Hi ​@Babypickles 

Just to double check, do you have a prepaid sim or a postpaid sim?

Just to confirm, which phone are you using and what message do you get when the new PIN is rejected? 

After the correct PUK is entered, the phone asks you to create a new SIM PIN and then type it again, both entries have to match exactly. If you don't need a custom PIN, I would try 1234 (the default SIM PIN) for both.

As well, be careful with the PUK itself. Entering the wrong PUK 10 times in a row makes the SIM permanently unusable and a replacement SIM would be needed. How many times have you entered it so far? More info here https://www.koodomobile.com/en/help/puk-code
