What does it mean to unsubscribe in the text message?

If you see the prompt "This SMS has been unsubscribed", it means that your mobile phone number has been unsubscribed from SMS subscription service. There may be many reasons for unsubscribing from SMS subscription service, such as unsubscribing yourself, or the operator blacklisted your number because of illegal behavior.

To solve this problem, you can first try to contact the operator and ask whether the unsubscribe restriction can be lifted. If the operator confirms that the restriction can be lifted, you can continue to use the SMS service. If the operator can't lift the restriction, you may need to change your mobile phone number to continue using SMS service.

If you are not sure whether you have unsubscribed from the SMS subscription service, you can also try to contact the operator and ask if there is any unsubscribe record. Operators should be able to help you find relevant information.
