What does the message show when it is hacked?
Send failed, no feedback, empty number prompt.
1, the SMS service prompts "failed to send" or "undeliverable", or displays a red exclamation mark icon.
2. In some cases, the short message seems to be sent successfully, but in fact the other party did not receive it, and the mobile phone will not receive any delivery report or reading confirmation.
3. Some mobile phone systems will mistakenly equate black with an empty number, so when sending text messages, they will prompt "the other party's number is empty".
