Should I turn off data traffic after connecting my phone to Wi-Fi? The answer has been confirmed

WiFi is a product of the 4G era and has a history of seven or eight years. Like air conditioning, it has become standard in all walks of life. WiFi is also an indispensable connection medium for modern smart homes.

For urban residents who are a bit more frugal, they don’t even spend 1kb of data when surfing the Internet. They just need to connect to all the WiFi on the street. Do they still need to worry about Internet access?

Whether to turn off mobile data when connecting to WiFi: Two examples

For the general public, there is always such a doubt: after the mobile phone is connected to WiFi, do you need to turn on the mobile data as well? To be honest, this is actually a simple question. Let me give you two examples.

• The first is that when the mobile phone is connected to WIFI and makes a call, the phone will not be disconnected from the network (not an Internet call, but a mobile phone number). This shows that the normal communication path between WiFi and the mobile phone is different.
• The second is to turn on WiFi1 and data at the same time, and then unplug the router cable. You will find that the mobile phone really cannot access the Internet, even if the mobile phone data is turned on. This shows that the mobile phone’s network path is not the same as the WiFi path.

In fact, China Mobile has also made a similar explanation on this point, stating that WiFi and mobile data networks are in two network transmission paths with different frequencies, so mobile data can still be turned on when connected to WiFi.

Choice of WiFi, mobile phone, and network cable: WiFi is the most common, and network cable is the most stable

Currently, the three main ways to access the Internet are WiFi, mobile data, and network cables. Some people are still confused about the choice among these three. So how do the three perform? Let me give you a simple scientific explanation.

Mobile data: convenient and fast, but the package fee is too expensive

Mobile data is the most convenient but least cost-effective option. Although it can help mobile phone users access the Internet anytime and anywhere, the data fee is something that must be considered, especially for friends whose data packages are not enough.

In addition to the high cost of Data Package 1, there is another problem that the mobile network is limited by the strength of the local signal, so when going to mountainous areas, some people will bring a mobile phone for the elderly.

WiFi: cost-effective, network speed is affected by walls

WiFi is the most cost-effective of the three. Not only is it cheap, but it can also connect multiple devices. Most families have it. If there are more than three people surfing the Internet at home, it is completely necessary to install broadband.

Its only drawback is that the signal is restricted by the walls and cannot be fully utilized. Sometimes it even has a mixed signal. In terms of portability, businesses have long launched portable WiFi, so there is no need to worry too much.

Network cable: One cable can only be used by one device

The use of network cables is very rare. For those who have great demands on the Internet, equipping them with network cables is a necessary measure. It can ensure the continuous stability of the network and ensure the normal network output rhythm.

For example, customers who are keen on computer games need to purchase their own package and equip it with an Internet cable so that they can better cope with games that require high Internet speeds, such as "Overwatch", "Warframe", and "Blade & Soul".

A product of the same era as WiFi: HD voice call service

Another service that is closely related to WiFi is the HD high-definition voice call service launched by China Mobile. It is very interesting. They are products of the same era, but the popularity of HD is much faster than WiFi.

The so-called HD is the HD style that appears on the signal bar of everyone’s mobile phone. Its existence can greatly improve the connection speed, call quality, and video fluency of the mobile phone. It is one of the best free services launched by the three major operators.

The biggest feature of this service is that it is free, but there is a prerequisite for it to be free, which is that it will consume data. It is common sense that making phone calls will use data, regardless of whether you have turned off this function or not.

However, it is still not recommended that you turn it off, otherwise the call and video experience will basically regress to the level of 10 years ago, which would be very uncomfortable.
