How to send anonymous short messages by mobile phone!

At present, mobile phones do not support anonymous short messages, but calling can open the hidden business of callers.

Refers to the refusal to display the calling number on the other party's mobile phone when making a call after the fixed line or mobile phone has applied for service. Also called calling number rejection. People in the industry call this value-added service "CLIR" (whether the called party has applied for the calling number display function or not).

According to the different terminals of the called user, the information refused to be displayed is generally "-p-", "unknown", "no calling number", "confidential incoming call" and "private number". The called user can't identify the caller and can't call back, query and save.

This business is mainly used in secret organs, military and other special industries, not mainly for ordinary individuals.
