After the computer sends a short message to the mobile phone, can it remotely modify the content of the sent short message?

Note: At present, the SMS platform only has the sending function, and the remote SMS cannot be modified. The sent SMS is no longer a part of the sending process, which means that the last communication has ended, so it cannot be modified.

Remarks: I suggest you read the content carefully before sending a text message, and send it to those people before sending it.
