Why didn't it reflect the opening of the postal green card SMS reminder service?

You have to confirm whether you have opened this business and whether you have helped you to open online banking.

If it is opened, you should take your ID card and card to the bank to check. Maybe the staff entered your number incorrectly when you opened it, or maybe your mobile phone number was changed instead of going to the bank to change it.
