Is there a charge for unsubscribing from SMS?

No need. Hangzhou Internet Court made a judgment on the SMS case, and found that the fees incurred by users in unsubscribing from SMS should be borne by the platform, so there is no charge for unsubscribing from SMS. Unsubscribe SMS is to register with your own mobile phone number and collect the mobile phone numbers of some e-commerce platforms and social platforms, so that the third party can send these unsubscribed SMS messages to the corresponding users.
