Why is the 4G traffic still sneaking away when there is WIFI

Generally speaking, mobile phones will use WiFi for data transmission by default, but when the WiFi signal quality is not good, or when it is interrupted, some apps will use automatic switching to the mobile network.

Now 4G internet speed.

It's loaded, and these calculations are not small amounts.

At the same time, China Mobile's official also gave a solution, which we roughly summarized:

1. Turn off the mobile data function of the mobile phone while connecting to Wi-Fi 2. When the Wi-Fi connection is disconnected, it prompts to use the mobile data connection <>

In fact, most common apps will do a good job of protecting the user's traffic, for example, many **platforms will automatically stop **loading and** when the wifi signal is interrupted, and remind the user that the wifi has been interrupted, and if you continue**, it will consume mobile traffic. However, there are also some rogue apps that not only do not prompt, but also steal data in the background and upload a large number of users' privacy, which is the key to the problem. And for this situation, it is really difficult to prevent.

After the phone is rooted, the software can obtain the highest permission, and there may be a situation where the software with high permissions uses the traffic on its own. If you find that your phone consumes abnormal data after rooting, you can go directly to the OPPO service center to deal with it. If your phone is not rooted, you can contact your carrier to check the data usage details.

1. Since WiFi is a wireless LAN, the signal penetration ability is weak, and continuous coverage cannot be achieved, and the mobile phone may automatically switch to 2G or 3G network to access the Internet without your knowledge, such as unstable or signal interruption of the WiFi signal, resulting in Internet traffic fees.

2. Therefore, it is recommended that when you turn on wifi Internet access, turn off the mobile phone data function first, and check whether the mobile phone screen has a wifi network access logo to avoid traffic for no reason.

Summary. Workaround:

1. When connecting to the wifi network, turn off the mobile data by the way.

2. Many smartphones will automatically turn on the data network when the wifi signal is weak by default, so we'd better turn off this feature.

Android (take Huawei phones as an example): Go to Settings > WLAN > WLAN+.

iOS system (iOS 9 and above as an example): Click "Settings - Cellular Network - Wi-Fi Assistant" to turn it off; 3. When the Wi-Fi connection is disconnected, the mobile data connection will be prompted, such as Android (take Huawei phone as an example), and click "Settings - Mobile Network - Mobile Data - Advanced - Wi-Fi Mobile Data Connection Switching Prompt - Prompt to Use Mobile Data Connection".

When connected to wifi, why does mobile data still run traffic?

1. When the WiFi is unstable or disconnected, the phone may switch back to the 2G 3G 4G 5G network by default; 2. Some public wifi has a time limit, and it will automatically switch back to the data network after the use time is over; 3. Failed to connect to wifi due to mobile phone settings; 4. Some mobile phone systems will automatically switch to the data network when the wifi connection signal is weak.

Solution: 1. When connecting to the wifi network, turn off the mobile data by the way. 2. Many smartphones will automatically turn on the data network when the wifi signal is weak by default, so we'd better turn off this feature.

Android (take Huawei phones as an example): Go to Settings > WLAN > WLAN+. iOS (iOS 9 or later):

Click "Settings - Cellular Network - Wi-Fi Assistant" to turn it off; 3. When the Wi-Fi connection is disconnected, the mobile data connection will be prompted, such as Android (take Huawei phone as an example), and click "Settings - Mobile Network - Mobile Data - Advanced - Wi-Fi Mobile Data Connection Switching Prompt - Prompt to Use Mobile Data Connection".

In the era of "human beings can't do without mobile phones, and mobile phones can't do without the Internet", how do you use mobile phones to surf the Internet?

So, here's the problem:

Do I need to turn off the mobile network after my phone is connected to WiFi?

Do you need it? Don't need it? ......

If you don't turn off the mobile network when you have wifi, will you secretly run the data?

It's an embarrassing and easily overlooked question!

Here's a look: First of all, wifi and mobile data are two different frequency bands and don't conflict with each other, so even if they are turned on at the same time, it won't have any effect on the speed of the Internet.

In addition, when connected to WiFi, even if mobile data is turned on, the smartphone will give priority to using the WiFi network, so there is no need to worry about the mobile phone still using mobile data when WiFi is available.

Therefore, under normal circumstances, when the mobile phone is connected to wifi, it can't actually turn on the mobile network, and it has no impact on the consumption of traffic. Whether you open it or not depends on your personal mood

Of course, there are also unusual situations:

Sometimes, after the WiFi network is unstable or disconnected, if the mobile network is turned on before, the mobile phone will switch to the mobile network by default. Therefore, in order to prevent this kind of "stealing traffic", some functions of the mobile phone must be set in advance

Go to your phone's [Settings] - find [Mobile Network] - [Wi-Fi Mobile Data Connection Switching Prompt] - select [Prompt to use mobile data connection].

In this way, even if the wifi network is interrupted, the mobile phone will prompt you whether to switch to mobile data, and will not automatically connect, so as to avoid the traffic running away innocently!

Summary. To be on the safe side, turn off your mobile data when connecting to wifi:

There have been cases where the mobile data was not turned off after connecting to wifi, and then the phone was in arrears after the night passed. The reason is that after the wifi is disconnected, the mobile phone starts to use mobile traffic but does not remind it, and the traffic is overused unconsciously, resulting in arrears on the mobile phone. (The highest one, the monthly traffic fee cost 500 yuan, distressing!)

Therefore, in the case of unstable wifi or weak reception signal, it is best to turn off the mobile data while connecting to the wifi, or simply not connect to the wifi and use the mobile data directly! After all, not all wifi networks are safe, and wifi in public places is not safe in fact, so it is recommended not to connect!

Finally, in the Android app market, some software apps may have hidden risks. If you keep your data on when not in use, these malicious apps are likely to steal your traffic.

Therefore, you should still be cautious when using wifi in public places!

After the Wi-Fi connection, if you can surf the Internet normally, you will not use mobile data.

WiFi and mobile data are two different signal frequency bands, and there will be no conflict, so even if they are turned on at the same time, it will not affect the network speed.

What are the implications. Secondly, there will be an accurate algorithm in the background of Zhibu Qingshenneng mobile phone, and in the case of connecting to wifi, the mobile phone will automatically give priority to the use of wifi network, so there is no need to worry.

Extended Materials. To be on the safe side, turn off your mobile data when connecting to wifi:

Sometimes, the wifi network is unstable or disconnected, if the mobile network is turned on before.

Then the phone will switch to the mobile network by default. Therefore, in order to prevent this kind of "stealing traffic", some functions of the mobile phone must be set in advance

In this way, even if the wifi network is interrupted, the mobile phone will prompt whether to switch to mobile data instead of automatically connecting, so as to avoid the traffic running away innocently! Therefore, in the case of unstable Wi-Fi or weak reception signal, it is best to turn off mobile data while connecting to Wi-Fi.

Generally speaking, mobile phones will give priority to using WiFi for data transmission by default, but when the WiFi signal quality is not good, or when the internal disconnection, some applications will use automatic switching to the mobile network.

At the same time, China Mobile's official also gave a solution, which we roughly summarized:

1. Turn off the mobile data function of the mobile phone while connecting to Wi-Fi 2. When the Wi-Fi connection is disconnected, it prompts to use the mobile data connection <>

It may be because the wifi signal you are connected to is not good, so he is using the data.

Turn off the 4G traffic before connecting to the wifi, so that the 4G traffic will not be stolen, but the two do not affect.

Sometimes the wireless signal is not good, and some data will be used.

Sneaking 4G traffic, that's because its signal is not good, so it will automatically switch to 4G traffic.

It is recommended to turn off the 4G data when connected to WiFi, so that the data will not run.

Sometimes, the wireless signal is unstable, and the data traffic will be automatically turned on.

Because although it is connected to wifi, sometimes the wifi signal is not good, and the traffic will be used.

This may be due to poor WiFi signal or sudden interruption, at which point the 4G will be connected.

Because when the wifi signal is not good, some mobile phones will secretly turn on the traffic.

When it comes to the invention of wifi, perhaps many people know Heidi Lamar, who is known as the mother of wifi. Heidi Lamar is a very famous actress. Because of her first husband, she started learning wifi.

His first husband, a Jew, studied wireless communications jamming torpedoes. Due to the influence of her first husband, Heidi Lamar also began to work on wireless communication, which was the earliest prototype of WiFi. In the 90s, a research team at the University of Sydney obtained a patent for WiFi.

With the rapid development of the Internet, WiFi has entered our lives. But the advent of wifi has not completely replaced traffic, because wifi has signal limitations. Sometimes you need data to go out, so for the convenience of most people, they will turn on the data even if they use wifi.

So many people will question if they are stealing when they use wifi and turn on the data stream? Listen to what the operator has to say.

Officials say they don't "steal" data while using wifi. If wifi is available, wifi is preferred, and some software will be automatically updated under wifi. But when the wifi signal is not good, the system will automatically disconnect the wifi usage data.

For example, when you leave a wifi message or only one signal, you will automatically use the traffic. Of course, you can also turn off the traffic when using WiFi, which is a comfort to yourself and can avoid the loss of traffic outside of the WiFi signal.

No, unless the wifi is disconnected in the middle.

If your phone has cellular data turned off.

If you use wifi to access the Internet and still generate traffic, filial piety does not rule out that your mobile phone has not turned off the cellular data that has been connected to the wifi Internet, and there are also the following situations:

1. When the wifi is unstable, the phone will automatically switch back to the 2G 3G 4G network.

2. There is a time limit for public WiFi, and it will automatically switch back to the mobile network after it ends;

3. Due to the setting of the mobile phone, the wifi is not successfully connected;

4. The iOS9 system will turn on the "Wi-Fi Assistant" function by default, that is, it will automatically switch to the mobile cellular network when the WiFi connection signal is weak.

Use your phone's own mobile data. It is recommended that you go to the settings of the iOS 9 system and turn off the "Wi-Fi Assistant" function at the bottom of the cellular network settings.

If this is not the case, it is recommended that you contact the local Unicom customer service for verification and processing, and the actual situation shall be subject to the local policy.

The mobile phone is connected to wifi 24 hours a day, why do you secretly run the traffic? The sooner you know, the better.

That may be because the mobile phone has strong traffic but the wireless is not good, so the data is used first.

Because when the wifi signal is not good, 4G traffic will be used, so it will be consumed.

Because WiFi is not always stable, sometimes it will be fast and slow and accompanied by unstable network, at this time your phone will switch to data traffic, but this process is generally very short, you will not notice it at all.

It is because the wifi signal is unstable and there is no traffic transmission, so the 4G network is used.
