How to unblock number?

I think I might have accidentally blocked Facebook/META from sending me texts, and now I'm not receiving FB /META verification texts. How do i unblock Meta (If that is the problem)

If you blocked them from texting you you would need to open the Message app

"Google Messages" click your profile picture in the top right corner and select Spam & Block and scroll to find any from Facebook and open the messages and it should say Unblock at the top

"Samsung Messages" Open Samsung Messages and click the 3 dots in the right corner and select Settings and then scroll down to Block number and spam and select block numbers and blocked messages and scroll to find the number and unblock it

I am quite sure I never blocked (purposely or accidentally) FB/Meta. I also never receive verification texts from them, and I have never found a text from them in the spam & blocked section.  I had to switch to a different verification method. I just assumed there was something wrong on their end.

I just googled the number that theoretically FB sends verifications from and added it as a contact. (haven't tested if that works yet)
