I would like to transfer from a monthly plan to prepaid. I have an iPhone 4. How do I do this? I was told that I need to buy a $20 sim. Where can I buy it and what do I do next? Where can I choose what I want and how do I pay for it? I have a question regarding the base plan of $15/month so I am hoping I could go to Walmart (this is where I bought my phone from) and ask about it before I fully decide to do the transfer. If I went with the $15/month with the $25 500 minutes top-up, will it be $35 for the first month and just $15/month for the following months? Will the remaining minutes just keep on carrying on to the next months or will it eventually expire? Is there a minimum amount of minutes that you need to use per month? Will not using the minutes at all cause the account to be considered inactive or be deactivated? Could I possibly call Koodo and ask about this?
