7.

Since for overseas users, it will take about 3 weeks to receive this ordinary mail that contains your Debit Card PIN. Too Late.

Instead, after 2-3 working days, call Service Phone to ask the representative to send the PIN to your Secured Mailbox.

Don't worry, even without OneToken, you could still access your Secured Mailbox, by logging into OCBC app via Access Code, Access PIN and the OTP sent to your phone number.
