What Numbers Are Presented to SMS Recipients?

Numbers presented to international SMS recipients are randomly allocated by the carrier, and the senders do not see what numbers are used. The presented numbers can be huaweicloud or any digits or letters assigned by carriers, varying in different countries and regions. The value of Channel No. on the Application Management page is allocated by Huawei. The value is only used for invoking APIs.

Numbers starting with 106 are presented to recipients of Chinese Mainland SMSs. The numbers are bound to the SMS signature and are randomly allocated by the carrier. The numbers are in the "channel number+extended digits" format and cannot be set to fixed numbers. In addition, these numbers are different from Channel No. on the Signature Management page of the Message & SMS console. The value of Channel No. on the Signature Management page is allocated by Huawei. The value is used only for invoking APIs.

Note: If you use the SMS service provided by different enterprises, record numbers starting with 106 and SMS signatures and contact the customer service to check whether the SMS belongs to Huawei Cloud.
