The mobile phone can't receive the notification message sent by the courier.

If the courier information is not received, one possibility is that the information is intercepted as spam messages. At this time, you need to see if there is a similar interception record in your mobile guard software.

Another possibility is that the courier wrote the recipient's mobile phone number wrong!

In another case, because the network is delayed or the network is not good, you can't receive the short message. In this case, you need to go to official website, enter the waybill number or the recipient's mobile phone number (to be verified) to check the express delivery status, and then click resend SMS.
