I just received notifications from Customer service Derek(excellent service despite long waiting) he said this plan should effective immediately, not future dated as he was instructed not to do that on this promo?
So I am not sure about this as many ppl's billings cycles are different!
I need an official answer from fido!
it will start on your next billing cycle, for example it's showing 5 GB on mine and it resets in a couple days, the data will update to 10 GB automatically. Confirmed with FIDO this morning.
