Can I really unsubscribe from advertising messages by replying to 0000 and TD?

Handle this case carefully.

Chen Chong, a mobile phone security expert, said that some irregular spam messages do have "data cleaning" behavior, and replying to messages is harmful. Instead of unsubscribing, it plays the role of "test number survival" that the other party hopes. However, if it is obvious that the short message is sent from a more formal commercial service number, it is generally no problem to reply and unsubscribe according to the prompt.

Consult the service operator for the unsubscribe code.

0000 such "unsubscribe codes" really exist. Indeed, some netizens verified the method of replying to "0000" and successfully unsubscribed from SMS. However, experts also said that the unsubscribe code is set by the service operator himself, and "0000" is not necessarily a unified code. For example, users who use mobile numbers can successfully unsubscribe, but for Unicom numbers, replying to 0000 is invalid.

What needs to be answered specifically needs to be determined with the service operator.

The two kinds of unsubscribe have different meanings.

Reply "TD" according to the advertisement short message prompt, and the recipient is the advertiser; The reply of the unsubscribe code is a direct reply to the service operator, which means "complete unsubscribe". Professionals remind that if you choose "unsubscribe completely", not only will you not receive the advertising message sent by this advertiser, but you will no longer receive all the message information from the service operator, that is to say, the verification messages of some applications may also be blocked together.

This factor must be taken into account when choosing, so as not to affect normal daily use.

What should I do if I encounter spam messages?

1, you can report it in time if necessary.

China mobile users: edit the short message "report number * information content" and send it to 10086999.

China Unicom users: edit the short message "LJDXB # report number # report content" and send it to 100 10.

China Telecom users: edit the short message "report number * information content" and send it to 1000999.

Unified reporting method: Go to 1232 1 website (website:/) or call 010-1.

2. If you really want to block the information of a certain number, it is recommended to download applications such as Mobile Guardian.

Small knowledge: three channels of commercial short message delivery

1. Merchants or large organizations cooperate with operators to outsource SMS services. This channel guarantees that the unsubscribe is "TD".

2. SMS sending companies help customers send all kinds of information in groups for commercial purposes. Need to be treated with caution and report it in time if necessary.

3. "pseudo base station". It is the target of the governance of relevant departments and can be intercepted by software. Beware of fraudulent information.
