Sometimes you may have to send an urgent message on your smartphone. However, after drafting the message and tapping Send, all you get is Message Not Sent. You keep trying to resend the same message a few more times but the above message is all you see on the display. This is frustrating and undesirable. In this guide, I will tell you why this may happen and how to fix this issue. Normally, in dual SIM phones, we use one number as a primary medium for calls and messages.
However, if we have mistakenly sent the second number as sender and receiver of messages, then it won’t work unless it has a valid telecom/data plan. Normally, users have a secondary number as the WhatsApp contact number. Most people do that. So, this is where sending messages through the SIM without an active plan will lead to a Message not sent error. Apart from this, there can be many minor factors that may cause this error. I have discussed all that in detail in the guide. Check it out.

Have you Blocked the recipient?
You need to check whether you blocked the contact number, so when you send a message, it won’t deliver.
- Open the Phone app
- Tap on the upper right corner > select Settings

- in the subsequent menu select Blocking Settings
- Under that tap on Blocked Numbers to see the list of numbers that you have blocked.

- If you see the same number you were trying to message, then tap on the x to unblock the number.
