China Construction Bank suddenly charged a short message fee.

First of all, it won't affect your reputation. This short message service is an additional service, which only needs to be delivered to 2.5 yuan (3 yuan in some areas) every month. This function is mainly to remind your account changes in time when you withdraw cash from this card or swipe your card. If you need this service, you can pay it every month. If you don't need it, you can directly take my ID card and cancel it at the bank.
