1. is the automatic extension period of SMS reminder. Every merchant has SMS reconciliation reminder. In 2 yuan every month, automatic extension means that you set a short message reminder for a certain period of time. After the expiration, it will be automatically extended, and the cost will remain unchanged. If there is not so much money in the account, the automatic extension function will be abandoned, and the SMS reminder function will not be available in the next period.

2. The automatic renewal period of automatic rollover is to continue saving for the same period as the previous period. For example, you used to be regular for one year, and now you are still regular for one year. In case of automatic extension, you used to extend it for one year (12 months), but now you can extend it for one month, so you can deposit it in 13 months. Interest is also calculated on a one-year basis, which is more flexible.
