Mobile phone sends text messages to hide numbers.

You can't hide the number by texting, but you can hide the number by calling. There are two ways:

First, open the call hiding:

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.

Second, the use of VoIP:

Internet phone, also known as VOIP phone, is a direct call to the other party's fixed phone and mobile phone through the Internet, including domestic and international long-distance calls.

Software phone is to download software from a computer, then buy a network phone card, and then talk to the other party (fixed line or mobile phone) through headphones; Hardware telephone is more suitable for companies, telephone bars and so on. First, you need a voice gateway. One side of the gateway is connected to the router, and the other side is connected to the ordinary telephone, and then the ordinary telephone can be freely called out directly through the network.
