Will WhatsApp Messages Send or Deliver If the Phone Is Off?

It depends on whose phone is off. If the recipient's phone is off, your message is sent and shows one gray check. It is delivered, and gets a second check, once their phone or one of their linked devices is back online. If your phone is off, WhatsApp keeps working on your linked devices. You can still send from WhatsApp Web or the desktop app on a computer that is on, and a cloud scheduler such as Chatmaid Schedule sends at a set time with none of your devices switched on. Scheduler apps that run on the phone itself stop when it powers down.

WhatsApp's own scheduler, as of October 2026: WhatsApp has started testing scheduled messages with some beta testers, on Android since October 12 and on iPhone through TestFlight since October 22 (WABetaInfo: Android, iPhone). It is not in the regular app on either phone, and there is no release date. Testers can schedule from 10 minutes to two weeks ahead, with one photo or video per message and no repeat option, and the message goes out even if their phone is offline. If you don't have the beta, need a later date or want a message to repeat, a cloud scheduler such as Chatmaid sends on time with your phone off. Full status: Can you schedule messages on WhatsApp?

Will your message be delivered if their phone is off?

Your message still leaves your phone and shows one gray check. It just can't be delivered until their phone or one of their linked devices is online. WhatsApp's privacy policy says an undelivered message is kept in encrypted form on its servers for up to 30 days while it tries to deliver it, and deleted after that.

WhatsApp's help center page on read receipts explains the check marks:

• One gray check: the message was sent.
• Two gray checks: it was delivered to the recipient's phone or one of their linked devices.
• Two blue checks: the recipient read it.

The same page says that if the recipient's phone is off and the message is not delivered to any of their linked devices, the second check mark won't appear.

One gray check on its own doesn't prove their phone is off. Their phone may be on but without a connection, and WhatsApp's help center says messages to someone who has blocked you only ever show one gray check (Being blocked by someone). In a group, the second check appears only once every member has received the message.

Why phone-based schedulers fail when your phone is off

Scheduler apps on your phone send from that phone. On Android, apps such as SKEDit, Wasavi and Auto Text press send for you, typically through Android's accessibility service, and SKEDit's own site says the phone has to be on and online at the send time. On iPhone, an Apple Shortcuts automation opens a wa.me link. The automation runs on the iPhone, so it has to be on at send time, and in many setups unlocked so you can confirm the send.

The weak point is the same in each of these setups. At the scheduled time, something on your phone has to wake up and press send. If the phone is off, the battery is dead or there is no signal, nothing is running, and the message does not go out at that time.

A message you send by hand from your phone has the same weak point. If your phone dies while the message still shows a clock, it has not been sent yet. WhatsApp's help center says a clock means the message is not yet sent or delivered.

Browser extensions such as Blueticks are different. They run in WhatsApp Web, which is a linked device, so they keep sending with your phone off as long as the computer is on with WhatsApp Web open in Chrome. That is how Blueticks works on its Basic and Standard plans; its Pro plan sends from its cloud, so it keeps going with the computer off.

Which methods send while your phone is off?

We make Chatmaid Schedule. The other rows come from WhatsApp's help center, WABetaInfo and each tool's own site or help pages, as of October 2026.

For a closer look at each app, including price and how far ahead it schedules, see our comparison of WhatsApp scheduling apps.

What WhatsApp linked devices do while your phone is off

Linked devices are what make sending without your phone possible. WhatsApp's help center page About linked devices explains how they work:

• You can link up to four devices at a time to your primary phone. You still need the primary phone to register your account and to link a new device.
• Linked devices include WhatsApp Web, the Windows and Mac apps, and tablets.
• Linked devices work without your phone online, and WhatsApp lists using WhatsApp on your computer "even when your phone is off" as a benefit. They log out if your phone is unused for over 14 days.

In practice, with your phone off you can still open WhatsApp Web or the desktop app and send right away, as long as that computer is on and online. To send at a set time while all your devices are off, the linked device has to run somewhere that stays on. That is what a cloud scheduler does.

How Chatmaid sends WhatsApp messages from the cloud

Chatmaid Schedule links to your WhatsApp the way WhatsApp Web does. It becomes one of the linked devices on your account, and that connection is held by Chatmaid's cloud, not by your phone. It is not the WhatsApp Business API, and nothing is spoofed. Chatmaid uses one of the four linked-device slots, so if four devices are already linked, unlink one before you connect.

Here is what happens when you schedule a message:

1. When you confirm, the message, the recipients and the send time are saved to Chatmaid's cloud.
2. At the scheduled time, the cloud sends the message through your linked connection.
3. The message arrives from your own WhatsApp number, in your normal chat with that person or group.

Between steps 1 and 3, your phone can be off, out of battery or offline. Afterwards, Message History shows your messages under Scheduled, Recurring and Completed. A send that failed is marked Failed under Completed. You can open a scheduled message and edit it before it goes out.

How to schedule a WhatsApp message that sends while your phone is off

1. Install Chatmaid Schedule from the App Store or Google Play, or start in a browser, and sign up with the phone number your WhatsApp uses, including the country code. The link code in step 2 is for that number. The 7-day free trial includes every feature and does not ask for a card (pricing).
2. Connect your WhatsApp once, with your phone on. In Chatmaid, tap Connect with code. Then, in WhatsApp on your phone, open Linked devices (under Settings on iPhone, or the three-dot menu on Android), tap Link a device, choose Link with phone number instead and enter the code Chatmaid shows you. If you have a computer nearby, the app also gives you a page to open in your browser so you can scan a QR code instead.
3. Choose recipients. Pick phone contacts, WhatsApp groups, or a number you have not saved from the Unsaved tab.
4. Write the message. Add photos, videos, documents or a voice note if you need them. Bold, italic and strikethrough are available in the composer.
5. Pick the timing. Choose One-time or Recurring (daily, weekly or monthly), then set the date and time. There is no two-week cap on how far ahead you can schedule.
6. Confirm. On the confirm screen, check that the connection status says Phone connected, then tap Confirm Schedule.

The message now lives in the cloud. You can turn your phone off. For a walkthrough with more detail for your platform, see the iPhone guide or the Android guide.

Practical scenarios: travel, battery and time zones

An overnight flight

Say you fly overnight and promised a client a follow-up at 9:00 a.m. Schedule it before you board, check that it shows under Scheduled in Message History, then switch to airplane mode. The message goes out on time while you are in the air.

Do this while you still have signal, because the cloud can only send what has reached it. If you write the message after you lose signal, Chatmaid saves it on your phone and uploads it the next time you open the app online. If the send time passes first, it is not sent. More in how to schedule WhatsApp messages without internet.

A long trip with your home phone switched off

Some people travel with a local SIM in a second phone and leave their usual phone off in a drawer. Your scheduled messages keep going out from your usual WhatsApp number, because Chatmaid's connection does not depend on that phone being on.

Replies come to your usual number. To read them on the trip, keep WhatsApp Web or the desktop app linked on a laptop, which works with the phone off.

The 14-day rule still applies. If the trip is longer than two weeks, plan to turn the phone on and open WhatsApp before two weeks pass, so your linked devices, Chatmaid included, stay logged in.

A battery that won't last the day

If you know it will be a long day, schedule the messages that matter in the morning: a 5:00 p.m. reminder to a customer, a 7:00 p.m. check-in with family. If the battery dies at lunch, both still go out.

Recurring messages work the same way, so a weekly Monday reminder does not depend on your phone being charged every Monday. Our guide to recurring WhatsApp messages shows how to set those up.

Time zones

You pick the time on your own clock, so convert first. If you are in Los Angeles and your client is in New York, they are three hours ahead: 9:00 a.m. for them is 6:00 a.m. for you. Schedule the message for 6:00 a.m. and sleep through it.

A one-time message is saved as a fixed moment. If you schedule it and then fly to another time zone, it still goes out at that same moment, not at 6:00 a.m. in your new location.

Limits to know before you rely on it

• Open WhatsApp on your phone at least every two weeks. WhatsApp logs out linked devices when your phone is unused for over 14 days, and Chatmaid connects as a linked device.
• Keep Chatmaid in your linked devices. If you remove it from Linked devices in WhatsApp, or disconnect it in the app, scheduled messages cannot go out until you connect again; any that failed show as Failed under Completed in Message History.
• Make sure the schedule reached the cloud. A message that only exists on your phone, because you created it offline and never synced, is not sent.
• Know WhatsApp's position on third-party apps. WhatsApp's linked devices page says to link only its own apps, and warns that linking an unofficial app or website may result in a temporary or permanent account ban. With normal use, restrictions are very unlikely. They are typically triggered when an account behaves like spam, such as unsolicited bulk messages to people who do not have you saved. Only message people who expect to hear from you.

Frequently asked questions

Can a WhatsApp message be delivered if the phone is off?

It depends on whose phone. If the recipient's phone is off, the message is sent and shows one gray check. It is delivered, with two checks, once their phone or one of their linked devices is online. If yours is off, a message scheduled with a cloud service like Chatmaid is still sent, because a linked device in the cloud sends it.

Why does my WhatsApp message only show one gray check?

It was sent but not delivered yet. Usually their phone is off or offline and none of their linked devices is online. It gets a second check once one of them is, and WhatsApp keeps trying for up to 30 days. Messages to someone who has blocked you also stay on one gray check.

Can I send WhatsApp messages with my phone off on iPhone?

Yes. WhatsApp Web, the Mac and Windows apps and an iPad keep working while your iPhone is off. To send at a set time with the iPhone off and no computer left running, you need a cloud scheduler such as Chatmaid Schedule. As of October 2026, WhatsApp's own scheduled messages have only started reaching some iPhone beta testers through TestFlight. They are not in the regular App Store version and cannot be scheduled more than two weeks ahead.

Can I use WhatsApp Web when my phone is off?

Yes. WhatsApp Web, the desktop apps and tablets are linked devices, and WhatsApp's help center says they work without your phone online. The computer itself has to be on and connected.

How long can my phone stay off before scheduled messages stop?

WhatsApp logs out linked devices if your phone is unused for over 14 days. Open WhatsApp on your phone at least once every two weeks and your scheduled messages keep going out.

What happens if Chatmaid gets disconnected from my WhatsApp?

Scheduled messages cannot go out until you connect again. Reconnect with Connect with code while your phone is on, then open Completed in Message History to see which messages failed in the meantime and schedule them again.
