One way to test this situation is to leave a voicemail and wait. If you've been blocked, the recipient will not receive a notification and won't be able to respond. If you don't receive a returned call or text message within a few days, there's a good chance you may be blocked.
If you think you've been blocked, try calling the person's number from another phone. Use your work phone, borrow a friend's phone; it doesn't really matter. The point is, if you can't reach a person on your phone, but can reach them on another phone, there's a good chance you've been blocked.
When you block a contact over Android or iPhone, they will still be able to send you text messages. These messages will not show up on your phone but the sender will see the messages as sent. They won't know that they've been blocked.
Here's a great tip for how to tell if you're blocked on iMessage: Look underneath the last text you sent. If you're blocked, you won't see "Delivered" below the most recent text bubble. However, with recent security updates, this tip depends on your iPhone software version.
A red flag that you've been blocked is when you don't see the delivery status or the read receipt at all. The message you just sent will still be in a blue bubble, but it will have no delivery status below it – not even a "Not Delivered."
If an Android user has blocked you, Lavelle says, “your text messages will go through as usual; they just won't be delivered to the Android user.” It's the same as an iPhone, but without the “delivered” notification (or lack thereof) to clue you in.
Count the rings before voicemail
It's a normal call when you call a person and hear the usual number of rings before getting voicemail. But if the person has blocked you, here's the big indicator. You only hear a single ring before being diverted to voicemail.
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.
To check if you're blocked, try calling the person you suspect has blocked you. If the call goes straight to voicemail every time, it's possible that you've been blocked.
If the chat bubble is green, that could indicate someone has blocked you, especially if your chats with this person used to be blue. However, this is only true if both of you use iMessage on iPhones. If the other person switched to an Android phone, their bubble may have turned green (plus, they may have a new number).
When you block a phone number or contact, they can still leave a voicemail, but you won't get a notification. Messages that are sent or received won't be delivered. Also, the contact won't get a notification that the call or message was blocked. When you block an email address from Mail, it goes to the trash folder.
Sometimes, people may block you because they need a break from social media. The constant barrage of information and notifications can be overwhelming, and some people may find that they need to step back from their online presence in order to focus on other aspects of their life.
The psychology of blocking someone can have a harsh impact, with some individuals brushing it off while others become deeply aggrieved. This can lead to negative emotional reactions, ranging from sadness to anger and even depression. In extreme cases, it can cause a person to seek out and confront the blocker.
When you call a number that has blocked yours, you may hear one or half a ring or no rings at all and then the call will go to voicemail. If it goes straight to voicemail, their phone may also be off or out of range, or they may have temporarily turned on Do Not Disturb mode to work, drive, or sleep.
Use a public phone.
Perhaps the simplest solution is to call this person using a number that they have not blocked. This way, they won't expect that it's you on the other end of the line. If they hang up, they hang up – but you should at least get through the call-block screening.
Send A Text Message:
If someone has blocked your number on Android, your SMS will not be delivered to the other person. However, you will not know whether the message has been delivered to the person.
When someone tries to text a blocked number on an Android device, the message will not be delivered. The sender will likely receive a notification that the message was not delivered, but they won't know that the number is actually blocked.
The recipient opted out of messages or blocked your number
Similarly, if a recipient blocks your phone number, your message won't be delivered. This is the likely explanation if you don't see a “Delivered” or “Read” message notification.
If your iPhone messages are green, it means they're being sent as SMS texts rather than iMessages. You'll always see green when texting Android users, or when you're not connected to the internet.
First things first: people are not notified when you block them. As soon as you block someone on iPhone, they lose the ability to text or call you. Except the blocking happens at the level of your device.
When you're blocked on iMessage, Apple's messaging service prevents your instant messages from getting delivered to the person you're trying to reach. If you have text message fallback enabled, your device will resort to sending the message as a text, meaning the bubble will turn green after someone blocks you.
