In daily life, the endless stream of spam messages and harassing phone calls is overwhelming. In response to this question raised by netizens, Shang Yanming said that mobile companies attach great importance to the protection of customers' rights and interests and have been taking technical and management measures to crack down on all kinds of bad information, harassing phone calls and communication information fraud. In addition, for harassing calls, mobile companies have specially launched the "high-frequency harassing call interception service". Users can start this free service by sending "ktfsr" to 10086.
