Why send text messages by express? Why did you pick them up at once? Why don't you send them?

Some express messages are sent immediately, and some are not sent because:

1. When the courier stored the parcel, the mobile phone number was entered incorrectly and he could not receive the message.

2. Now, in order to maintain the information security of users, e-commerce merchants require to use the virtual number simulated in the background to deliver goods. If the courier can't recognize the real number, he won't receive the message.
