I had a similar issue here is how to resolve it
Login to your Fizz account
Click on "my plan"
Click on "manage plan"
Click on "advanced parameters"
Click on "Fizz network parameters"
Click the button to resends the "notification"
Once you have received the text wait 5 minutes then reboot your phone

Do you have a plan with data? Is it working? Is it switched on? Data is required to send MMS (texts with pictures). Some people have had trouble with MMS if their wifi is switched on at the time, so you could also try to disable that when sending MMS.
