I set up a card in China Postal Savings Bank and started online banking. I received a text message today saying that the free trial period has arrived. What do you mean?

Hello, some provinces and cities have a free trial period for SMS notification of changes in current accounts of postal savings banks; After the free trial period, SMS will be sent to the customer's mobile phone; If it is cancelled, the Postal Savings Bank will not deduct the fee; If it is not cancelled, it will be regarded as continuing to use the business; After that, the cost of SMS notification will be deducted from your account; SMS notification service for change of current account, 3 yuan/month, 30 yuan/year; Pay Notice, 1 yuan/month, 10 yuan/year; Withdrawal notice, 2 yuan/month, 20 yuan/year; Notice of account transfer, 2 yuan/month, 20 yuan/year; I hope my answer is helpful to you.
