What does it mean to exceed the daily cumulative limit of encrypted SMS?

Cumulative limit of online payment on the same day using mobile phone dynamic verification code. Support can only be made within the daily cumulative limit, and payment cannot be made beyond the daily cumulative limit. You need to pay the next day or replace the U shield for payment.

For example, the daily cumulative limit of mobile phone dynamic verification code paid online is 1000 yuan, and 9650 yuan has been paid that day, so I want to buy goods from online 800 yuan again. The last 800 yuan can't afford this sum, so you can only pay with U shield, or wait until the next day to buy it.
