What happens if you send a text to a blocked number

You can easily block phone numbers on your iPhone or iPad if you do not want to get calls or texts from those numbers. For example, you may want to block the same telemarketers that keep calling you, or there may be someone in your life you never want to contact again. Blocking enables you to take control and decide who can contact you. Sometimes, however, you may wonder if you can call or text the people you blocked. You may further wonder if you would need to unblock them before sending a text, iMessage or placing a call. In this article, I provide answers to these questions.

Can you text a blocked number?

When a blocked number texts you, you won’t receive the message. However, you can still text the number, and the other person will receive the message. If they decide to respond to your text, you won’t get the reply. The reply won’t be delivered so long as the number is blocked. However, if you are sending an iMessage, your message won’t say Delivered or Read, as it would normally, because the Message app won’t get anything back to confirm the delivery or read receipt from the other party. You will still be able to send the message as an iMessage, so the message will have a blue bubble instead of green one if you are texting an Apple device.

Can you call a blocked number?

A blocked number can call you and leave you a voicemail, but your phone won’t ring, and you won’t receive any notifications; you won’t know about the call until you check your voicemail. When the blocked person calls, they won’t know that they are blocked. You can still call your blocked contacts. Their phone will ring as it normally would. It won’t go straight to voicemail. If they answer the phone, you can talk normally. You do not have to unblock them first to call a blocked contact.

How to block or unblock a number or contact

As I explained above, the blocking feature only blocks incoming calls or texts. Your outgoing calls or texts won’t be affected.

Your iPhone or iPad makes it very easy to block and unblock people or numbers. You can use the Phone, FaceTime or Messages apps. Just follow these steps:

• From the Phone app: Open the Phone app, tap Recents, then tap the Info button (i) next to the phone number or contact that you want to block. Tap Block this Caller.
• From FaceTime: Open the FaceTime app and tap the Info button (i) next to the phone number, contact, or email address that you want to block. Tap Block this Caller.
• From the Messages app: Open the Messages app, then open the conversation and tap the contact at the top of the conversation. Tap the blue info button (this one looks like a blue dot with a person icon inside). Tap Block this Caller.

If you want to unblock a number, simply repeat the same steps, but this time, tap Unblock this Caller. You can also manage your blocked list:

One great thing about iPhones is that they make it simple to block nuisance callers. If you keep getting those annoying automated calls asking if you’ve been in a recent accident, then you can hang up, go to the call log and block that caller – so long as they’re not withholding their number.

But what if it happens in reverse? If you find that you can’t get through to a particular person after multiple attempts, is there a way to tell if they have blocked you on their iPhone?

Similarly, if they don’t reply to your messages, is it because you’re blocked? Maybe they have Do Not Disturb enabled? Or are they simply busy and not had time to respond?

Before we get to the tips, know this: it is tricky to know for sure if you have been blocked. But hopefully, you’ll be able to find out one way or another.

The most likely scenario is that you’re being paranoid, and the other person just hasn’t got around to replying to your message or calling you back just yet. Give it a few hours and try again.

But, if it’s not all in your mind, here are some signs that you might’ve been blocked on an iPhone. These are just tips though; if you need to be 100 percent sure, you’ll need to ask them in person.

What happens to a blocked phone call?

To test what happens to a blocked call, we blocked a number and monitored the experience on both phones. When calling from the blocked number, the caller hears either one ring, or no rings at all, but the other phone remains silent. The caller is then informed that the recipient isn’t available, and is diverted to voicemail (if that service is set up by the person you’re calling).

There doesn’t seem to be a reason why the number of rings varies, but if you hear two or more, you can be pretty sure you haven’t been blocked.

Note that you can leave a message if someone has blocked you, but the blocker will never be notified of the message. It does appear at the very bottom of their voicemail list in the Blocked Messenger section (if they’re on a carrier that supports visual voicemail such as O2 or EE), but most people probably won’t check there.

What happens to a blocked text message?

Texting someone who’s blocked you works as you would expect. The message sends as normal, and you don’t get an error message. This is no help at all for clues.

If you have an iPhone and try to send an iMessage to someone who has blocked you, it will remain blue (which means it’s still an iMessage). However, the person you’ve been blocked by will never receive that message. Note that you don’t get a ‘Delivered’ notification like you usually would, but this in itself is not proof that you’ve been blocked. They could simply not have any signal, or an active internet connection, at the time you sent the message. 

What about Do Not Disturb/Focus modes?

Apple’s Do Not Disturb tech, which has recently blossomed into multi-use Focus tech, essentially gives users complete control over incoming notifications, calls and messages, essentially dictating who and what they want to be notified about when a focus is active. If you’re at work, for example, you may choose to block all incoming texts, calls and notifications from all but work colleagues to help keep you distraction-free.

That could be a reason why you’ve not been able to get through to your friend or family member. Apple does give users the ability to share their Do Not Disturb status via the Messages app, so you could take a look at the message thread to see if Do Not Disturb is enabled on the recipient’s phone, but status sharing isn’t enabled by default and, thus, not everyone will utilise it.

If your calls and texts are being blocked via a Focus/Do Not Disturb mode, give it a few hours before you try to contact them again.

OK, so have I been blocked or not?

The call is the best source of evidence to determine whether or not you’ve been blocked by an iPhone user. The key is that you will always be diverted to voicemail after exactly one ring – if they were declining your call, the number of rings would vary each time, and if the phone was switched off, it wouldn’t ring at all.

Also keep in mind that Do Not Disturb will also cut you off after exactly one ring, so don’t get too worried if your calls aren’t going through at 3am. There is a Do Not Disturb setting that allows the user to specify that repeated calls are allowed through so you could always try again right away – just make sure your call is urgent, or they may block you for real this time!

Finally, we would like to repeat that this isn’t an exact science, so don’t make any angry scenes without knowing for sure. Also: chill out, relax, and try not to worry about it. If they’ve blocked your number, hey, who needs them?
