WiFi is a hardware module built into the phone!! A piece of hardware for establishing a connection to the wireless internet!! It's like Bluetooth, infrared!
Their use though, is to transfer data with another Bluetooth device! WiFi is a connection to the wireless internet! It's another way to surf the Internet, if you have broadband at home, etc., install a wireless router!
You can connect with mobile wifi! The mobile phone will use your home's broadband network to access the Internet!! The speed is the same as your computer!!
There is no operator because of the limitations of national policy! Otherwise, they would have done it a long time ago!
But now McDonald's, KFC, hotels and more! All have Wi-Fi access points! Even more so at university!! Otherwise, how can someone else's book go online? The network cable is not convenient!

wifi is a wireless local area network, as long as you have its password (or he does not set a password) you can access, and broadband is the same, no charge; In addition, it's not that there are no relevant operators in China, it's because if he allows the use of this function, his GPRS can't be sold, hehe, because WiFi is not charged, so he blocked the function.

Because China wants to develop another standard on its own, it has been boycotting its operation in China.

It's free, and places like KFC have it, and they have to pay a fee to the mobile company, only the wifi module on the mobile phone can be used, and there is no need for the network signal and traffic of the mobile phone card.

At least you don't pay for your phone.

If you take out the SIM card, isn't it obvious that you don't charge for it? You should understand this explanation very well, hehe, plus everyone's explanation of wifi!

Your understanding is wrong.
The so-called wifi is wireless local area network.
For example, you have a wireless router at home. Laptops use it for wireless Internet access. Your phone can also use this wireless network to access the Internet.
And laptop Wi-Fi is a network. Therefore, the cost is also the cost of your home broadband.
