How to use mobile data to surf the Internet? I can send and receive text messages or surf the Internet with Wifi, but I can't surf the Internet with mobile data. What happened?

I suggest you try the method and have a look:

1 I suggest you put this mobile phone card in another mobile phone to see if you can surf the Internet.

If you can't get online, please ask the operator whether you owe money.

3 If it can be used, please put it into Xiaomi mobile phone, turn on the data flow switch, reset the default in the setting -APN, and then restart the mobile phone and try again.

If you still can't surf the Internet, I suggest you back up your data, restore and clear all the data (turn off the phone, press and hold the volume up+power on button to resume), upgrade your mobile phone to the newly developed system with a wire brush, and don't install the application that requires root permission for the time being to see if it can return to normal.

5 If you still can't get online, I suggest you go to the maintenance point for inspection: address and telephone number: /c/service/poststation/ At the same time, nine millet homes in Beijing, Shanghai, Nanjing, Wuhan, Chengdu, Hangzhou, Xi 'an, Shenzhen and Guangzhou have maintenance capabilities. The working hours of Xiaomi House are from Tuesday to Sunday, 10 am to 6 pm.
