How to block advertisements with universal calculator

Take Huawei mobile phone as an example:

Settings-Applications and Services-Application Management-Drop-down (Universal Calculator, or Search)-Permission: 1, Prohibited (media and files, telephone, prohibiting installation of other applications while running, background pop-up) 2. Selection: Traffic Usage-Prohibit all traffic data and WLAN. When you turn the computer back on, there will be no annoying advertisements. My own personal test is absolutely effective.

Analysis principle: advertising pop-ups need to use the network, and disabling network pop-ups will be invalid. This method can also be used to prevent software from upgrading automatically. Other similar stand-alone software can also be realized by the above method.
