How to treat the SMS safe deposit box service of China Mobile?

I feel that the situation of our business is not exactly the same as that of Beijing. Try to explain this business in our province. I only know what I know, for reference only. SMS safe is a very old business. At that time, it was mainly to solve the problem that the storage capacity of mobile phones was relatively limited in the early morning. In the past, mobile phones could only store dozens or hundreds of short messages, which was not so convenient to use. Therefore, Mobile provides a web page. After opening the SMS safe deposit box, the mobile phone inbox can operate like a web mailbox. I'm not a business department. I don't know if I've kept this business until now, but there are a lot of old businesses that haven't been cleaned up, and only sporadic users are using them. If you stop, you will be complained by them, that is, it is always left behind. This service can be opened through CRM, web portal and SMS (I'm not sure whether Beijing Mobile provides other ways to handle this service, such as the popular WeChat or mobile APP, but I think it's too old and unlikely). The possibility that the CRM system is broken is even more difficult than going to heaven. I don't think it's necessary to think about it. It should be that the user's service password is leaked, handled through the website, or the mobile phone virus automatically sends text messages to deal with these two situations. The opening process of this service in this province is probably as follows: with the service password or SMS random code, log in to the online business hall, that is, the website of 10086, and you can handle this service; Or send the corresponding short message from the user's mobile phone for processing. On the corresponding web page, users can enter their own SMS safe deposit box with SMS random code, and then they can see their inbox and outbox inside. Therefore, even if the other party uses the service password to handle business on the website, and all the short messages are synchronized to the safe deposit box, you still need to check the random code of the short messages when entering the safe deposit box. This should be inevitable, or the business process in Beijing may be different from mine, otherwise I haven't figured out how to get it done here yet.
