Hey there @I9Pranay
Welcome to the Community
If your plan includes unlimited calls and texts, you won't be able to track your usage as it's unlimited. You can however track any bucket of airtime or data on the Fido mobile app or directly online on your Fido.ca profile.
Are you perhaps looking to view your usage history instead? This can be found online by downloading your detailed invoice (PDF version) but only your calling history is available though.
Hope this helps.
