Line Scheduled Message? How It Works in Chat Apps

Line scheduled messages let you write a message now and have Line deliver it automatically at a chosen time. You set the date and time, and Line sends the message to the selected chat even if you are offline. This guide explains how to use the feature on iPhone, Android, and desktop, what limits apply, and how it compares to other apps.

What Is a Scheduled Message on Line?

Scheduled messaging is a built-in feature in the Line app that lets you compose a message and delay its delivery. When you schedule a message, the app stores it locally on your device and sends it at the exact time you set. The message appears in the chat as if you had typed it at that moment, with your name and profile picture. The feature works for both individual and group chats, and you can schedule text, images, stickers, and files.

Line introduced this feature in 2021 for iOS and Android, and later added it to the desktop app. It is available in the free version of Line, so you do not need a paid subscription. The main advantage is convenience: you can prepare a birthday greeting the night before, remind a colleague about a meeting while you are busy, or send a message during a time zone difference without staying awake.

How to Schedule a Message on Line (Step by Step)

The process is almost identical on iPhone, Android, and desktop, with only minor differences in menu placement. Here are the steps for the mobile app:

Open the chat where you want to send the scheduled message.
Type your message in the text field as you normally would.
Instead of tapping the send button, press and hold the send button (the paper plane icon).
A menu appears with options like “Schedule” and “Send later.” Tap “Schedule.”
Choose the date and time using the picker. You can also select a preset like “Tomorrow morning.”
Tap “Schedule” or “OK” to confirm. The message is now queued.

On the desktop app, the process is the same: type your message, then right-click the send button (or click the small arrow next to it) and choose “Schedule.” If you do not see the option, make sure your Line app is updated to the latest version.

Managing and Editing Scheduled Messages

After you schedule a message, you can view, edit, or cancel it before it sends. Here is how:

View all scheduled messages: Go to the chat, tap the clock icon in the text field (or the “Scheduled” tab in the chat menu). You will see a list of pending messages.
Edit a scheduled message: Tap the message, change the text or time, and save. The changes apply immediately.
Cancel a scheduled message: Tap the message and select “Delete” or “Cancel.” The message will not be sent.
Reschedule: You can change the date and time as many times as you want before delivery.

Once the message is sent, it cannot be edited or retracted. It behaves like any other sent message, so you cannot unsend it after delivery.

Limitations and Common Problems

Scheduled messages have a few important limitations that users often run into:

Device must be on: The message is sent from your device, not from Line’s servers. If your phone is off, has no internet, or the app is force-closed, the message will not send at the scheduled time. It will send as soon as the device reconnects.
Time zone: The schedule uses your device’s local time zone. If you travel or change time zones, the message will send at the new local time, which may be different from what you intended.
Maximum messages: There is no official limit on the number of scheduled messages, but very large numbers may cause performance issues on older devices.
Group chats: You can schedule messages in groups, but if you are removed from the group before the scheduled time, the message will not send.
No recurring schedules: You cannot set a message to repeat daily or weekly. Each message must be scheduled individually.

If a scheduled message does not send, check your internet connection, restart the app, and confirm the device was not in airplane mode at the scheduled time.

How It Compares to Other Apps

Line is not the only app with scheduled messaging, but its implementation has some differences:

Telegram: Telegram has a built-in scheduler that works from any device, even if the sending device is offline, because it runs on Telegram’s servers. Line’s version requires the device to be on.
WhatsApp: WhatsApp does not have a native scheduled message feature. Users rely on third-party apps or reminders, which are less reliable.
Slack: Slack lets you schedule messages in channels and DMs, with the ability to pick from preset times or a custom date. It also works server-side.
Email apps: Most email clients (Gmail, Outlook) have scheduled send, but that is for email, not chat.

Line’s approach is simpler than Telegram’s but has the device-on requirement. For most casual use, this is not a problem, but if you need guaranteed delivery while your phone is off, consider using Telegram or a server-based service.

Frequently Asked Questions

Can I schedule a message on Line without holding the send button?

On some versions, you can tap the “+” icon next to the text field and select “Schedule.” If you do not see it, long-press the send button is the universal method.

Will the scheduled message send if I close the app?

No. The message is stored on your device, so the app must be running in the background (or at least the device must be on). If you force-close the app, the message will not send until you reopen it.

Can I schedule a message for someone who is not my friend?

No. You can only schedule messages in chats with people you have already started. You cannot schedule a message to a new contact without first sending a normal message.

Is there a limit to how far in advance I can schedule?

Line allows scheduling up to 30 days in advance. After that, you will get an error.

What happens if I delete the chat after scheduling?

Deleting the chat also deletes any scheduled messages in it. The message will not be sent.

Can I schedule a message in a group chat if I am an admin?

Yes, any member can schedule a message in a group chat, not just admins. The message will send as normal, but if you are removed before the time, it will not send.

Final Tips

Use scheduled messages for time-sensitive greetings, reminders, or to avoid disturbing someone at odd hours. Always double-check the time zone and ensure your device is charged and connected. If you rely on scheduled messages for work, consider testing the feature in a private chat first to understand how it behaves on your device.
