You should be to pay at a store if you had a credit or debit card if I recall correctly.
And are you a prepaid or postpaid customer?  If you are a prepaid customer you can buy a voucher and use that to pay.

@jjjjaaaori33 No cash payment is taken at stores for security reasons. As per @Dinh above, credit card payment is ok.  If you are here for a few months, simply schedule a callback using Koodo Assist on our Help page and we can register your international credit card in no time. That way you’ll be able to use on our site as well.
