Cannot send or receive SMS/MMS on iPhone 11 or MBP (2017)

Recently I updated my iPhone 11 to 15.4.1 and it has been working fine without any hiccups. I decided last night to update my MPB to Monterey as I needed an updated OS to support Node.js, but I digress. After updating, I thought it was fine, but this morning I found out I am unable to send or receive SMS/MMS. There would be times messages will send and receive, but majority of the time it fails to send. Most of the time I get the green progress bar on the top, but to no avail.

I reset my network on my iPhone and it worked for a good 10 minutes, and then it stopped. I reset both my laptop & phone in hopes that would fix the problem, but it did not. I do not believe it is my carrier issue as I can make and receive phone calls. I have all the settings on my iPhone to forward texts over to my laptop as well so that ticks off the general troubleshooting I found from previous threads & Googling.

I am not sure how to fix this issue and I hope somebody has had this same problem & fixed it. I reached out to Apple Support and the person was not any help other than telling me "iMessage and SMS/MMS are different," yes I am well aware of that, but that does not fix my problem.

Hopefully, someone out there has an answer because I've exhausted all my options and this is very frustrating.
