WhatsApp is the most popular messaging app in the world today. However, sometimes when you try to send a message on WhatsApp, only the clock icon appears or no ticks (✓) appear. There's no need to worry. In this article, we'll explore why WhatsApp isn't sending messages and how to easily fix this problem.

Main reasons to send WhatsApp messages

1. Internet connection is weak or down

A stable internet connection is required to send WhatsApp messages. If your Wi-Fi or mobile data isn't working properly, messages won't go through.

What to do?

Turn Wi-Fi or mobile data off and then back on.
Test your internet connection by opening a website or YouTube video.
If the network is weak, move to a location with better connectivity.

2. WhatsApp server down

Sometimes the problem isn't with your phone, but with WhatsApp's servers. When the servers are down, users around the world may experience trouble sending and receiving messages.

What to do ?

Wait a while.
Ask friends if they're experiencing the same problem with WhatsApp.

3. Older version of WhatsApp

If you haven't updated WhatsApp for a long time, the older version may cause technical issues.

Solution

Open the Google Play Store or Apple App Store.
Update WhatsApp to the latest version.
Reopen the app after updating.

4. Wrong phone date and time

If your phone's date and time settings are incorrect, WhatsApp may not be able to connect to the server properly.

How to fix?

Go to Settings.
Open Date & Time.
Turn on the Automatic Date & Time option.

5. Data Saver or Background Restriction

Some phones prevent WhatsApp from using the internet in the background to save battery.

Solution

Go to Settings > Apps > WhatsApp > Battery.
Allow Background Activity.
Allow WhatsApp in Data Saver.

6. Low storage on the phone

If your phone's storage is almost full, WhatsApp may not work properly.

What to do?

Delete unnecessary photos, videos, and apps.
Try to keep at least 1–2 GB of free storage.

7. You've been blocked

If you only see one tick (✓) on a message sent to one person and no other tick appears for a long time, it's likely that the person has blocked you. However, it could also be because the other person's phone is off or their internet connection is down.

If WhatsApp is not sending messages, follow these steps.

Restart your phone.
Turn Airplane Mode on for 20–30 seconds and then turn it off.
Clear WhatsApp's cache (on Android).
Update WhatsApp.
Try changing your internet connection.
If necessary, back up WhatsApp and reinstall the app.
How to avoid this problem in the future?
Always keep WhatsApp updated.
Use a strong internet connection.
Keep your phone's storage free.
Keep checking your Battery Saver and Data Saver settings.
Always set your phone's date and time to automatic
