With the continuous development of Internet technology, our lives have become more and more inseparable from the support of the network, and nowadays, in addition to smart phones, Wi-Fi is one of the important ways to obtain the network. But most people have this question, after the mobile phone is connected to Wi-Fi, should you turn off mobile data? Why does the traffic sneak away when I connect to Wi-Fi for 24 hours?
I believe everyone has this question with the author. Your mobile phone is obviously connected to Wi-Fi 24 hours a day, but the data traffic will always slip away unconsciously. Go, why on earth? In this regard, China Mobile officially explained.
First of all, we need to figure out the relationship between the two. Mobile data and WiFi are signals of different frequency bands, and the two will not conflict or interfere with each other. If mobile data and WiFi are turned on at the same time, then the phone will have priority Use WiFi network. However, it should be noted that after a successful Wi-Fi connection, mobile data traffic is not completely used. For example, in the following scenarios, even if Wi-Fi is connected, it may still run traffic!
First of all, when the Wi-Fi signal is unstable or interrupted, the mobile phone may switch back to data traffic by default. For example, when we watch a video or play a game, most of the playback is a caching mechanism. After Wi-Fi is disconnected, the mobile phone will automatically turn on mobile data for caching.
Secondly, when public Wi-Fi has a time limit, it will automatically switch back to the data network after expiration. For example, use free Wi-Fi on the subway, but after the specified time, you will use your own Data traffic; In addition, due to the problem of mobile phone settings, the Wi-Fi connection was actually unsuccessful; in the end, it may be that 手机系统 will automatically switch to the data network when the Wi-Fi connection signal is weak.
As we all know, with the advent of the 5G era, network speeds will become faster, and traffic will naturally be consumed quickly. So, what can be done to avoid traffic sneaking? The author suggests that you can set the software with high data consumption to only be used in the Wi-Fi environment, and I will tell you a small method. If it is an Android phone, you can open the phone [Settings]-[WLAN]-[Advanced Settings] -[WLAN Assistant]-Turn on [Enable Prompt], and then it will prompt when the mobile phone has a network switch; the iPhone is the opposite of Android phones, you need to turn off the WiFi Assistant, open [Settings]-[Cellular Mobile Data]-turn off [Wireless LAN Assistant].
In addition, China Mobile also gave several suggestions. First, after successfully connecting to Wi-Fi, you should immediately turn off the mobile data function to ensure that the mobile phone does not use data at will; second, set the WLAN connection, and when the Wi-Fi network is disconnected, it will prompt whether you need to use mobile Internet connection.
In general, when the Wi-Fi network is not in a "stable and unblocked" state, it will cause traffic consumption. For example, the above example is a scenario. Therefore, after successfully connecting to Wi-Fi, turning off the mobile data is the most reliable way!
