If you want to keep the content of short messages safe and confidential, does Telecom have such a service?

Short message storage service is a comprehensive service that both the calling party and the called party can subscribe to. After subscribing to this service, the short messages sent/received by users will be automatically stored in the user's short message storage box. Users can query the SMS records of the safe deposit box through the self-service website. When the safe deposit box reaches 80% of the set capacity, it will receive an automatic notice from the system. Click on "official website" Customer Service 2 17 below for more service offers.
