Why is it useless to send SMS reminders when the bank card is dead?

Bank card SMS reminder is only for current accounts.

Generally, the SMS service will only remind you when the account amount changes.

Time deposit is a deposit in which the bank and the depositor agree on the term and interest rate in advance at the time of deposit, and withdraw the principal and interest after maturity. Time deposits are used to settle accounts or withdraw cash from time deposit accounts. If customers need funds temporarily, they can apply for early withdrawal or partial early withdrawal.
