try to reboot your phone
Check if the operator, the name near the signal is Fizz
Did you renew your plan today?
Do you still have minutes, if you do not have the unlimited options
To contact the support you need to go to this page https://fizz.ca/en/contact-us, Fizz push you to find your solution, therefore, you need to search in the solution hub to your solution and only after 10 seconds that you are in a solution page Fizz will give you the chat bubble.
If the chat bubble does not appear, this means that the number of sessions waiting for our answers surpasses our processing capacity. If that happens, send us a private message via Facebook Messenger or Twitter.
Your can also send a message via facebook messanger https://facebook.com/fizzca and click send a message (this is a bit slower)
