Dear officers, I have a question. Suppose I make a mobile plan with 40G in Quebec, and 10G left for this month.
Next month I change the plan to Canada with 20G. Will these 10G in this month be added then I can use 30G for the next month?
Correct, your data is valid for 90 days (30 days of the current billing cycle + 60 days for rollover data).
During a payment cycle, the unused data from your mobile plan can be used within the two months following the end of that cycle.
