You can see if there are mobile phone signal towers built by China Mobile, China Unicom, and China Telecom within three or four hundred meters of your home because mobile phones need to communicate and surf the Internet normally, and there must be signal towers around. If there is no signal tower or the distance is too far, there will definitely be situations where the mobile phone cannot be used normally. If there is a signal tower within three or four hundred meters (or closer), and the mobile phone cannot be used normally, it means that a wifi jammer is installed near you, which is a device that shields the mobile phone from receiving base station signals. The greater its power, the larger the shielding area. If this is the case, it is necessary to increase mobile phone signal towers to fight against it.
