Who I have the same questioned this topic

I have not been able to receive text messages over the past few months. This issue has only been brought to light as I have been able to successfully send them and most my contacts use calling, IM, or other means of communication to respond. However, I looked at the texting history of one my contacts and saw discrepancies dating back to months ago where they sent a response I never got. I only recently became aware when I never got SMS verification for several 2FA services. I have tried powering on and off the phone, putting in airplane mode and back, resetting network settings, clearing SMS app's cache, and no change.
