To send SMS messages to the Chinese mainland, you must create an SMS signature and a message template and get both approved.
Due to policy restrictions, Go China is not available for new users. Existing users must complete identity verification for their SMS signatures. Unverified signatures may be forcibly deactivated, causing service disruptions. Verification requirements and procedures have been sent to your Alibaba Cloud Message Center and associated email.
Prerequisites
An Alibaba Cloud enterprise account that has completed verification. Register on the registration page and verify in the Account Center.
