Spam calls and messages aren’t only annoying but sometimes carry the risk of identity or digital theft. That’s why it’s important to be vigilant.

One of the easiest measures to outsmart this situation is to block phone numbers that send spam calls and SMS. Follow along as we break down phone number blocking and the steps to block a phone number on your iPhone.

What Happens When You Block a Number on iPhone?

One of the most common questions people have around phone number blocking is what actually happens when you block someone on your iPhone.

The short answer is that when you block someone on your iPhone, they can no longer reach you via calls, iMessage, or FaceTime. Basically, their calls end up in your voicemail. When a voicemail is sent, it ends up in the Blocked Messages folder at the bottom of your voicemail list.

iMessage and regular text messages, on the other hand, appear to end up with the sender but never arrive on your device. Similarly, FaceTime calls appear to be sent, but you don’t receive them.

For any of these situations, the sender, whose number you’ve blocked, won’t be notified about the same. They would, however, eventually come to know that you’ve blocked them since you’d never respond to their communications. Also, you should note that outgoing calls and messages from your end will still be forwarded to the other number or contact since you have blocked the sender.

Third-party apps, such as WhatsApp and Telegram, work even if you block someone’s number on your iPhone.

In the Messages app, you can report iMessages that appear to be spam or junk. The Report Junk link is visible if you receive an iMessage from someone not saved in your Contacts.

Tap Report Junk, then tap Delete and Report Junk. The message will be forwarded to Apple, along with the sender's information.

When a message is reported as junk, it does not prevent the sender from sending another message. Block the contact if you don't want to receive these messages.

On iPhone, take a look at iMessage. Once a message has been delivered, you will receive a 'delivered' confirmation. If you think someone has blocked you, look for confirmation in their messages. It should have a 'delivered' status if you know it was received and responded to. You could be blocked if you do not see that "delivered" notification under subsequent messages
