Why Some Numbers Cannot Receive SMSs?

If some numbers cannot receive SMSs, check the SMS sending status on the Message & SMS console.

• If error codes are displayed, handle the issue by referring to SMS Status Error Codes. For example, if the status code is MBBLACK, the phone number is blacklisted. The recipient may have replied for unsubscription. To make the number receive SMSs, contact Huawei Cloud customer service.
• If an SMS is sent successfully but the recipient number does not receive the SMS, check whether the recipient number is suspended due to arrears, whether the mobile phone is powered off, whether there is no signal, or whether the mobile phone blocks the SMS. If the mobile phone is normal but still cannot receive the SMS, submit a service ticket to Huawei Cloud customer service.
