No one wants to deal with a messaging app that won't send out messages properly. Luckily, if your WhatsApp is not sending messages or the messages are not delivering we have some simple fixes that can help you with this problem.

WhatsApp messages not delivered is a common issue and there are tons of ways to get your app working right again!

Part 1: Top 13 Ways to Fix WhatsApp Message Not Delivered

1Check the Service Status

If you are trying to send your message through cellular service and it won’t send, check your service status to fix WhatsApp not sending messages.

Look at your service icon at the top of your phone screen and see if you have any cellular service. If the cellular service in your area is low, then try to move around to get a better signal. You can also wait to send your message till your service signal gets better.

2Check Your Internet Connection

A weak or unstable internet connection is one of the top reasons for your WhatsApp message not delivered. If your Wi-Fi isn't working, then WhatsApp won't work right.

Look at your Wi-Fi router and see if it's connecting to the internet. You should see an internet icon flashing green.

If your internet is not connected, reboot your router. Unplug your router and wait for thirty seconds, then turn it back on.

Let your phone reconnect to your Wi-Fi and try to send your message again.

3Check If Contact Your Messaging Has Blocked Your Number

Another reason you might not be able to send your message is if your number is being blocked or if you have accidentally blocked someone else's number.

Go to WhatsApp and go into your Settings > Account. Click Privacy.

Scroll down to Blocked Contacts. You can see all your blocked contacts.

But if you have accidentally blocked someone then click the blocked contact and press the Unblock option.

4Check Haven't Completed the Initial Verification Process

You need to completely finish the verification process to successfully send messages on WhatsApp. You can reinstall the app first and then follow these steps.

When you sign up for WhatsApp enter your real phone number. Then you will get a verification code. Check if it has been sent to your phone number via text.

It should be a 6-digit code. Look at it then go back to WhatsApp.

Enter your code into the verification box to complete the verification process.

5Check the Phone Number Format

The phone number you enter needs to be formatted correctly so your message will be sent. Especially if you are sending a message to someone in a different country.

Go to your chat and click on the phone number. Make sure that the format is correct.

If the phone number is from the same country as you just enter it normally.

If the number is international, enter a plus sign also put in the country's code. After you put in the full number.

Exit your app then open it back up and see if the message sends with the changed format.

Use the app to lock WhatsApp. Then you can safely browse and use your phone without worrying about your messages not being sent.
