Yes, you can change your PIN at any ATM supporting this function.
Wirex takes no fees for PIN change. However, please note that some ATM operators may charge a fee. Make sure you’re aware of these before changing the PIN.
Note: Please make sure to request account balance after changing the PIN.
Why? - ATM will update your PIN in the banking system, but some merchants may still use an offline card terminal. In such cases, you may need to enter the 1-st original PIN encoded into the card. To prevent this - please request an account balance at ATM to overwrite the original offline PIN.
