Just to say it here, vouchers can be bought in quite a few stores and a couple places online. Some store clerks might think of them as cell minutes. They aren't. They're a dollar value that you add to your account. You get a 12 digit code or PIN. Then you can dial 611 and enter the 12 digits in to add money to your account. If you add enough to your account that takes you over your plan cost when suspended, it will unsuspend or reactivate the current plan.
Then you can use the text option for the 2FA part of logging in to the account and change your card.
There is also a thing called real time payments that a few stores do. You give them your phone number and they add money to your account. Same result.
