right.
Step 3.Select "Settings" and then "Block numbers."
Step 4.Turn on the "Block unknown/private numbers" switch.

For iPhone:

Step 1.Go to "Settings" to locate the "Phone" app.
Step 2.Select "Silence Unknown Callers" and turn on the toggle.

Despite the built-in unknown call blocking function, it is not robust enough to block unknown callers, especially for iPhone! During my test, non-contacts could still reach out to me through phone calls, and I figured out that this was because they were on my recent calls list.

Therefore, we're here to offer you some call blockers to block calls more effectively or flexibly. Scroll down to see!
