Account freeze rules
Alibaba Cloud Short Message Service reviews the qualifications, signatures, and templates that you submit. The service also uses system monitoring to prevent content that violates national laws and regulations from being sent in text messages.
If non-compliant message content is found, the user's account will be frozen. A security deposit may be deducted, or the user may be held liable, depending on the situation. After an account is frozen, you can no longer use Short Message Service and cannot reapply to activate it. Any unused service resource packages, coupons, or other resources in the account also become unavailable.
