Reply to the joke of td unsubscribe

It is best not to reply when the mobile phone receives the message of "reply TD unsubscribe". It's all scam messages.

Obviously, our mobile phones are not subscribed to related services, but sometimes we receive some spam from unknown sources for no reason. Many messages will eventually tell mobile users that they can cancel their subscription by replying to the letter "td" or "T". Can users really unsubscribe after replying? Is there any good way to filter these advertising messages and spam?

Many mobile phone users told reporters that they replied "td" or "T" according to the tips of these spam messages, but found that they could not unsubscribe at all. Spam with "td" is a trap. You were fooled when you answered the question. Network security experts said that the sender added an unsubscribe reminder at the end of spam messages, not to facilitate mobile phone users to unsubscribe, but to induce users to reply to text messages.

Song Yubo, an associate professor at the School of Cyberspace Security of Southeast University, said that when the other party pushed these spam messages, it was not clear whether these mobile phone numbers were real and valid, so he added "If you want to unsubscribe, please reply to TD" at the end, and many people did reply. Only after answering the phone did he know that the mobile phone number was real and valid. Professor Song said, "This means that once you return to TD, more spam will be pushed to you."

An article on the Internet claims that you can unsubscribe from these junk mails by replying to four "0s" (0000), and after replying, you will receive a prompt similar to "All mails sent by this port have been successfully intercepted". The reporter tried to answer four "0s" in this way, but did not receive any prompt information.
