The mycard serial number I received isn't working. Did I use it wrong? (I'm new) Is the PIN code the password?

Don't worry, the PIN is indeed the password, usually 4 to 8 digits. Please first check if the serial number was entered correctly. If it still doesn't work, we recommend checking the tutorial at the official top-up center. If that still doesn't work, you might need to contact customer support to check the status of your serial number.
