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.
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.
When someone you've blocked tries to text you, you will not receive text messages from them. The blocked person also does not receive any notification that they're blocked.
If someone has blocked you, you will only see one grey tick, indicating that the message was sent but not delivered.
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.
A green bubble could also indicate that someone blocked you, especially when the bubbles have always been blue. When blocking occurs, iMessage sends your text, but the recipient never receives it. Your old messages remain blue, but the latest texts you send after they've blocked you turn green.
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.
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.
When someone switches to a new device that doesn't run on iOS, they may leave their phone number in the app. In that case, you may not get the “Delivered” tag if you message them, but the message bubbles will be blue.
If you see a green message bubble
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.
If you send a message to someone and the message is not delivered, meaning that only an unfilled check mark icon appears, it generally means one of two things: The user has not logged into Facebook. The user has blocked you on Messenger.
No, it doesn't mean that the text won't go through or hasn't gone through. Instead, a green text message on an iPhone is an SMS message that has been delivered to a phone that is not an iPhone or Apple device (ie. an Android).
Why are my texts green? 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.
For green messages, the texts that are sent are compatible with a wider range of phones and receiving services than blue iMessage texts. Since Android and other carriers operate within the SMS and MMS standards of text communication, these green texts are more versatile in who they can reach with their texts.
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.
If the call ends after one ring (or, in some cases, half of a ring) and you are diverted to voicemail, you are either blocked or your contact's phone is dead. If the phone immediately hangs up or beeps rapidly, then either the line is busy or the contact blocked you through their carrier.
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 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.
