I was using Koodo prepaid sim card in Vancouver and returned to Korea last year. And from this weekent to August 21, I will be staying in Toronto. I want to use the sim card I used last year. Can I use it again? I want to check it with my account, but I think my account is not working anymore. I can't log-in. I tried 'forget password?' and changed my password, but still I can't log-in.
