I have a used Alcatel flip phone from the US. I just got my Koodo sim card but it says ‘invalid sim’. I realized it’s locked so I entered IMEI for Koodo to unlock but it says ‘invalid IMEI’. I triple checked the IMEI and I have the right 15 digits. Why doesn’t Koodo recognize the IMEI? Is there another way to unlock it?
