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.
“The last message that you know was received and responded to…should have a 'delivered' status,” Lavelle explains. If, under the messages you've sent after that, you don't see that “delivered” notification, that could mean that person has blocked you.
Why do some text messages say delivered and some do not Android? There can be a few reasons why some text messages say "delivered" and some do not on Android. The primary cause is that the recipient's phone may not be connected to their cellular or Wi-Fi network, so the message cannot be delivered.
Actually, iMessage not saying “Delivered” simply means the messages have not yet been successfully delivered to the recipient's device due to some reasons. Reasons could be: WiFi not working on iPhone/iPad or the iDevice don't have cellular data networks, they have their iPhone off or on Do Not Disturb mode, etc.
If the iMessage never shows a “Delivered” or “Read” message, and it's still blue, then you may have been blocked – but not always. If the iMessage goes through and shows a “Read” receipt, then you have definitely not been blocked.
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).
If you see a green message bubble instead of a blue one, then that message was sent using MMS/SMS instead of iMessage. There are several reasons for this: The person that you sent the message to doesn't have an Apple device. iMessage is turned off on your device or on your recipient's device.
The sender will likely receive a notification that the message was not delivered, but they won't know that the number is actually blocked.
Send them an SMS message
When you send them an SMS and you get the "Delivered" notification underneath it, you weren't blocked. If you get a notification like "Message Not Delivered" or you get no notification at all, that's a sign of a potential block.
when your text message does not say delivered it means that the text itself was sent but it did not reach the other persons phone yet. That may be because the other person does not have cellular connection, they may have a dead phone or if youre using an app such as messenger then they have deleted the app.
A single gray checkmark indicates a successfully sent message. The appearance of a second gray checkmark shows your message was delivered to the recipient's phone. The two checkmarks will turn blue if the recipient has viewed your message.
Look for “Delivered” under your last message.
It will appear just below the message bubble. If your message does not say “Delivered”, check the top of your screen to see if it says “Sending…” or “Sending 1 of X”. If you see nothing listed under your last message, your message has not yet been delivered.
If you send a message as a regular SMS in the green text bubble and you do not get a “Delivered” notification but instead get a notification similar to “Message not Delivered” or no message at all, that means you were probably blocked.
Android users may determine if someone has blocked their number by checking notifications. If the “sent” icon changes to “delivered,” the receiver is likely not blocked you. On the other hand, if it stays on “sent,” there's a good chance they have blocked your 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.
Check the chat bubble color
The delivery status appears underneath the bubble when you enable Read Receipts in the iMessage settings menu. If the chat bubble is green, that could indicate someone has blocked you, especially if your chats with this person used to be blue.
Blocking a number on an iPhone is straightforward but what exactly happens when you do it? Once blocked, the person at the other end cannot reach you via text or call and their messages won't even appear in your notifications or voicemail.
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.
A green text message on your iPhone isn't a sign that your phone number was blocked, or that the text was not delivered. Instead, it means that the message was sent as a standard SMS message rather than an iMessage, which will appear as blue.
Green texts, on the other hand, move text around the world over a basic cellular signal, like a flip phone of yore. What this means is that if you've exceeded your phone plan's data limit, or you're out of range of LTE or Wi-Fi, iMessage won't work. Your phone will likely resend the text as a green bubble SMS.
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.
Another way to know if someone blocked you on iMessage is to check the bubble color. If you see green bubbles, this means that your text messages are being sent through SMS, and they might have blocked you on iMessage.
If it's green, it's an ordinary text message and doesn't offer the read/delivered receipts. iMessage only works when you're sending messages to other iPhone users using the Messages app.
