After figuring out how to read the stupid numbers properly from my credit card, I have finally managed to use a newly purchased Koodo SIM to create a new account and start the transfer of the phone number from the previous provider. I have helped people do this in the past and do not recall any particular issues, but this time I am stuck.
After completing the registration (SIM number, contact info, old provider information, plan selection, boosters, auto-top up, credit card info) I get to the end of the process and try to log into the account. It claims the password is no good. I use the "forgot/reset password" link and it presents me with the custom security question I set up, so that gives me confidence that the proper email address is recorded by Koodo.
But I have yet to receive any email at all from Koodo (and nothing is in the spam folder). No "welcome to Koodo" message, no "confirm this email address" message, and no "reset your password" message.
