How to unsubscribe from fraudulent SMS?

Remember not to operate indiscriminately.

Fraudulent short messages are generally sent through pseudo base stations or by borrowing SP ports of communication operators. This kind of information is generally forced to push in one direction, which means that you may receive some fraudulent short messages without special subscription, so in real life, you can hardly find a mobile phone number that has not received fraudulent short messages. (It doesn't count if it's opened)

Based on my explanation above, if your mobile phone receives fraudulent SMS, you have no way and no need to unsubscribe. Just blacken the number. Subscription and unsubscribe are aimed at subscribing to short messages for a specific SP (mostly paid), which generally do not belong to the category of fraud crimes and are regulated by the communication industry norms. However, you can ask the customer service phone number of the communication operator whether you have subscribed to SP service, and if you have subscribed, you can also suggest canceling it. Now, any SP message is not worth a penny to you.
