SMS messages sent to phone numbers in the Chinese mainland must contain a signature, for example, Huawei Cloud. Apply for a signature in advance. The signature is reviewed based on specific rules. Once the signature is approved, you can send SMS messages with the signature.

The signature identifies the enterprise, product, or service. Submit a letter of attorney and business license before applying for a signature.

There are two types of signatures, verification code and notification signatures. You can apply for multiple signatures. For details, see Chinese Mainland SMS Signature Rules.

An SMS template contains fixed texts and may contain variables. Verification code and notification SMS templates are available for Chinese mainland SMSs. For details, see Template and Variable Specifications.
