Chinese Mainland SMS Signature

Overview

An SMS signature indicates the official sources of any SMS it is attached to. It is created based on the user identity and requires various used details to create. The signature must be approved before it can be used.

For example, in the SMS "[Huawei Cloud] Your verification code is 123456 (valid within 5 minutes). To ensure your account security, do not provide this verification code for anyone." [Huawei Cloud] is an SMS signature.

Notes

No signature can be added if your Huawei Cloud account balance is insufficient. In this case, top up your account by following instructions provided in Topping Up an Account. If you have topped up your account and the signature cannot be added, log out and log in to the system again.
Only Chinese mainland SMSs require SMS signatures. By default, a maximum of 200 signatures can be created for each application. To increase the quota, submit a service ticket or contact the account manager. For details about signature rules, see Chinese Mainland SMS Signature Rules.
Only rejected SMS signatures can be modified. You can add a signature and submit it for approval.
Signatures with the same name and type cannot be repeatedly added for the same account.
