One of the most annoying things about carrying a phone in your pocket is unwanted phone calls or texts. Thankfully, your iPhone allows you to block phone calls and text messages from any number on your device in a few simple steps. You can block contacts already stored in your phone or unknown numbers you’ve not added as contact.

Whether they’re spam calls, texts, or someone you don’t want to talk to anymore, we’ll show you how to block them on an iPhone 15.

When you block a number on an iPhone, the owner of that phone number won’t be able to successfully text or call you, and they won’t be informed that they’ve been blocked.

The process of blocking a number on an iPhone is the same, so the methods in this guide will work on all iPhone 15 models including iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max .

Open the Phone app on your iPhone 15.
Select the "Recents" tab to see the calls that have come into your phone in chronological order.
Tap the blue ”i” icon next to the number you want to block.
Scroll down and tap "Block Caller." A pop-up will appear informing you that you will not receive phone calls, messages, or FaceTime from people on the block list..
Confirm that you’d like to block the phone number by tapping the "Block Contact" button.

That’s all there is to it! Blocked numbers can be found in the Phone app’s Settings under "Blocked Contacts."

Open the text message from the number or contact you wish you block.
Tap the number or contact at the top of the message, then click the small info icon.

How to Tell if Someone Blocked Your Number on iPhone

There’s no definitive way to know if someone has blocked your phone number—you won’t be notified—but there are some clues to look for that may suggest it’s happened.

First, if your calls always go straight to voicemail or only ring once before going to voicemail, it could be a sign of being blocked. A typical call will ring more than once. However, the recipient may have simply turned off their phone or put it in Focus mode.

You can also try to leave a message and see if they get back to you. If your number has been blocked, they won’t receive the voicemail. Again, this is not a surefire way to know if you’ve been blocked. They may just be slow to respond.

For better or worse, you’ll have to figure it out on your own or ask friends and family to do reconnaissance for you. If you suspect you’ve been blocked, it’s best to respect their wishes.
