The text message on the mobile phone shows "Reply to TD to unsubscribe". Why is it useless after replying?

At this stage, there is no solution to this spam message, and the root cause is still on telecom operators. If you receive spam, you may encounter the following situations:

1. After replying to "unsubscribe" or "TD" according to the SMS prompt, similar SMS really doesn't appear any more. This situation is rare. I can only say that you have a good personality and your luck is bursting.

2. After replying to "unsubscribe" or "TD" according to the SMS prompt, similar SMS messages became more and more intense. Then congratulations, you have been recognized as an active user by the sender of the advertisement short message. Because similar spam messages are sent with more numbers, the sender can't confirm whether your number is empty at first, but your reply message makes the other party confirm that this number is being used, so he pushes more spam messages to you.

3. Can I unsubscribe from SMS by replying to "0000"? There are rumors that after receiving spam messages, you can completely unsubscribe from this number by directly replying to "0000". However, neither China Mobile, China Unicom nor China Telecom have made it clear that this method is true and effective. In fact, the "0000" forced unsubscribe service refers to unsubscribe from the customized value-added services on the operator's business platform, such as purchased traffic packets and color ring tones.

Spam messages are sent by third-party channels, which are not within the scope of the operator's business platform, so replying to "0000" cannot block spam messages. In addition, some operators said that although they can help users block service-oriented short messages starting with "106", many useful short messages are also sent through "106", such as the verification code of the website and even some government information, so it will bring great inconvenience to life to easily block "106" short messages.

4. Use the mobile phone's own security software to block spam messages. Although this method is useful, it can cure the symptoms but not the root cause. Users who often receive spam messages may find that even spam messages with the same content may not send the same number. For example, the contents of the two short messages below are basically the same, but the sending numbers are completely different.

Therefore, even if a message is blocked by using mobile phone security software, the sender of spam may have changed the number the next time he pushes a message with the same content, so it is not feasible to block a single number. The best way is to block spam messages according to keywords, such as "selling houses" and "shops", add all these words to the blacklist, and automatically filter them out when they are received.

Unfortunately, most smartphones only support number blacklists. To use the keyword blacklist, you must use a third-party app, which is more complicated to use. There are not many ways for ordinary users to say goodbye to spam messages completely. Only telecom operators can control spam messages.

Unfortunately, due to various reasons, operators are not active in dealing with spam messages, and there is no unified "unsubscribe" rule. The reply to "unsubscribe" spam messages is useless and even more and more rampant.
