Most stores don't carry $100 voucher, but you can buy 2 of $50 voucher (also not popular).
My friend, which I referred to Fido, called the customer service to activate them and to extend time to 365 days.
But, the agent charged $1 service fee and didn't give him fido reward dollars.
Hi sue 1947,
I can suggest to refill the prepaid account with a debit card or credit card on Fido.ca to avoid any fees (Log in My Account and follow the instructions in the Payment Information section). You can also make this transaction with a credit card via the IVR or directly from your phone which has no fees.
