Certain text messages/phone numbers are not coming through

Recently text messages from our bank are no longer coming through. Checked with the bank are all settings are correct. For testing switched the notification to voice call to get the bank code and that works, switching back to text and nothing comes through. I don't have any numbers blocked on my end. Bank says the issue is not on their end (which did work until recently).  I don't know what else I can check?  Any suggestions would be appreciated!
