iPhone signal query method,Global trade certificate verification simple and easy to use. In the process of daily use of mobile phones, we often encounter poor signals, and on iPhone mobile phones, we can use some simple The single method to query the current signal quality is very helpful in solving some problems with bad signals.This article will introduce a variety of methods from conventional system settings to third-party software, hoping to help you solve the problem. The first method: Check the status bar. When we open the status bar of the mobile phone, we can see the signal received by the mobile phone. Through this method, we can roughly judge the current signal quality. On the iPhone, the corresponding small icon will be displayed on the status bar. Several horizontal lines in it represent the strength of the current signal. The more horizontal lines there are, the better the signal, and vice versa, the worse the signal. When words such as "no service", "searching" and so on appear on the status bar, it means that the mobile phone has no signal at present and needs to change the position or wait for a period of time. The second method: Check the setting bar. The setting bar of the iPhone also provides the function of viewing the signal, so that you can understand the signal strength currently received in more detail.The specific operation steps are as follows: 1. Turn on the "Settings" function of the mobile phone. Two. Select "Cellular Network". 3. On the "Network" page, you can see the signal strength currently received. The higher the value, the better the signal, and the lower the value, the worse the signal. It is worth noting that the signal difference of iPhone may be caused by the geographical location, different mobile phone service providers and other reasons, which may cause a certain error in the signal strength displayed. The third method: In addition to the above two methods, we can also query the current signal quality through some third-party software. These softwares can provide more detailed and intuitive information, such as whether it is connected to WiFi, the quality of the current signal, etc., and some software can also provide functions such as testing the network speed of the mobile phone.The following are some commonly used third-party software: 1. Network screenshot software can provide more detailed and intuitive information, including the status of WiFi, cellular data, VPN network, etc., and can also test the network speed. These functions can help us understand the quality of our network. Two. The mobile network killer software can automatically evaluate the speed and quality of each signal point and distinguish it by color, so that you can more intuitively understand the signal quality of the current network. 3. Speed test software can test the network speed of your current mobile phone, which helps you further understand your network quality and make corresponding adjustments. There are various ways to summarize the query signal, from the status bar, the setting bar to the third-party software, which can be used to help us understand the quality of our network.When we can't receive the signal, we can change the position or wait for a period of time and keep trying to find a better signal point. If the above methods still do not solve the problem, it is recommended that you contact your mobile phone service provider for consultation and technical support.
