Will the intercepted SMS show that it has been delivered?

Blocked messages do not show that they have been sent. When a short message is intercepted, it is usually blocked, hidden or deleted directly, so the sender cannot receive any information about whether the short message has been delivered. There are many ways to intercept short messages, such as blacklisting mobile phones and using third-party interception software. These interception measures will prevent the intercepted short messages from being displayed on the receiver's mobile phone, making it impossible for them to notice the existence of short messages.
