Spam SMS prompts to cancel subscription order.

If you see the prompt "This SMS has been unsubscribed", it means that your mobile phone number has been unsubscribed from the SMS subscription service. There may be many reasons for canceling the SMS subscription service, for example, you cancel the subscription yourself, or the operator blacklists your number because of illegal activities.

To solve this problem, first of all, you can try to contact the operator and ask if you can cancel the unsubscribe restriction. If the operator confirms that the restrictions 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. The operator should be able to help you find the relevant information.
