2-factor text not being received

I am no longer getting my 2-factor texts. Nothing about my phone has changed. MY number has not changed in 5 years. I am getting texts for other companies and people. I have not messed with my phone plan I have Google fi. Ring support just ended up removing text 2-factor an went back to email. But I prefer to get text. They said I could try to add my phone number back in 72 hrs. But I might be back where I started.
