What does it mean to request T- unsubscribe by SMS?

T means that you don't want to receive this kind of information, and T is the pinyin initials of tui and ding.

The previous push SMS was unsubscribed without TD. It should be that the relevant state departments require that SMS advertising push must provide users with unsubscribe function, and unsubscribe is a shielding word in SMS, so it is not a reply to unsubscribe, but TD.

If you really reply to TD or anything unusual, you should be vigilant and don't come again. Because it may also be a fraud. After replying to "Cancel+Verification Code" as prompted, the funds on Alipay and bank cards will be swept away within half a day.

Extended data:

When the user replies to the letter to unsubscribe, the customer calls to confirm that it can indeed unsubscribe. However, if the user unsubscribes for many times, his SMS function will be affected, and finally he may never receive the push again.

For some unscrupulous merchants, if users reply to SMS to unsubscribe, they will be considered as active users by the system, and then push them more frequently. Even some lawless elements will set parameters in the background, and after replying to keywords to unsubscribe, it is very likely that operations such as "registration" and "consent" are being carried out in the background. Network security experts suggest that for security reasons, users are advised not to reply or blacklist until the relevant SMS system is more perfect.
