There are many reasons to want to block specific numbers on your phone. Whether it's nuisance spam callers, or a particularly persistent ex you no longer want to talk to, the humble Block option is a phone mainstay. It used to be you'd need to contact your carrier to stop a particular number from calling you, but thankfully, it's a lot easier to block numbers in this day and age.

What You Need

  • An iPhone or Android phone

Blocking numbers is now built into both Android phones and Apple iPhones, and it's easy to access too, being available directly from your phone dialer. No, you don't need to download a third-party app, or dive deep into your settings. Here's how to block a number on iPhones and Android phones.

How to block calls on an iPhone

You've been able to block contacts and callers on iOS since iOS 7, which means it's available to absolutely everyone using an iPhone — unless you're still using an iPhone 3GS or older. If you are, well, we highly recommend upgrading your iPhone. You won't regret it.

Step 1: To block a caller, head to your Dialer app.

Step 2: Tap Recent.

Step 3: Choose the number or contact you want to block.

Step 4: Scroll down and select Block this caller.

If you want to block an existing contact that isn't in your Recent list, follow these steps.

Step 1: Open the Dialer app again.

Step 2: Choose Contacts.

Step 3: Find the contact you want to block, and select them.

Step 4: Select Block this caller.

How to block calls on an Android phone

Blocking calls on an Android phone is just as easy as on an iPhone, though it's worth noting that different manufacturers will have slightly different processes to follow. However, the general idea will be similar, so you should be able to find the blocking option relatively easily.

Step 1: Open the Dialer or Phone app.

Step 2: Find the contact or number you want to block, and select their icon to open the profile.

Step 3: Choose Block numbers.

As mentioned, it can be slightly different on different phones. Here's how the block process looks on a Samsung Galaxy phone.

Step 1: Again, open the Dialer app and find the contact to block.

Step 2: This time, select it to open it, then choose the "i" button.

Step 3: When the profile is open, select Block at the bottom, and then Block again to confirm.

How to manage blocked numbers on an iPhone

Want to trim down your blocklist, or remove someone now that you've made up? It's easy to remove numbers from your block list. You can head to the individual contact in your contact list and unblock them using the same process as blocking, but if it's not a number you have saved, you can still find them elsewhere.

Step 1: Head to the Settings app.

Step 2: Open Phone or Messages.

Step 3: Find Blocked contacts and select it.

Step 4: You'll find a full list of your blocked numbers and contacts here.

Step 5: To remove one, tap Edit, then the minus sign by the number or contact, then Unblock.

How to manage blocked numbers on an Android phone

As with iPhones, you can simply backtrack the blocking process to unblock a contact, but there's also a list of blocked contacts and numbers you can access to quickly see how many you've blocked.

This process may be slightly different on other manufacturer's phones (we used a Google Pixel for these screenshots), but in general, this guide should be close enough that you can find your way around without much issue.

Step 1: Open your Dialer or Phone app and open the Settings menu by choosing the three-dot menu at the top-right corner.

Step 2: Select Blocked numbers.

Step 3: Now, you can see a full list of your blocked contacts. To unblock one, just select the X by their number, and then confirm by selecting Unblock.

Just like that, you've becoming a number-blocking pro. Blocking numbers on iPhones and Android phones is a much simpler process in 2024 than it used to be, and now, you know everything about it. Good luck and happy number blocking!

Adobe made the best iPhone camera app you haven’t tried yet, and it’s free
Indigo camera core controls.

A year ago, a rather interesting camera tool came out from the house of Lux, makers of the fantastic Kino and Halide apps. The tool is called Process Zero, which essentially ripped the images of Apple’s computational adjustments and delivered a pristine photo. 

I even compared the current-gen iPhone with the iPhone 6s and realized the ills of computational photography. What I noticed repeatedly was that algorithmic processing makes the photos look sharper and more colorful, but they aren’t always accurate. And in doing so, they lose their natural charm.

This one iPadOS 26 feature has me excited for the iPhone Fold
Semi-open state of a foldable iPhone concept

Samsung is set to launch the seventh generation of its Galaxy Z Fold book-style folding phone this Summer, but its biggest rival is yet to show its folding phone hand. Apple has long been expected to unveil an iPhone Fold, and the latest rumors suggest that it will launch next year.

I’ve used almost every folding phone released globally, with some exceptions for extremely obscure ones. While I've always been curious what an iPhone Fold would look like, I was fairly certain that Apple shouldn't build it, as I wasn’t sure they could deliver on one necessary feature.

These three iOS 26 beta features are my favorite so far
The Liquid Design lock screen on the iOS 26 developer beta 1 running on the iPhone 16 Pro

For fans of the Apple ecosystem, it’s been an incredible week. Apple’s annual WWDC 2025 keynote revealed a whole new Liquid Glass design that’s unified across all its platforms. Also unified across all platforms is the numbering scheme, with iOS 26 designed to represent the year of release… plus one. 

The new platform doesn’t deliver one of the key things I asked for — multitasking, which is available on iPadOS 26 — but it does bring several new features that make the iPhone far more usable.
