What does it mean to notify the starting amount of 50?

For example, if you set it to 50 yuan, you will only be notified by SMS if you spend more than 50 yuan. If you are dissatisfied with 50 yuan, you won't send short messages.

Accordingly, if it is the initial notice balance, it means: I will inform you when your balance is reached.

For example, if you set it to 5000 yuan, you will be notified if the balance exceeds 5000 yuan, and you will not be notified if it is lower than 5000 yuan.
