What happened when the customer received a text message about the available amount of Alibaba Cloud account?

The reason why the customer received the short message about the available amount of Alibaba Cloud's account was because he registered his account on Alibaba Cloud and authenticated his real name. According to relevant public information, users who have completed real-name authentication will get a certain amount of free trial, which can be used to experience the services in Alibaba Cloud. When your free trial quota expires, you need to recharge or open the corresponding service before you can continue to use the service in Alibaba Cloud. When your free trial quota is about to expire, Alibaba Cloud will remind you by SMS or in-station letter. If you don't need to continue using Alibaba Cloud service, you can choose not to recharge or cancel the service that has been opened. If you need to continue to use Alibaba Cloud's service, you can follow the tips of short messages or letters in the station.
