Checking a chat message's sent status:
If there is an issue with a chat message that you sent, one of the following icons will appear. (Messages that were sent successfully will have no icon or the read mark next to them.)

This icon may appear if your smartphone's network connection is unstable. Try sending your message in an area with a strong network connection.

If your message couldn't be sent due to a network error, a button to resend it will appear. After letting some time pass, try sending the message again by tapping
> Resend.

About Read receipts
When a friend sees a message you sent them on LINE, Read will appear to the left of that message. In group chats, numbers displayed next to Read (e.g. Read 2) indicate the number of people who have seen your message.
Depending on the recipient's device, a message may be marked as Read when they receive a notification for it. As such, the Read receipt doesn't necessarily mean that your chat message has been seen. Also, the time that appears next to Read is the time you sent the message, not the time someone checked it.
Please use Read receipts as an approximate guide to whether or not your messages have been seen.
