Send messages

Send batch messages to the Chinese mainland using the Broadcast feature in the SMS console.

Important

Due to policy restrictions, Go China is not available for new users. For accounts that already have this feature enabled, your SMS signatures must undergo identity verification. Unverified signatures may be forcibly deactivated, causing service disruptions. The requirements and procedures for identity verification have been sent to your Alibaba Cloud Message Center and associated email address.

Before you begin

Complete the following before sending messages:

Create an account and complete enterprise identity verification: SMS is available only to enterprise accounts. Complete enterprise identity verification.
Activate SMS: Log on to the SMS console and activate the service.
Purchase a resource package: SMS uses prepaid resource packages by default. Purchase a resource package before sending messages.
- Add a credit card or PayPal account to your Alibaba Cloud account.
- Purchase a suitable package based on the destinations and package specifications. If you prefer the pay-as-you-go model, contact sales to enable it.
Carrier compliance requirements vary by country and region. Create an SMS signature and message template. Both must be approved before use.
