Why does texting show my number?

This may be that the other party has opened a hidden number service. As long as you use your number to call the operator's customer service phone, you can open this service. Not only do you send text messages, but the other party can't see your number.

At present, China Unicom has launched a "shadowless SMS" service for Jiangsu users, and the number is directly added with 80. After receiving the short message, the other party will no longer see the sender's mobile phone number, but an ID number automatically generated by the system.

Mobile phone users can also use the SMS hidden number service. Dial 0 1 1230 before the mobile phone number, and the number will be automatically hidden in the sent message. The receiver only sees the virtual number, so it is impossible to know who the sender is.

Short Message Service (SMS for short) refers to the text or digital information directly sent or received by users through mobile phones or other telecommunication terminals. The number of characters that users can send and receive SMS at a time is 160 English or numeric characters or 70 Chinese characters. ?

On April 8, 2020, China Telecom, China Mobile and China Unicom jointly issued the White Paper on 5G SMS, which made the basic SMS service in China enter a comprehensive upgrade channel, and the traditional SMS will be gradually replaced by 5G SMS (RCS service).
