📌 What the Clock Icon and Ticks Mean
Before changing settings, check what WhatsApp is showing next to the message.
- Clock icon: WhatsApp has not sent the message yet. This usually points to a connection, app, or device issue.
- One grey tick: The message left your phone but has not reached the recipient’s device yet.
- Two grey ticks: The message reached the recipient’s device, but it has not been read or read receipts are off.
- Two blue ticks: The message was read, if read receipts are enabled.
If messages are stuck on the clock icon, start with your internet connection and app/device checks. If messages show one tick, the problem may be on the recipient’s side, their connection, their phone, or their WhatsApp settings.
📶 1. Check Your Internet Connection
Most WhatsApp sending problems start with an unstable or weak internet connection. Even if other apps appear to work, WhatsApp may still fail if the connection drops, switches networks, or becomes too slow.
Try these steps:
- Switch from Wi-Fi to mobile data.
- Switch from mobile data to Wi-Fi.
- Turn Airplane Mode on, wait a few seconds, then turn it off.
- Restart your router if you are using Wi-Fi.
- Move closer to the router.
- Turn off VPN temporarily if WhatsApp is not connecting.
- Try opening a website in your browser to confirm the internet is working.
If WhatsApp works on Wi-Fi but not mobile data, check mobile data permissions. If it works on mobile data but not Wi-Fi, restart your router or try another network.
🔒 2. Check Mobile Data and Background Settings
If WhatsApp is not allowed to use mobile data, messages may fail when you are away from Wi-Fi. Background settings can also affect how reliably WhatsApp works when the app is not open.
Check these settings:
- iPhone mobile data: Settings → WhatsApp → Mobile Data
- iPhone background refresh: Settings → General → Background App Refresh
- Android mobile data: Settings → Apps → WhatsApp → Mobile Data & Wi-Fi
- Android battery/data restrictions: Settings → Apps → WhatsApp → Battery or Data usage
Make sure WhatsApp is allowed to use mobile data. On Android, also check that WhatsApp is not heavily restricted by battery saver or data saver settings.
If messages send on Wi-Fi but fail on mobile data, this setting is one of the first places to check.
🔄 3. Restart WhatsApp and Your Phone
If WhatsApp has a temporary connection or sync problem, restarting the app can fix it quickly.
- Close WhatsApp completely.
- Wait a few seconds.
- Open WhatsApp again.
- Try sending a short test message.
If messages are still stuck, restart your phone. A full restart can refresh the network connection, app background services, and temporary system glitches.
Before reinstalling anything, restart WhatsApp and restart your phone. It is quick and often fixes temporary sending issues.
🔐 4. Check App Lock or Privacy Locks
If WhatsApp is protected by App Lock, Face ID, fingerprint lock, or another privacy lock, make sure the app is fully unlocked before testing message sending.
App Lock does not usually break WhatsApp by itself, but it can make the app feel stuck if WhatsApp is waiting for authentication, especially after reopening the app or switching between apps.
Path: WhatsApp → Settings → Privacy → App Lock
To test, unlock WhatsApp fully, keep it open, and send a message again. If you use a third-party app locker on Android, temporarily disable it and test WhatsApp.
💾 5. Check Device Storage
If your phone is extremely low on storage, WhatsApp may struggle to send messages, download media, create backups, or process files.
Check storage here:
- iPhone: Settings → General → iPhone Storage
- Android: Settings → Storage
Try freeing space by deleting unused apps, large videos, duplicate downloads, or old files. If WhatsApp is failing only when sending photos, videos, or documents, storage is especially worth checking.
🌐 6. Check Linked Devices If the Problem Happens on WhatsApp Web or Desktop
If messages are not sending from WhatsApp Web or WhatsApp Desktop, the issue may be with the linked session rather than your phone app.
Path: WhatsApp → Settings → Linked Devices
Try this:
- Open WhatsApp on your phone.
- Go to Linked Devices.
- Log out of the computer session that is not working.
- Open WhatsApp Web or WhatsApp Desktop again.
- Link the device again.
⬆️ 7. Update or Reinstall WhatsApp
An outdated WhatsApp version can cause message sending problems, especially after phone updates or system changes.
First, update WhatsApp:
- iPhone: Open the App Store → search WhatsApp → Update
- Android: Open Google Play → search WhatsApp → Update
If updating does not help and the issue continues:
- Back up your chats first.
- Delete WhatsApp.
- Restart your phone.
- Install WhatsApp again from the App Store or Google Play.
- Restore your backup during setup if available.
Before reinstalling WhatsApp, back up your chats if you want to keep your messages. Reinstalling without a backup can lead to lost chat history.
🚫 8. Check Whether the Issue Is Only With One Contact
If WhatsApp sends messages to everyone except one person, the problem may not be your internet or app. It may be related to that contact, their phone, their connection, or your chat with them.
Check this:
- Can you send messages to other people?
- Can other people message the same contact?
- Does the message show one tick instead of a clock?
- Has the contact changed phone number?
- Is the contact’s phone offline or unavailable?
If messages are stuck on one tick for one contact only, your message may have left your phone, but it has not reached their device yet.
A clock icon usually points to a sending problem from your side. One tick usually means the message was sent from your phone but has not reached the other person’s device yet.
📌 WhatsApp Not Sending: Common Causes
| Symptom | What It Usually Means | Best First Fix |

| Clock icon | The message has not sent yet. | Check internet, restart WhatsApp, and switch networks. |
| One grey tick | The message was sent but has not reached the recipient yet. | Wait, then test whether the issue affects only one contact. |
| Media fails | Photos, videos, or files may be blocked by storage, connection, or file size. | Free storage, switch networks, or try a smaller file. |
| Web/Desktop stuck | The linked device session may be stuck or expired. | Log out of the linked device and relink it. |
