How does imessage know that someone else blocked it?

Whether iMessage is blocked or not can be determined by looking at the color and sending status of the text bubble.

There is a difference between iMessage and SMS/MMS on iOS devices. When two iPhone users send messages to each other using Wi-Fi or mobile data, their text bubbles are blue, which means they are using iMessage service.

If your text bubble is blue and turns green one day, the person you are talking to may not have an Internet connection, or may have switched to an Android device. However, if the color of the text bubbles changes, and they take some time to reply, it may indicate that they have stopped you.

The iMessage you sent had the status of sent or read before, but now it is gone. This may mean that the person who sent the message has blocked you on iMessage, or the "Send read receipt" option has been turned off.

Skills of using imessage

If you send pictures or voices to friends who don't have iMessage, they will send them by MMS. To avoid this embarrassing situation, we must distinguish between green SMS and MMS or blue iMessage.

The comment function has been added to the current message. After long press the message, a selection box will pop up. We can praise the message or express surprise, like, question and laugh. After sending, these comments will be displayed directly in the upper right corner of the message, which can be seen by both parties.

IMessage also adds a sticker function, which we can understand as an emoticon package of WeChat, but it is somewhat different from the emoticon package. In addition to sending the sticker directly, we can also drag the sticker to any position in the dialog box to paste it.
