Schedule Message iPhone: How to Use Send Later in iOS 18

Yes you can schedule message iPhone with the Send Later feature in Messages, available on iOS 18 and later.

It works with iMessage, lets you pick a future time, and sends automatically even if your phone is off.

Requirements Before You Start

Before you try to schedule a message on iPhone, it helps to know what the feature actually needs. It's not available everywhere, and it doesn't work with every kind of conversation.

iOS Version Needed to Schedule Message iPhone

Send Later requires iOS 18 or newer. According to TechCrunch, message scheduling was introduced as part of the iOS 18 update alongside RCS support, after years of users relying on workarounds to achieve the same result.

If you're on an earlier version, you won't see the option at all no error message, it just won't appear in the menu.

Checking your software version first saves you the confusion of hunting for a button that isn't there.

iMessage Must Be Turned On

This feature only works inside iMessage conversations. If iMessage is switched off in your settings, or the conversation is a regular SMS thread, scheduling won't be an option for that chat.

What Happens With Non-iMessage Contacts

If you're texting someone who doesn't use iMessage an Android user, for instance that conversation shows up as SMS, and Send Later simply isn't available for it.

In practice, this is the most common reason people can't find the scheduling option: they're trying to use it in a green-bubble chat.

How to Schedule Message iPhone (Step-by-Step)

Once the requirements above are met, the process itself is short.

Step 1: Open Messages and Pick a Conversation

Open an existing thread, or start a new one, as long as it's with an iMessage contact.

Step 2: Tap "+" and Select Send Later

Next to the text field, tap the plus icon, then choose Send Later from the menu that pops up.

Step 3: Choose the Date and Time

Tap the time field to open the scheduler and pick when you want the message sent. You can schedule up to 14 days ahead.

Step 4: Type Your Message and Confirm

Write your message as normal, then tap the send arrow. That's it it's queued.

How You Know a Message Is Scheduled

The message bubble shows a dashed border instead of a solid one, and the scheduled time appears at the top of the conversation.

Once it's actually sent, that dashed line disappears and the bubble looks like any other message.

What Happens After You Schedule It

A scheduled message doesn't just sit passively on your phone a few things happen behind the scenes worth understanding.

Delivery When Your iPhone Is Offline

The message will still send at the scheduled time even if your iPhone is powered off or has no signal. Apple holds it and pushes it out from its servers, not from your device directly.

Whether the Recipient Can Tell

The recipient has no way of knowing a message was scheduled. It arrives looking like any other text, with no label or indicator on their end.

How Long Apple Stores Scheduled Messages

While waiting to be sent, the message is encrypted and stored temporarily on Apple's servers.

This lines up with how iMessage generally handles data according to Wikipedia, iMessage uses end-to-end encryption so that only the sender and recipient can read a message's contents.

Once it's delivered, the scheduled copy is removed from those servers — it isn't kept there indefinitely.

Changing a Scheduled Message

Plans change, and Apple built in a way to adjust a message after it's queued, right up until the moment it's due to send.

How to Reschedule It

Open the conversation, tap Edit next to the scheduled date, then Edit Time to pick a new one.

How to Edit the Text

Touch and hold the scheduled message bubble, tap Edit, make your changes, and confirm.

How to Cancel It

Touch and hold the message, then tap Delete. This cancels it outright it won't be sent.

Limits Worth Knowing

A few practical limits are easy to miss until you run into them.

14-Day Maximum

You can't schedule a message more than two weeks out. For anything further ahead, you'd need a different approach, like a calendar reminder.

You Need to Be Online to Make Changes

Editing, rescheduling, or canceling requires an internet connection. If you're offline when you try to make a change, it won't go through until you're back online worth remembering if you're trying to cancel something last minute.

Group Messages

Send Later is generally used in one-to-one conversations. In group threads, behavior can be less consistent, so it's worth double-checking the scheduled indicator appears before assuming it's set.

If You're on an Older iPhone (iOS 13–17)

If your iPhone can't run iOS 18, native scheduling isn't an option. Most people in this situation turn to the Shortcuts app instead, which has supported message automation for years.

Using Shortcuts as a Workaround

This isn't true scheduling in the same sense it's an automation that triggers a message send at a set time.

Setting Up the Automation

Open Shortcuts, go to the Automation tab, and create a new personal automation using "Time of Day" as the trigger.

Adding the Send Message Action

Add the Send Message action, type your text, and choose the recipient. Review the details before saving.

Deleting It After a One-Time Send

If it's a one-off message, delete the automation afterward. Otherwise it will keep repeating on the same schedule, which usually isn't what people actually want.

FAQs

Do I need iMessage to schedule a message on iPhone?

Yes. Send Later only works within iMessage conversations it isn't available for standard SMS or MMS threads.

Will the recipient know my message was scheduled?

No. The message arrives looking exactly like any other text, with no visible indication it was set up in advance.

Can I schedule a message to someone on Android?

Not with the native feature. That conversation runs over SMS, not iMessage, so Send Later won't appear as an option.

What happens if my iPhone is off at the scheduled time?

It still sends. Apple holds the message on its servers and delivers it at the set time, regardless of your device's power state.

Can I schedule a message further than 14 days ahead?

Not with Send Later. For anything beyond that window, a calendar reminder or the Shortcuts automation is the more practical route.
