Normally, this problem can be caused by network problems on Android or iOS phones. Knowing causes is good for us to deal with unexpected problems.

Reasons: Main Causes of Failing to Send & Receive Messages on WhatsApp

There are three major causes that might lead to the malfunction of WhatsApp. You can check out those below and see which one might possibly be the one responsible for your problem.

1.Bad network connection. If you're connected to Wi-Fi network, you should ensure that it's working well. Or, if you're using mobile internet, make sure that you stay in somewhere has a good signal.

2.Verification has not been completed. Make sure that you've completely finished verifying your phone number as to associate your contact with the account.

3.Being blocked by a certain contact. It's sad that it's of possibility that you are blocked by the one you're trying to text. You can tell whether you're being blocked by a person from these facts:

  • Fail to make any calls to a contact.

  • Cannot see updates to a contact's profile photo.

  • Cannot see a contact's status like "last seen" or "online" in the chat window.

Note that any messages sent to a contact who has blocked you will always show one check mark (message sent), and never show a second check mark (message delivered).
