Which one is used when wifi and data are turned on at the same time?

Nowadays, most people use mobile phones to connect to wireless networks, that is, WiFi. But there is no WiFi in some places, so you have to turn on your own traffic. When you turn on WiFi again, you sometimes forget to turn off your own traffic, leaving both on at the same time, and you have just watched a TV series or movie. Some people will break out in a cold sweat. How much traffic will this cost? So will this situation consume my own traffic? Will it affect the network speed?

In fact, if both are turned on at the same time, there is basically no impact. First of all, WiFi and mobile data are two different signal bands, and there will be no conflict, so even if they are turned on at the same time, It will not have any impact on network speed. Secondly, smartphones will have a precise algorithm in the background. When connected to WiFi, the phone will automatically prioritize using WiFi networks, so there is no need to worry.

But it is best to turn off the data traffic when using WiFi. This is because if the WiFi suddenly disconnects while watching a video and your data is on, it will automatically switch to your own traffic. It's okay if the reminder is set for some, then the system will prompt that data traffic will be used, but if some are not set properly, it is very likely that the data traffic will be used directly. If you are watching TV and don't know that the wireless network is disconnected, Isn’t it sad that you can still watch it with gusto!

There used to be a joke on the Internet, because the current 4G network speed is too fast. If you fall asleep watching a video at night, the WIFI is disconnected and the traffic data is connected. When you wake up the next day, the house already belongs to the operator. Although this is a joke, it is enough to show the anxiety of modern people.

In fact, many regular apps now prompt whether to switch to traffic data, so everyone should pay attention when switching between traffic and WiFi.
