Can mobile customer service block harassing calls and text messages? Too many phone numbers is too much trouble.

Mobile customer service probably can't manage these, because there are too many harassing calls and text messages, many of which are sent in batches by software. Unless you know the specific information of the harasser, the customer service can only help you block the news of this person. Now many mobile phone softwares have similar softwares such as mobile phone housekeeper. After receiving a harassing call, you can directly mark this number as a harassing call, and then blacklist it in the settings, so that you won't receive any more calls from him, or set a white list of mobile phones, except the list.
