Can you tell when you send a text message after your mobile phone number is blacked out?

If the mobile phone number is blacked out and the other party doesn't open the intercepted message actively, you can't see the content of the message. However, because blacklist interception is only an interception mechanism inside the mobile phone, the other mobile phone can still receive short messages but will not display them.

This is because the mobile phone blacklist is not intercepted on the operator's server, but the interception mechanism of the mobile phone itself, which only chooses to block the reminder after receiving the blacklisted phone number or SMS.

Generally speaking, the phone number is blacked out by the other party, and then sending a text message to the other party has two results:

First, I can't tell. The other party's mobile phone can receive the short message you sent. I can't see your message in my message list because it was intercepted.

Second, we can see that some Android phones will display interception reminders when they receive short messages with blacklisted mobile phone numbers. When receiving a short message with a hacked mobile phone number, the notification bar will show that the short message has been intercepted. At this time, click the intercepted SMS to enter the SMS application interface, and directly open the intercepted SMS to view the content.
