Does the bank have the right to deduct the customer's one-year SMS reminder fee privately?

Will be charged according to one year, because the SMS reminder function is prepaid, so there will be no refund. A more reasonable explanation is that you will sign a contract with the bank for one year on the premise that you open and pay for this function, so you will pay the fee for one year. During this period, no matter what reason you don't use this function, it will be regarded as an individual's early termination, which has nothing to do with the bank.
