Since the latest update to 16.3.1 in the last week or so, I have not been able to receive any Two-factor authentication codes from various sites. I do not know if this has any bearing, but that is the only thing that has changed. Any ideas?
iPhone 14 Pro, iOS 16
Have you contact your carrier?
Check also the SMS plan.
Remove and reinsert the SIM card.
If it doesn't help visit your carrier, maybe the SIM card is damaged, ask for a replaced (new) card. Normally it is free.
Ask also to check if the SIM tray is bent, as even a tiny misalignment can cause the SIM card to not fully connect with the internal contacts in your iPhone.

Thank you for you help. The 2-factor authentication in now working. For others reading this, the best I can figure is that I updated the app from my carrier. They must have just put out an update as I am good to try to stay up on these. Having done that, all is well again.
Thank you for your prompt reply. Maybe I should have been more clear. I have been getting the 6-digit codes until about a week ago. Now all of a sudden I do not get them. Happens on various sites. I have restarted my device and it did not help. I have changed no settings other than the iOS update.
👍
Thank you for your feedback and you're welcome.
