Shortcodes do not seem to work with Fizz
Canadian Tire bank sends SMS notifications in case of a suspicious transactions. I was unable to confirm the legitimate transaction because Fizz network is unable to deliver the SMS messages back to their shortcode!!!! Luckily, I was able to use another credit card. But this is a nasty surprise, something that works with any Canadian operator does not work with Fizz and can make you stranded somewhere, unable to finish your financial transaction.
Fizz, why the shortcodes do not work on your network????!
