Sometimes mobile phones send text messages without displaying the number.

First, when an email sends a free SMS, the number will be displayed in the first SMS within 24 hours. Later, when it is sent to the same person, the system will automatically identify it as an ordinary contact, and sometimes the number will not be displayed.

Secondly, the display number of Easy Letter Free SMS is a random serial number starting with 1065 or 1069 or 1 18065. But the content of the message is: from the sender of the email, email nickname+(the full name of the sender's mobile phone): Hello, ... (the content of the message)+small tail [reply to pb blocked users, please contact email customer service for complaints]
