There are harassing calls in Zhejiang Hotel at night.

This may be because the hotel resells personal information or someone in the hotel uses a device similar to a pseudo base station to automatically send signals for fraud. In this case, you can directly install a security software in your mobile phone to intercept harassing calls.

I suggest you download Tencent Mobile Manager in official website.

Use Tencent Mobile Manager-Security Protection-Harassment Interception-Turn on Intelligent Protection.

In this way, once the garbage tries to enter your mobile phone, Tencent mobile phone housekeeper will immediately start interception, and then prompt you, and can also intelligently identify fraudulent text messages and harassing calls.
