I assume you're asking "what happens if I cancel the data early?"
The answer is yes, there will still be a Voice Credit (known as the Device Credit or SAPA) and a Data Credit (known as the DSAPA)
This is unchanged from before. Cancelling your data would result in a pro-rated chargeback of the DSAPA (just as before). The only difference is the DSAPA will no longer be capped at $200.
In the Past, SAPA was capped at $400, and DSAPA at $200 (outside Quebec). However, the data credit was always the larger credit (e.g., $445 on iPhone 5). In the new policy, if you cancel your iPhone data plan, you would be paying back $445 / 36 x remanining months. Before, you would pay $445 / 36 x remaining months, max $200. This "max" is now the total data credit value.
