[Reporter Qiu Qiaozhen/Reported from Taipei] LINE's "appointment message" function has made new progress. According to information from Taiwan's LINE official support center, LINE Labs has included "appointment message" in the function list and disclosed detailed operation methods and usage restrictions. However, the official also reminded that this function is still being gradually opened and is not yet fully available to all users.
At the "LINE CONVERGE 2026" annual press conference held in October this year, LINE announced that it would launch six advanced features for LINE Premium members from the fourth quarter of 2026 to the first half of 2027, including editing messages, silent messages, call recording, scheduled messages, incognito preview, and marking as read later. Among them, "Schedule Message" allows users to set the transmission time in advance, and the system will automatically send messages at the designated time. It is suitable for situations such as birthday wishes, work reminders, and cross-time zone communication.
Now, LINE's official support center has disclosed the detailed usage rules of "Reservation Messages", including the earliest it can be scheduled for 5 minutes to be sent, the latest can be set to 1 year later, each account can be scheduled for up to 500 messages, etc. Users must use the main device with the latest version of LINE installed.
Scope and limitations of use
According to the instructions provided by LINE's official support center, "Reservation messages" can be used in 1-on-1 chat rooms, multi-person chat rooms, group chat rooms and Keep notes. Currently, only text messages are supported, and the maximum number of words in each reservation message is 10,000 words. The earliest reservation time is 5 minutes from the current operation (for example, 8:00 now, the fastest can be set is 8:05), and the maximum reservation time can be 1 year later, and can be set in 1-minute increments. Each account can reserve up to 500 messages.
You can also manage it after making a reservation
In addition, before the reservation message is officially sent, you can still modify the content, change the transmission date and time, and choose to send or delete it immediately. Users can also set a resend time for sent or received messages as a reminder. Messages sent through the reservation function are displayed in the same way as ordinary messages. The recipient will not receive special notifications sent using the reservation function.
How to enable and set up
As for how to turn on this feature? Users can first update LINE to the latest version, then go to LINE's "Home Page", click "Settings" in the upper right corner, and then select "LINE Labs" to turn on the "Reservation Message" function.
【Operating steps】
How to use the "Reservation Message" function? According to LINE's official support center, users can enter text in the message input field at the bottom of the chat room, then long-press the "Send" icon, click "Schedule Send", then set the time they want to send, and finally click "Schedule Message" to complete the setting. In addition, users can also set up scheduled transmission by selecting "Schedule Message" through the "+" menu at the bottom of the chat room.
LINE officials also remind that if the user closes the "Reservation Message" page before completing the reservation settings, the entered content will be deleted and will not be automatically saved as a draft; if the other party has deleted their LINE account, they will not be able to schedule a message. It is important to note that if there are still reservation messages waiting to be sent but the "Reservation Message" function is turned off in LINE Labs, the originally set reservation messages will also be deleted.
In addition, if the time zone between the time of reservation and the time of actual transmission is different, the system will use the current time zone of the reservation as the basis; if a new member joins the group after setting the reservation message in the group chat room, the new member may not receive the message sent by reservation. Officials recommend restarting the LINE application after the new member joins.
