What does a trumpet do?

Wo trumpet was announced by China Unicom to launch the Privacy Protection Artifact APP this year. With this software, users can use a new number on the same mobile phone without a new SIM card.

This number can not only answer calls and send and receive short messages normally, but also set the use time, on-off state, undisturbed time and so on independently. In addition, it is cheaper for users to hold multiple mobile phone numbers, and there is no need to buy mobile phones or replace dual-card dual-standby mobile phones.

Under normal circumstances, the "secondary number" of Unicom's small products cannot be used alone, and it supports domestic voice and point-to-point SMS functions. Sending short messages to the platform number is not supported, and only short messages starting with "106" can be received. The secondary number cannot enable data function and does not support value-added services.

? Wo trumpet background:

According to the statistics of harassing calls received by 1232 1 center for reporting bad network and spam, from 20 14 to 20 19, harassing calls are still increasing year by year.

China Unicom's "Wotrumpet" can hide the real number and generate a new number that can be used at its own time. This will not affect normal communication, but also avoid being harassed for no reason in the future.
