I am a new Koodo prepaid customer, using an iPhone 4. I have been trying to set up two-factor authentication on several websites but I am not receiving any of the SMS confirmation codes they send. These are major websites and they all say they support SMS to Canadian carriers. I have waited more than an hour and have not received a single SMS from these websites. Is this a known issue with Koodo or am I doing something wrong? I am able to send and receive regular SMS messages to my friends/family, just not receive the confirmation SMS codes.
