Hey there @Julielugo
Welcome to the community
Just to clarify, all Fido Pulse plans include a data bucket. On top of the available data on your plan, you also have access to Data Bytes. That being said, are you currently experiencing connection issues to your mobile data?
In regard to your plan, you won't be able to revert back to the old if it's not available anymore (expired). I would suggest that you reach out to us so we can have a closer look using one of these channels. Alternatively, we can also send you a PM here if you prefer.
Hope this helps!
