Around 2 months ago, I changed my sim card in my account and now I need to put the previous one back, but it does not work. No matter how many times i try it still says the card is not valid or already in use. How do I fix my sim card?

Unfortunately once a sim card is used, it cannot be used again.

You'll have to go to a Koodo store, or walmart, and buy a new one.

Did you login self serve and tried to update your phone?
SSelserve ;> mobile phone > swap mobile phones > new SIM card > enter the number.
If it's postpaid and less than 90 days, it should work .
