First, do you receive any incoming calls and regular SMS (P2P) from friends? If so, it is good, at least the porting was completed successfully
For 2FA text or other system generated text (A2P), it is normal for them to start coming later. Systems take longer to find out you changed provider and to route the text correctly to the new provider (Public Mobile). Also, financial institutions (banks) or government agencies (e.g, CRA) put this delay on purpose too to avoid SIM Fraud
Usually they will start coming around the 3rd day after porting but it could take as many as 7 days for all the 2FA/A2P text to come.
Also, if the one you cannot get is a foreign bank, then it is "normal". Please note that international shortcode text, like 2FA text from US banks, are not guaranteed., it is a hit or miss. Regular international text are ok but not shortcodes. It might work on some providers sometime and experience show it will broke sometime
only Canadian shortcode text found here are guaranteed

So, it is better to check with your overseas bank and see if you can receive the 2FA using other ways, such as email or authenticator app
