Do Data earned through upgrades roll over?

It's only the data from your plan that rolls I'm afraid.

I applied a 100mb upgrade a couple of weeks ago, and according to my usage chart, it is still good for another 74 days.

Upgrade data lasts for 90 days with no roll over. Plan data lasts for 30 days with 60 day rollover, so 90 days as well. So essentially, upgrade data lasts as long as plan data.

Thanks for all replies. So 90 days as well . It's great.

Awesome system.

Yes, I love this idea of data rollover from Fizz. That's one of the reason I switch.

The upgrades have to be used within a couple months, but once applied they last for 2 years (apparently).

Some are confused,

Upgrade used to last 24 month once it's apply to your plan
Perk expire after 90 days you get them and once you apply them to your plan don't rolled over to the next month
