Not Able To Send Message

[HowellKessler]

Hello folks. Occasionally, I encounter an error stating that 'iMessage needs to be enabled to send this message' when trying to send a message on my iPhone 13 Pro 128GB model. Can anyone help me to solve this issue? Thanks in advance.

P.S. Solved the issue with the help of this article's steps.

I know it is stating the obvious, but under Messages in settings, is it definitely on?
