I often get spam the next day after I check into a hotel.

You can download some cleaning software.

The ways to stop spam are as follows:

1, the number starts with 106: this number can be recorded and blocked by 100 10 manual customer service;

2. Android mobile phone users can log in to the Android version of the mobile phone business hall client, click customer service > spam report, and enter the spam report page to report spam messages.

3, there is no number, but there is a link URL: you can turn off the service/push information through your mobile phone, so it is recommended to pay attention. If you receive a spam message or malicious phone call from a certain number, you can report it directly to the hotline 100 10 or online customer service. The reporting format is: reporting quantity+reporting content.
