I accidentally sent a message on LINE! I tried to "cancel sending" right away, but I couldn't find the button... Have you ever had such an experience?
Actually, in the November 2025 update, the time you can cancel a LINE send has been shortened from 24 hours to 1 hour. The number of cases in which people used to think, ``I'll just delete it later,'' but now it's no longer possible to cancel it, is rapidly increasing.
In this article, based on the latest specifications as of March 2026, we will explain why you are unable to cancel a LINE send and what to do if you are unable to cancel. We will also touch on the "cancellation without notice" feature, which is exclusive to LYP Premium members, so please refer to it.
How LINE send cancellation was shortened from 24 hours to 1 hour
On November 7, 2025, the time limit for LINE's send cancellation function changed significantly. Previously, you could cancel your request within 24 hours of sending it, but after the update you can now cancel your request within 1 hour of sending it.
According to LINE Yahoo, most users who used the undo send function completed the operation within one hour, and the specifications were changed based on this actual usage situation. In other words, the judgment is that 1 hour is enough.
However, the current situation is that many people do not know about this change and think that it is okay within 24 hours. On X, I often see posts saying, "I can't cancel the LINE send!"
6 reasons why you can't cancel sending
If the "Cancel Send" button does not appear, or if you cannot cancel by tapping it, the following may be the cause:
1. More than an hour has passed since the message was sent
From November 2025, free users can only unsend within one hour of sending. After one hour, the "Cancel sending" menu will no longer be displayed and "Delete" will be the only option left.
2. I pressed "Delete" instead of "Cancel Send"
LINE has two functions: "Undo sending" and "Deleting", but if you don't know the difference between them, you'll be in trouble.
- Unsend: The message disappears from both your and the other party's chat screens
- Delete: Disappears only from your chat screen (remains visible to the other party)
If you select "Delete", the message will remain displayed on the other party's screen. Moreover, once you execute "Delete", the message disappears from your screen, so you cannot switch to "Undo Send" from there.
3. The version of the LINE app is old
The send cancellation function is supported in LINE version 7.12.0 or later. If the other party's LINE version is an older version, the cancellation may not be reflected correctly. You can also download your own apps from App Store or Google Please update to the latest version with Play.
4. Unstable communication environment
Send cancellation operation requires communication with the server. Cancellation may not be completed in areas where the signal is weak or Wi-Fi is unstable. Please try again in a stable communication environment.
5. There is no partner in the talk room (withdrawal/block)
If the other party has deleted their LINE account or blocked you, the cancellation process may not be reflected correctly. However, it will be displayed as canceled from your chat screen.
6. Temporary server failure
If there is a problem on the LINE server side, undo sending may not work. Check out the trouble information on LINE Official X (Twitter).
The correct way to cancel sending (latest 2026)
Please check the operating procedure again. The basics are the same for both iPhone and Android.
- Press and hold the message you want to cancel
- Tap “Cancel Send” from the menu that appears
- Tap “Cancel Send” again on the confirmation screen
The message will now disappear from both your and the other party's chat screens. However, the message ``○○ canceled sending the message'' will remain on the other party's chat screen. In other words, the other party will know that you canceled something.
Also, if a push notification was displayed on the other party's smartphone before you canceled it, the beginning of the message may remain in the notification field. Remember that unsend is not a panacea.
LYP Premium membership can be canceled within 7 days and without notice
At the same time as the November 2025 update, the unsend function has been significantly enhanced for members of LYP Premium (508 yen per month, tax included).
LYP Premium exclusive benefits
- Cancellation period extended to 7 days: 1 hour for free users can be canceled for up to 7 days (168 hours)
- "Cancel sending without notification" function: Can be canceled without leaving message "Unsent" message only if the recipient has not read the message
However, there are some caveats. "Cancel sending without notification" can be used only when the recipient has not read the message. If the message is marked as read, even if you are a LYP Premium member, the message "○○ canceled sending the message" will remain.
LYP Premium has other benefits such as point redemption for Yahoo! Shopping and unlimited storage for Yahoo! Easy Backup, so it may be worth considering if you are a heavy LINE user.
4 things to do if you can't cancel
An hour has passed or you pressed "Delete"... Here's what you can do if you can't undo it anymore.
Solution 1: Try canceling the send from another device
Even if you press "Delete" on your smartphone, if you log in to another device such as PC version of LINE or iPad version of LINE, the message may still be there. If you can "cancel sending" from another device, you can also delete it from the other party's chat screen. However, you must operate within 1 hour (within 7 days for LYP Premium).
Countermeasure 2: Immediately send an apology/correction message
If you can't cancel in time, it's best to follow up honestly rather than trying to mislead.
- "Sorry, the previous message was incorrect!"
- "I sent it to the wrong address, please ignore it!"
- “Correction. The correct name is ○○”
It will leave a better impression on the other person if you immediately follow up with something rather than saying nothing in a hurry.
Solution 3: Do not delete the chat room
Some people panic and delete the entire chat room, but this is no good. Deleting a chat room has no effect on the other party's chat screen. Your chat history will simply disappear, but the problem will not be resolved.
Solution 4: Configure settings to prevent future erroneous sending
Please review your LINE settings to avoid repeating the same mistake.
- Turn off “Enter to Send”: Settings → Talk → Turn off “Enter to Send”. You can prevent the accident of sending when trying to break a line
- Get in the habit of checking the chat room name: If you are someone who tends to make mistakes when sending messages, it is a good idea to change your friend's display name to make it easier to understand
- Take a deep breath before sending important messages: The more emotional the message, the better to take a deep breath before sending it
Difference chart between "Undo Send" and "Delete"
| Item | Cancel sending | Delete |
|---|---|---|
| The other party's chat screen | Message disappears | Message remains |
| Notify the other party | Display "Cancelled" | None (the other party will not notice) |
| Time limit (free) | Within 1 hour from sending | Anytime possible |
| Time limit (LYP Premium) | Within 7 days from submission | Anytime possible |
| What can be undone | Text, images, stamps, etc. | Only your screen |
Roughly speaking, it is OK as long as you remember that "Undo send" will erase the message from the other party, and "Delete" will erase it only from you. If you make a mistake in these two things, you can't take it back, so be sure to check before operating.
FAQ
If I cancel sending, will the other person find out?
Yes, I will find out. If you are a free user, "○○ canceled sending your message" will be displayed on the other party's chat screen. Only if you are a LYP Premium member and the recipient has not read it, you can cancel without leaving this message.
Is it absolutely impossible to cancel after 1 hour?
If you are a free user, you cannot cancel the send after 1 hour. If you subscribe to LYP Premium (508 yen per month), you will be able to cancel messages within 7 days of sending. However, it does not apply to messages sent before joining.
Will the content of the push notification be revealed even if I cancel sending?
Yes. Push notifications displayed on the lock screen or status bar of the other person's smartphone will not disappear even if you cancel sending them. Keep in mind that undoing is not a "complete deletion" feature, as the beginning of the message may remain in the notification.
Can I cancel sending in a group chat?
Yes, you can. Messages in group chats can also be canceled using the same operations as in one-on-one conversations. The message will disappear from the chat screen of everyone in the group, but everyone will see the message ``Unsent.''
Can I also cancel sending stamps and images?
Yes, it is possible to cancel sending not only text messages, but also almost all types of sending such as stamps, images, videos, files, location information, and contact information. You can cancel it by operating within the time limit.
